Unstable voltage may be due to the fault of the company supplying electricity, old wiring or neighbors, including techniques, the work of which can entail a short circuit. Reduce the danger of breakdowns due to voltage jumps will help a network filter.
SVEN network filter – a budgetary device that protects the household appliances from sharply emerging voltage interruptions or electrical power failures. In addition, it is equipped with filtering and elimination of negative pulses and interference, which are able to harm technique.
The device includes housing and cord. Elements having protective functions are inside the case. The external 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, monitor, speakers and printer, a number of outlets are required. In this case, you can use a conventional extension, which has several nests, but it will not protect the devices from voltage drops.
The manufacturer on each of the devices indicates the incoming voltage, 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. Stabilize the voltage of the current coming to the technique – the main task of the filter. Much significance is most consumed by the power of the instruments, it should not be greater than the filter transmitted.
SVEN network filter has a concise appearance. It is possible to fix the device on the wall.
SVEN filters model range are submitted by the following options.
The device has 5 sockets, 2 USB connector for recharging some devices. The case of this option is made of a solid, starry stard of material with a maximum degree of fire safety.

Criterias of choice
Selecting a network filter, you need to take into account its characteristics and parameters. For appointment and degree of household appliances protection Network filters may be the following options.
- For domestic use. Such instruments are the name “basic”, because they have a fairly simple structure and a low set of prevention coefficients. Such filters are easy to determine visually. They have a small number of outlets, miniature housing and unallone cord. Products are well suited for use at home.
- For experienced users. This type of filter is a secure and practical option that is suitable 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, from which it seems bulky.
- Professional products. They are simply necessary for devices that distinguish high price and increased sensitivity. Allow for the safety of technology to the maximum. Filters are characterized by the presence of a long cord and three-phase sockets.
It is easy to choose a good high quality filter if you follow certain selection rules.
- You should pay attention to the size of the product. Small sizes and a flat filter can be a base copy that has no protective properties. In the event of the slightest doubt, it is worth asking the seller’s documentation. If it contains technical features and parameters, then the original model.
- It is preferable to acquire a product with sockets suitable for eurotip forks. Such products are compatible with devices of various species.
- It is better to choose products with USB.
Also available models equipped with a remote control. They are well suited for those who do not want to use manual control.
