All about Sven surge protectors and extension cords

An unstable voltage can be the fault of the electricity company, old wiring, or neighbors that include equipment that could cause a short circuit. A surge protector will help reduce the risk of equipment breakdowns due to power surges.

The Sven surge protector is a budget device that well protects household appliances from sudden power outages or power outages. In addition, it is equipped with the functions of filtering and eliminating negative impulses and interference that can harm equipment.

The device includes a case and a cord. Elements with protective functions are located inside the housing. The outer side of the device is represented by sockets, the number of which ranges from 1 to 8.

To connect the elements of a personal computer - a system unit, a monitor, speakers and a printer, a number of sockets are required. In this case, you can use a regular extension cord, which has several sockets, but it will not protect the devices from voltage surges in any way.

The manufacturer indicates the input voltage on each of the devices, and this information must be in accordance with the characteristics of the electrical network. In this case, various failures and jumps are not taken into account. Stabilizing the voltage of the current going to the equipment is the main task of the filter. The maximum power consumption of the devices is of great importance; it should not exceed the indicator passed by the filter.

The Sven filter range is represented by the following options.

The device has 5 sockets, 2 USB connectors for recharging some devices. The body of this variant is made of durable, shock-resistant material with the highest degree of fire safety. There is a switch with an indicator. The device provides protection against voltage fluctuations. The filter can be fixed in any position on the wall. The color of Sven SF-05L is white and black.

The model has 2 USB connectors, which provide the ability to recharge various devices with a maximum power of 12 W and simultaneously connect 2 devices with a current of 2.4 A. 16.

The main characteristic feature of the filters of this brand is the reliable contact of these plugs even after prolonged use. This version of the line filter makes it possible to smooth out high-frequency interference with an energy of 125 Joules. The product is made of shock-resistant material. The presence of protective curtains provide even greater protection against the ingress of foreign particles.

It is a product with a two-pole switch with an illuminated on indicator. Protects against noise and interference from the mains supply. In addition, it has varistor protection against high-voltage discharges. There are 8 multifunctional sockets with grounding, automatic thermal fuse. It is possible to fix the filter on the wall regardless of its location.

A device with a two-pole switch with an indicator light for switching on. The main function of the filter is to protect against noise and various interference from the power supply.There is a varistor protection against high voltage discharges. There are 5 multifunction outlets, each with its own switch. The size of the cord is 180 cm / 300 cm / 500 cm. The product is made of material that does not undergo combustion processes.

Model with the highest amperage of 1 A. There is a two-pole switch with an on indicator light. The main function is to protect against noise and interference from the mains supply. Also, the product is capable of providing a high degree of protection against high-voltage discharges.

In the presence of 8 multifunctional sockets with grounding. There is an automatic thermal fuse. The product has a body, resistant to physical influences, made of material that is not subject to combustion. The conductor is made of copper, no impurities.

It is a product with powerful varistors that protect against impulse noise. The filter has one outlet with a protective shutter that prevents foreign objects from entering. Equipped with an automatic fuse that turns off devices in case of network overloads and short circuits. The product is presented in black and gray and is equipped with a 5 m cord.

The device with a double switch for the light indication of inclusion. Has varistor protection against high-voltage discharges. The presence of input sockets is characteristic, the design of which makes it possible to connect both plugs of domestic technology and products of European countries. There is a possibility of fixing on the wall, regardless of the location.

It is a model with a voltmeter. The product can attenuate impulse noise by 10 times. The body of the device is black, made of non-combustible material. The cord of the product is 5 meters.

When choosing a surge protector, you need to take into account its characteristics and parameters. According to the purpose and degree of protection of household appliances, surge protectors can be of the following options.

• For household use. Such devices are called "basic" because they have a fairly simple structure and a low set of safety factors. These filters are easy to identify visually. They have a small number of outlets, a miniature body and a short cord. The products are well suited for home use.
• For advanced users. This type of filter is a safe and practical option for connecting multiple personal computers. Filters can be used both at home and in the office. The product has a rather long cable and a large number of outlets, which makes it seem bulky.
• Professional products. They are indispensable for devices with a high price and increased sensitivity. They allow you to ensure the safety of equipment to the maximum. The filters are characterized by a long cord and three-phase sockets.

It is not difficult to find a good high quality filter if you follow certain selection rules.

• Pay attention to the dimensions of the product. A small size and flat filter can be a low-quality copy that has no protective properties. If you have the slightest doubt, you should ask the seller for documentation. If it contains technical features and parameters, then the model is original.
• It is preferable to purchase a product with sockets suitable for Euro-type plugs. These products are compatible with various types of devices.
• It is better to choose products with USB.

Models equipped with a remote control are also available. They are well suited for those who do not want to use manual controls.
