Domestic, electromechanical

Voltage stabilizers allow maintaining the voltage level in the room, so that the jumps that can reach several tens of volts do not have a negative effect on electrical appliances. Depending on the type, specialization and conditions of application, the device can cost 4000-6000 rubles. Stabilizers are industrial and domestic, electromechanical, relay, symistor, double transformation and with a wide-pulse modulation.
