Why do you need a surge protector?

First, let's look at how much current the user receives at the outlet from the power plant.
Generators create a current with an EMF in the form of a sine wave. While the current flows to the end consumer, an almost ideal sinusoid becomes overgrown with interference, which is subsequently expressed in the form of noise. Harmonics are added to the voltage waveform, which will cause interference in the operation of devices connected to the network. Additionally, voltage drops and surges may occur due to increased load on the network, power outages and other unpredictable factors. A surge protector is needed to filter out network interference so that devices connected to it receive clean power, and to reduce noise coming from power supply devices. This task is accomplished by an electrical circuit, thanks to which changes in frequency and small voltage surges are simply absorbed. In the event that network problems exceed the limits set by the manufacturer, the supply of electricity through the surge protector is stopped because the fuse is tripped.

In stores you can find surge protectors with different numbers of outlets. Thanks to this, several pieces of equipment that need protection from voltage surges and other interference can be connected to one device at once. However, such filters have a maximum permissible load. For example, you cannot connect several high-power devices to them at once. It is not recommended to neglect this indicator, since otherwise the manufacturer cannot guarantee the high-quality operation of the product.

Model range of Pilot network filters

The product range of the domestic company ZIS is represented by several series. They have different levels of protection and a range of functions. Pilot surge protectors are designed for consumers with varying purchasing power and meet any voltage stabilization requirements. The equipment range is represented by the following lines:

S series;
L series;
GL series;
Pro series;
Bit series;
T series;
Single series.

Each line has a certain functionality and degree of protection.

Housing made of impact-resistant, flame-retardant plastic

Series S

Devices of this modification belong to the budget class and have a basic set of filtration tools. The design of this model provides the following means:

Varistor. Designed to smooth out impulse noise. They arise when using tools and equipment whose operation is associated with the formation of a spark: drill, hammer drill, etc.
Thermal fuse. Protects the device from overheating when the permissible power is exceeded.
Fusible and thermal bimetallic fuses prevent short circuits from overload.

The surge protector has five Euro-type sockets with grounding contacts and one for connecting old-style plugs. Models with the designation Max differ from the basic modification by increased power up to 3.5 kW and a current of 15 A.

Advice. All ZIS products are developed taking into account all the shortcomings and parameters of domestic electrical networks. Accordingly, it is fully adapted to work in such conditions.

Series L

Has all the basic means of protection. The difference is the installation of three varistors, a filter to eliminate high-frequency capacitive-type interference. The light indication indicates the current state of the device. The body is made of high-strength and refractory plastic. The rosette group is located in one row.

GL Series

It has the same protections as the S and L series models. An inductive-capacitive filter is used to stabilize high-frequency interference. The gas discharge limiter provides protection against surges during lightning discharges. The sockets are covered with special covers to prevent electric shock to the child.

Pilot surge protector – protection at a reasonable price

Pro Series

The surge protectors in this series are premium class and have advanced protection features. Network diagnostic tools automatically determine the presence and absence of a ground loop. Diagnostics is intended for installation and subsequent stabilization of the phasing of the connected plug. The contact group is made of high-strength steel, which ensures reliable contact of contacting parts. One of the sockets is made of the Gadget Parking type, which allows you to connect one plug with round contacts or two with flat contacts at the same time. Excess cords to be connected are placed in a special holder.

Bit Series

Bit line devices have only one socket with grounding contacts, do not have an extension cord and are installed directly into the socket. This modification has all the anti-interference features of the L series models.

Series T

The design and degree of protection are similar to the Bit series. The difference lies in the number of sockets, there are 4 of them in this line, and two USB ports for charging mobile phones, smartphones, and MP3 players. The device is designed for a total connected power of 3.3 kW.

Single Series

This model is equipped with one socket with grounding contacts. The configuration and design are similar to the Bit series. The device is equipped with means of protection against the appearance of 380 V in the network. When the voltage exceeds peak limits (increase or decrease), the supply of electricity is automatically stopped and resumed when the parameter stabilizes.

