The best surge protector for PC and household appliances

At the moment, the surge protector can be found in almost every office space, apartments, private houses. Therefore, the choice of a quality extension cord for many becomes a big problem. To help with the purchase of the device, a rating of the best devices was compiled.

What to look for when choosing a power supply filter

Before you buy such a device, it is recommended to study its most important indicators. They directly affect the life of the device, the reliability and performance of the device.

Number of Outlets

The number of electrical outlets, taking into account the filter model, ranges from 1-8. With an increase in this indicator, the number of equipment connected to the device increases, but at the same time the mass, size and price become larger.

When choosing the best product, you need to take into account the number of devices that the consumer usually uses. For a computer, it is advisable to focus on extension cords with 5 outlets (power supply, screen, speakers, printer, scanner or router).

Important! Such devices are equipped with electrical outlets with or without grounding. A number of electrical appliances will need grounding (including washing machines), for some they will not.You must find out in the instructions for the extension cord. Do not ignore the recommendations for grounding, as this leads to electric shocks.

Number of power outlets

Distance between sockets

At first glance, the distance between the outlets is the same in each extension cord. When each outlet is occupied by power consumers, and you need to connect an additional power supply, the output wires from the outlets will interfere with the installation of the adapter. For such situations, it is recommended to use filters with a housing that has oversized dimensions. It will occupy more space, but will become necessary in such cases.

Rated current

The highest load determines the filter, which is necessary for a particular situation. This indicator is measured in amperes, for example, for a 220 V device with a maximum power of 2200 W, the maximum current will be 10 A. For a proper device selection, it is necessary to summarize the current values ​​of each connected load, taking into account a certain margin. A device is purchased with a characteristic of at least 10 A.

Important! Emphasis is placed on the maximum pulse current. Devices that are designed for 4000-10000 A are selected.

Power cord length

Among the devices you can find devices with a wire length of 1 to 50 m. It is not recommended to look for a large cord length; in a small room for a computer, printer, phone, an extension cord with a wire of 1.5-2 m is enough. If the power outlet is located far from equipment, then pay attention to the elongated versions (10-50 m).

The longer the cord, the farther the plug-in filter is from the network, but an excessively long cable will complicate the use and movement of the extension cord. A long wire will increase the cost of the device. Therefore, when choosing the length of the cable, it is worth focusing on a specific case. It is recommended to buy an extension cord with a wire length of 2 m.

Additional network filter options

Surge protectors are sometimes equipped with several additional functions that are not particularly significant, but can be useful:

• Microcontroller There is a built-in timer to turn on / off the voltage over time.
• Protection of each power line individually. Such devices cost more, in front of all outlets there is an own switch with a fuse, which guarantees protection. It is recommended to use several devices of various types during operation.
• Protective system against dust, sudden start.
• A latch that secures the wiring. The simultaneous connection of several devices to the filter forms tangled bundles of wires. The latch will help to put everything in order.

DAESUNG MC2343

DAESUNG MC2343

A comfortable, energy-efficient device with separate switches for electrical outlets. It provides protection against sudden voltage surges. A device from a developer from South Korea has another advantage over analogues: the contact holes of each outlet on the device are located in 1 line, which is useful if there are dimensional external power supplies or chargers. Each switch is opened by 2 power wires; a child-proof system is provided. The price will be 1100 p.

Advantages:

• all sockets are switchable;
• direct position of electrical outlets;
• protective system against children;
• warranty period.

Disadvantages:

• there is no protective system against high-frequency interference.

ZIS Pilot Pro GP

ZIS Pilot Pro GP

Compared to other low-cost devices, this model is characterized by good suppression of high-frequency interference, the option of resisting high voltage. The last option is possible if there is a working ground, since such a function is realized by means of a special lightning arrester. A varistor protection system is also present on the extension cord. As an addition, the ability of the device to indicate connection, the ability to mount 2 flat plugs at once to the network, is noted.

Along with this, for a long time the users had complaints about the strength of the elements and the quality of the product, which is why the extension cord has a relatively low rating in the rating of network filters. A guarantee period of 5 years will help increase the attractiveness of the recommended device in the eyes of potential consumers. It costs 1300 p.

Advantages:

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

Disadvantages:

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

The best surge protectors for computer networks

APC PNET1GB

APC PNET1GB

The device is a special surge suppressor. Only in these devices all 8 Ethernet lines are protected. The contacts will be broken after 1 voltage surge, and such a design feature will not actually affect the speed indicators of the communication channel.

It is worth considering that the extension cord will not be able to save from direct lightning strikes, however, it can withstand induced pulses in the state when it is connected to the proper ground. It costs 1,500 p.

Advantages:

• effective Ethernet protection system;

RN-101M

RN-101M

Extension cords for this purpose are recommended to be installed in the panel in the apartment, however, there are situations when a mobile relay is more preferable. For example, when the voltage fluctuates in a wide range, it will not be possible to normalize it in an official way, and the protection of an extremely sensitive technique is necessary. Such devices include old refrigerators that need a delayed restart after turning off the compressor.

Such an extension cord will allow you to adjust the delay of the secondary start in extremely large ranges (up to a quarter of an hour). Effective will be the ability to respond with varying speed to medium and large voltage drops for the initial indicators. The device effectively counters high frequency and other interference (if there is grounding). Price 2500 r.
