How to buy a voltage stabilizer correctly?
By the type of networks, stabilizers can be divided into single-phase, designed for a voltage of 220V and three-phase, which are designed for 380V. Voltage stabilizers, which are designed to work with low and medium power, are devices that are installed directly in front of devices: a computer, TV, washing machine, refrigerator.
Nowadays, a voltage stabilizer for the home is used more and more often, and the choice here is growing, more details can be found on the website
http://www.phantom-stab.ru . A single-phase type of appliance, which is intended for the home, has a power slightly more than household stabilizers for individual equipment. Such devices are installed at the entrance of the electrical wiring into the room (house, apartment, cottage), this allows you to maintain this voltage at the same level.
For a country house, cottage, summer residence, a three-phase power supply network is often used. In this case, a household three-phase stabilizer is used, you can buy it here

To calculate the power correctly, you need to find out the total power of the devices that will be present in the house, and be powered by a stabilizer. Then add 20-25% as a reserve. Indicators of electrical consumer devices can be obtained from the passport data.
You can make a choice, delivery and purchase using the Internet. It will be enough to find a special website and place an order with further payment. You need to choose a stabilizer for your home so that it meets the characteristics:
Operating voltage range of heating equipment. Appliances for household use operate from 220V;
The power consumed by the system. The system includes many devices, the power of which should be taken into account;
Mains voltage. It is necessary to clearly define the operating voltage range;
As for voltage stabilizers, they must be easy to operate, have a convenient appearance, and not create noise during operation.