ZIS products meet all GOST requirements. Each series has an optimal price/quality ratio. Due to this, Pilot surge protectors are in high demand and popularity among consumers.

ZIS Pilot-PRO NEW 6 sockets

Like all surge protectors, Pilot-PRO is equipped with a high degree of protection against lightning discharge and impulse noise, and the device also has protection against short circuit and current overload. This model is equipped with a special diagnostic circuit that allows you to determine the presence of grounding on the contacts of the sockets. The body is made of impact-resistant plastic, the contact bars are made of high-quality metal, it allows you to achieve a tight grip between the plug and the socket.

I have gone through a large number of surge protectors: switch buttons on bridges burn out, but they are repairable and durable, buttons on Svens burn out, but they are made of cheap and low-quality plastic, and their buttons cannot be repaired. The pilots serve very well - at my work I even have simpler models that have been working around the clock for 5 or 7 years! After all, if you need a good surge protector and don’t mind spending your money on it. Take it.

What does the price depend on?

For a filter device that protects your computer from crashes and reboots, and information from loss, the price depends on many factors.

After reading the article, everyone can decide for themselves whether they need a filter. It should be taken into account that by saving a little and buying a regular extension cord instead, you can lose more expensive equipment.

It is impossible to imagine stable operation of a computer without a surge protector. It can protect your home hardware and appliances and also save you from data loss.

Sven network filters

The Finnish surge protector Sven appeared on the Russian market relatively recently. The bright representative of this brand, the SVEN Fort device, has a well-thought-out design. The bright design of the body, uncharacteristic of most filters, makes it stand out from the crowd of similar devices.

Unlike many of its brothers, it is not designed to lie on the floor. There are 2 holes on the back cover of the case that can hold the extension cord on the wall in a longitudinal or transverse position. There are 5 sockets on the front panel, and opposite each of them there is a red button responsible for the operation of a specific connector. There is also a button that turns off the entire device.

Two indicators on the housing indicate grounding and the operating status of the protection. The backlight color is different. According to customer reviews, the diagonal arrangement of the holes is not very convenient. When connecting some devices with elongated plugs, it is not possible to use the adjacent connector.

Inside the case:

pay;
3 varistors;
fuse 10 A.;
thermal fuse.

There is also a SVEN Fort Pro model. According to experts, this device differs from the previous one in the presence of a voltage scale, which is slightly inaccurate. Its internal structure is identical to Fort. In both devices, solder sagging is observed.

What is a surge protector

I think many (and I once) thought or think that a surge protector is an extension cord with a switch. Like this, for example, in the picture:

If you think so, then it’s time to dispel your misconceptions. If not, honor and praise to you!

A surge protector is a device that protects your electrical appliances from power surges and interference. A regular extension cord with a switch will not extend the life of your electrical appliances. A regular surge protector is very similar to an extension cord, but it has protection against the misfortunes described above.

Let's take a closer look at how it protects electrical appliances:

voltage pulses - to protect against them, the network filter must have such a thing as a varistor. A varistor dissipates excess energy, converting it into heat. If he cannot stand it, he burns out, dying the death of the brave, but the equipment remains intact. When choosing, look at the “Energy Absorption Level”, or “Total Dissipated Energy”, or “Maximum Input Pulse Energy”, or “Surge Energy” parameter, which will be in Joules (J). The larger this parameter, the better. Many devices also have such a thing as a thermal switch, which is triggered when the maximum voltage value is exceeded and cuts it off, preventing the varistor from burning out. The presence of a thermal breaker is precisely desirable so that the filter does not burn out at the first power surge and serves for a long time.
high-frequency power grid interference. An anti-interference filter (LC filter), which consists of an inductor and a capacitor, is responsible for combating them. Look at the parameter “Degree of suppression of high-frequency interference” or “Degree of suppression of high-frequency interference”, measured in decibels (dB), respectively, the more, the better.

Voltage drops

— this protection system actually complements the network filter with the function of a voltage stabilizer: the automation smoothes out critical drops and increases in voltage in the network so that the power parameters supplied to the load do not go beyond acceptable limits. Models with this function are recommended for power networks with unstable voltage (although for strong fluctuations it is still better to use an external stabilizer).

The best network filters without additional features

DAESUNG MC2343

A comfortable, energy-efficient device with electrical outlet switches. Guarantees protection against sudden voltage surges. The device from a developer from South Korea has another advantage over its analogues: the contact holes of each socket on the device are arranged in one line, which is useful if there are large external power supplies or chargers. Each switch is opened by 2 power wires, and a child safety system is provided. The price will be 1100 rubles.

Advantages:

all sockets are switchable;
straight position of electrical outlets;
child protection system;
warranty period.

Flaws:

There is no protective system against high-frequency interference.

ZIS Pilot Pro GP

Compared to other inexpensive devices, this model is distinguished by good suppression of high-frequency interference and the ability to withstand high voltage. The last option is possible if there is a working grounding, since this function is implemented using a special lightning arrester. The extension cord also has a varistor protection system. As an addition, the device’s ability to indicate connection and the ability to install 2 flat plugs into the network at once are noted.

Along with this, users have had complaints about the strength of the elements and the quality of the product for a long time, which is why the extension cord has a relatively low rating in the rating of surge protectors. A warranty period of 5 years will help increase the attractiveness of the recommended device in the eyes of potential consumers. Costs 1300 rub.

Advantages:

good suppression of high-frequency interference;
effective lightning arrester;
connection indicator;
GP socket;
warranty period.

Flaws:

unreliability of the start key and thermal breaker;
total load 2.2 kV.

Daesung MC2343

So, the first model in our rating will be the Daesung MC2343. This extension cord is equipped with a separate switch for each connector. South Korean manufacturers have thought of another important advantage over their competitors, for example, contact holes located all in one row, which is very convenient when connecting large chargers or external units. In addition, child protection is provided in the form of curtains. There are holes made in the case, they will make it easier to mount the device on the wall.

does not protect against RF interference.

The best filter I have purchased for my home. The quality is top notch. The main advantage is that you can turn off the sockets individually. At first we used one for six months, after justified expectations we ordered a second one. And the cost of this product, complete with such functions, is quite budget-friendly.

How to choose a surge protector for your PC and other devices?

We all understand perfectly well that with large voltage drops, equipment may not be able to withstand it and fail. To avoid this, surge protectors are used. I will write about how to choose a surge protector for home use.

It is better to use surge protectors in any home, since almost everyone has many electrical appliances. They can burn out due to voltage surges, which a person is not always able to notice.

[aesop_image imgwidth=”500px” img=”https://computerinfo.ru/wp-content/uploads/2016/07/setevie_filtri.jpg” align=”center” lightbox=”on” captionposition=”center”]

Why are surge protectors needed?

They are designed to protect against certain types of interference, for example, voltage surges, that is, this means that over a certain period of time the optimal voltage changes. This can happen due to the connection of many powerful devices to the network. Pay close attention to what you connect and what might happen.

Surge protectors can protect equipment from lightning strikes or grounding problems. There is protection against interference that may be caused by other devices located close to each other.

What can surge protectors protect?

I would apply it to any equipment, that is, computers, laptops, other equipment such as refrigerators, televisions and other things. Can also be used for game consoles.

Types of network filters

Although these devices do not differ in appearance, they have a number of characteristics with different levels of protection, which may even imply turning off the equipment to save it.

Here, for example, are filters of the Essential type. The simplest and most inexpensive devices. You can connect cheap or old equipment to them.

Devices of the Home/Office type are already more advanced, as they have increased protection. They can be used at home without any problems.

Finally, the Performance type, already more expensive, but also more secure filters, expensive equipment is connected to them, which are very sensitive to the slightest interference in the network.

There are more expensive surge protectors that have higher protection ratings. If a regular filter can absorb approximately 960 J, but an expensive model can absorb 2500 J. It is clear that the more expensive the filter, the better it will protect.

It is worth noting that such filters are provided if the outlet in the house is grounded. This is not the case in ancient houses, which is why there is less protection. In any case, the equipment must be connected to a surge protector, preferably a good one.

Is the filter a fuse?

The surge protector is very fast because it works before the lightning strikes the house. Circuits located inside the filter quickly analyze what and how to do - dissipate or absorb excess energy. As I wrote above, a more expensive filter will turn off the equipment so that the electrical impulse or interference does not ruin it.

Some filters have a disconnect switch that, in the event of strong interference, simply turns off the filter; it must be turned on again to continue operation. Similar to the principle of a plug on a meter or in an electrical panel.

Cheap filters are like a simple fuse; if interference reaches it, then the surge protector is no longer suitable for use, but it does not protect the devices connected to it well.

Surge filters also have a warranty. Simple models can work for 3 years, and more professional ones up to 5 years, and maybe more. If the device breaks down, the manufacturer must repair it under warranty.

How to choose a surge protector, what to look for?

When choosing a surge protector, you need to highlight several characteristics

First you need to pay attention to the wire. The device must have a fastening so that the cord can be routed normally

This is necessary to avoid a bunch of wires scattered everywhere. There are models in which the wire can be rotated 180 degrees, which allows you to position it as you please.

The cord has lengths, for example, 3 meters, so they are used as an extension cord. Some models have the ability to be attached to a wall.

Surge protectors may have different distances between sockets, so choose depending on what devices you will connect.

You also need to pay attention to the number of sockets, which is very important if you connect few or many devices. It would not be bad if the filter had special curtains that would protect children from unnecessary touches

Filter options

Let's look at the main differences to choose the best one:

number of connected equipment. The number of sockets is far from the main parameter, since the criterion of the maximum power that the device can withstand (measured in kW) should be taken into account;

filtering of additional lines: telephone, network, television;

maximum freely compensating impulse (measured in kJ). The larger the parameter, the larger the voltage surge will be smoothed out and will not reach the protected device;

wire length. The functionality and performance of the compensator does not depend on it, but it is important to consider in advance what length of cable is needed to connect the devices;

thermal breaker – protection against overheating, very useful for constantly compensating for surges in thermal energy;

power. If it must be possible to connect multiple equipment simultaneously, it is necessary to select a compensator with a rated load current of at least 10A.

pulse interference current or maximum possible current. At an average load it should be in the range of 3.5-10 kA.

Types of stabilizers can be divided according to the level of protection and operating principle:

basic - the simplest type of voltage filters, suitable for low-power home appliances;

advanced (medium) - the most popular type, they have some additional functions and sometimes a couple of network protection ports;

professional - expensive filters with maximum protection.

The difference between them is the price: the higher the level, the more complex and expensive the compensation board. Mid-level devices can absorb up to 960 joules, and professional ones - no less than 2500.

However, it is worth considering that the effectiveness of protection strongly depends on the grounding capacity of the outlets. For example, in old houses where there is no grounding in the electrical network or it is poor, pulse stabilization drops tenfold, and sometimes becomes completely useless. That is, they can provide some protection, but there is no need to purchase a professional compensator.

Stabilizer: normal flight

Unlike a network filter, which smoothes out pulsed and high-frequency distortions (interference) by passive means, a network stabilizer actively influences the key parameter of the power supply - voltage, compensating for its deviations. Until recently, in Russia, the norm for a single-phase network was considered to be 220 V ±10% (GOST 5651-89), that is, any AC voltage in the range from 198 to 244 volts was considered normal. Recently, the interstate standard GOST 29322-2014 (IEC 60038:2009), brought into line with European standards, has come into force, according to which the standard mains voltage is 230 V ±10%, or from 207 to 253 V. The good old 220 V, however, for now no one has canceled it - the standards operate in parallel, so in general you can take into account the approximate range of 200-250 V. Almost all modern computer and consumer electronics are equipped with switching power supplies, which themselves are excellent stabilizers and are capable of operating in a wide range of supply voltages. For example, the vast majority of computer power supplies - both built into PCs and external ones, for laptops and tablets - are designed for global use in most countries of the world with a rated network voltage of 110 V to 240 V. In some cases, such equipment “starts “even with a voltage of only 90-100 V. Accordingly, a decrease in voltage in the outlet for any reason is not a hindrance for them; increasing compensation occurs automatically. With increased voltage it is a little more complicated: even the most modern electronics are designed for a maximum of 250-260 V, but if for some reason such voltage in the supply network has become the norm (in urban conditions this is hard to believe), of course, it is better to stabilize it by external means. Regardless of high or low voltage, all lovers of warm tube sound - rare vinyl turntables, players, amplifiers and other ancient equipment - fall into a special risk group. In this case, the use of stabilizers, as they say, is not discussed. Currently, the most popular and numerous representatives of the class of household voltage stabilizers are electronic, where the incoming current with a frequency of 50 Hz is converted into high-frequency pulses with a frequency of tens of kilohertz and controlled using pulse-width modulation (PWM). Of the significant disadvantages of such stabilizers, one can only note that the sinusoid at the output of such stabilizers is far from ideal. The list of advantages is much longer: compactness, light weight, huge operating range, versatility, resistance to overloads, and, most importantly, an incredibly affordable price. In addition, in retail you can also occasionally find “classics”: impressively sized blocks that stepwise reduce or increase the output voltage due to electronic or relay switching of the windings of a full-fledged autotransformer located inside. Such stabilizers are bulky, have a fair amount of weight, but practically do not distort the input current sinusoid. As a rule, stabilizers of this class are aimed at powering an entire house or performing a specific task - such as powering a gas boiler, however, under certain conditions, such a device may be the ideal choice for an audiophile. A good stabilizer, as a rule, is equipped with all the passive filters characteristic of surge protectors, and also has all conceivable types of protection, including overvoltage, overload, overheating, short circuit, etc.

Features of choosing network filters

The first step is to decide what type of surge protector you need. Let's start with the classic models. The simplest one consists of a Euro-plug, an extension cord and a block itself with sockets for Euro-plugs and an on-off button. In this segment, the choice is made according to the following criteria:

the number of sockets on the block (estimate how many consumers will be simultaneously connected to your surge protector, and leave 1-2 in reserve);
length of the extension wire (approximately calculate the distance to the place where the device will be installed, and add a few centimeters so that the wire does not run under tension);
output power (each surge protector has a maximum power that it can withstand; in case it is exceeded, there is a well-thought-out protection system. We do not recommend connecting large consumers like an electric kettle through it, although there are devices for such purposes).

Also recently, surge protectors with USB connectors have been gaining popularity. Nowadays, more and more electrical appliances work through this interface, and the ability to charge your phone with just one cable is also very convenient. In this segment, in addition to the above, several more aspects are added:

number of Universal Serial Bus slots (similar to sockets - it’s better to have 1-2 spare);
output current via USB (a very important indicator if you are going to charge the phone using your filter: the higher the current, the faster it is powered).

What to look for when choosing a surge protector

Let's consider the main parameters of network filters that you should focus on:

Network wire length. The most common values are 1.9 and 3.1; in more rare cases, a wire up to 5 meters long is used.
The size of the wire cross-section. The best option is 0.75 mm2 or 1 mm2, suitable for a load of 10 amperes, which is what most surge protectors are designed to support.
At what current value does the thermal fuse trip? Most manufacturers set the maximum permissible current value to 10A. Depending on the size of the overload and the response time, the fuse may trip at values in the range of 12-16 amperes.
How much energy can varistors dissipate without breaking down? In particular, this parameter is affected by the dimensions of the element. The most commonly used varistors are with diameters from 8 to 18 mm.
How many fuses are there in the device? In addition to the thermal fuse, a fast-acting fuse based on metal-organic semiconductors can be installed, plus the manufacturer can install a fuse in the neutral circuit.
The presence of additional elements of the device, such as an LED indicator that stops working if the safety elements burn out, and a gas discharger. Surge protectors also include USB ports through which you can charge gadgets without using an adapter.
The capacity of capacitors that filter the electrical current of the network from interference.
The presence or absence of a hanger, usually represented by holes in the surge protector housing.
Number of sockets and their type. The number of sockets usually varies from 4 to 6, most often there are 5 places for plugs in the case. In accordance with modern standards, the network uses Euro sockets with grounding. You can purchase models with one universal socket without grounding, in which you can use any plug.

Basic parameters of network filters

IEK WFP10-16-03-01-N

The surge protector IEK WFP10-16-03-01-N is designed for three sockets. This device is designed for a maximum load of up to 3500 W at a mains voltage of up to 250 V and a rated current of 16 A. The cable length is only 1.5 meters. The manufacturer has provided grounding and a switch button; the surge protector also has a light indication. The device uses an IPS wire consisting of 3 cores, its cross-section is 1 mm, and the degree of protection of the device is IP20. The model is made in white color. It has a classic minimalist design that fits well with modern interior design.

Advantages

High level of maximum load;
Availability of an indication button and a grounding system;
Reliable VPS wire;
Attractive appearance.

Flaws

Short cable length;
Not the lowest cost.

Due to the fact that the surge protector is made in white, it does not fit well with classic interiors. In terms of functionality, the device does not cause any problems for users.

APC surge protectors

8 devices can be connected at a time to this device, which is equipped with protection for a computer network, telephone and video lines, a high-frequency interference filter and a three-meter cord. The APC surge protector has an attractive design. A nice addition to the main product are 3 cords. They are designed to connect to the Internet, telephone and TV. On the case there is a button to turn off the device and indicators showing grounding, connection and the presence of network overloads, next to it there is a communication line protection unit.

The device is thought out to the smallest detail. Wall mounting is possible in any position. There are feet for using it on the floor. Based on the positive reviews from experts, it is clear that this is a unit of the highest standard, capable of satisfying the majority of consumers. All functions declared by the manufacturer are performed with honor. Despite all its advantages, this unit does not have local network grounding. The surge protector, the price of which is higher than that of SVEN Fort Pro, is better in both performance and workmanship. The disadvantages found by consumers include the inconvenience of mounting in a horizontal position.

ExeGate SP-3-1.8W

The surge protector is absolutely no different in design from many others. It is designed for three sockets. The ExeGate SP-3-1.8W model is made in white color, having 1 red switch on the body with an operation indication function. The manufacturer has provided a grounding system and a cable 1.8 meters long, plus the maximum load for which the surge protector is designed is 2200 W. Additionally, it is also worth paying attention to the fact that the device has the function of protecting electrical appliances from short circuits and overheating, and prevents the adverse effects of high-voltage discharges and impulse noise on household devices.

Advantages

Classic appearance;
Reliable protection of household appliances;
Operation indication function;
Availability of grounding.

Flaws

Completely ordinary design;
Not very long cable length.

Despite the fact that this model is practically no different from many others in its technical parameters, it is popular. Reviews on the Internet say that this is due, first of all, to the affordable cost of the surge protector.

Features of choice

The choice of device model depends, first of all, on the buyer, as well as where it will be used, for what purposes and devices.

Home electrical systems don't have huge power surges or high-tech interference. Therefore, it is enough to take medium-type equipment: not too expensive, but not the smallest and cheapest.

Before you buy a surge protector, you need to calculate:

the number of required sockets and the required power, based on the number of connected devices;
cable length;
wishes for filtering additional ports (phone, network).

When choosing a voltage stabilizer for an office or several powerful equipment (for example, a widescreen TV and a gaming computer), you need to take into account production requirements, such as:

amount of equipment;
probability of interference and its power;
amplitude of voltage surges.

It is not recommended to save on a voltage compensator for the office. Read the review and choose the most suitable model, since one failure can cause a production stop due to the failure of the entire system or lack of access to the server machine.

How to choose a surge protector for a computer and laptop

Many, when purchasing a laptop, all-in-one computer or desktop computer, do not forget to purchase a pilot filter, and do the right thing. Expensive equipment can break down as a result of network surges, so it must be protected from breakage.

When choosing a filter to protect your laptop and computer, you need to look at such primary points as:

number of sockets,
wire length,
presence of a power button and indicator light.

The standard length is 180 cm, but if you wish, you can look for models with a cord of 3 and 5 m. The longer the cord, the more practical it is to use, and in the office it will be more convenient to have a short cord so that it does not get tangled under your feet.

If the length of the wire turns out to be shorter than what the manufacturer stated, the other qualities of the device may also be questioned, and it is better to refuse to purchase this device.

Of course, the device must be powerful, that is, it must be enough for all the devices that you plan to connect to it.

It will be convenient to have an off and on button so that you don’t have to unplug the cord from the outlet every time, especially if it is located in a hard-to-reach place. The light will indicate whether the device is turned on or not.

There should be enough sockets for all devices: router, printer, monitor, scanner, so that you don’t have to purchase additional extension cords that do not serve as a surge protector. Also check the distance between the sockets - it should be enough to conveniently connect several devices at once.

A mount for wires is also useful; it will be useful if there are a lot of wires and you don’t want them to get tangled. This “item” is optional, but will be convenient to use.

It is worth keeping in mind that no network filter will provide complete protection of your computer from network surges. Only an uninterruptible power supply or voltage stabilizer can cope with such a task.

It is important to pay attention to such characteristics as the maximum current - this indicator must be at least 10 A, as well as the energy of the surge - in expensive filters it can reach several thousand J. If you have children, it is worth purchasing models with special curtains

If you have children, it is worth purchasing models with special curtains.

Also, if you plan to mount the device to the wall, immediately purchase a filter with such a mount.

Make sure the filter has a sufficient warranty period. Reliable manufacturers usually provide a guarantee for their products for up to 5 years.

You should not buy cheap devices of dubious manufacture. It’s better to spend money once and buy a high-quality, reliable filter.

VIDEO INSTRUCTION

If you have a laptop

As for laptops, they are equipped with rechargeable batteries that can partially smooth out power surges. But even if you have a battery, it is recommended to purchase a surge protector, since batteries can behave unpredictably.

They especially do not like it when they are not turned off from the network and at the same time turn off the laptop. If you forget or don't want to unplug the plug from the socket every time, use a surge protector.

In order for the surge protector to work properly, no other devices, such as an iron or kettle, should be connected to the device. The outlet must also be grounded. Unfortunately, this is not always the case in older houses.

Do you need a surge protector for your TV?

The question of whether to install a filter for a TV is quite controversial among experts. Many people believe that if the electricity in your home is not turned off, then you can do without this device. But are there many such houses in our country?

After all, even in the capital, power outages are not uncommon. This means that you should take care of purchasing a network noise suppression filter. Uninterruptible power supply will help extend the service life of equipment when turned off and on for an hour.

An inexpensive 250-watt model will be enough to install at home. It is enough for stable operation of a regular 130 Watt TV, taking into account the router and receiver.

The cost of such a device will fluctuate around two thousand rubles, which is much cheaper than repairing equipment in the event of a breakdown. If there are regular problems with electricity in the house, it is worth purchasing a powerful uninterruptible power supply that can work for a long time.

For LCD TVs, it is recommended to install stabilizers selected for the voltage of your particular outlet. As a rule, conventional surge protectors are not able to protect expensive LCD TVs from damage; only stabilizers can do this.
