The AVR-500VA mainline voltage stabilizer combines the features of 2 devices: a voltage regulator and a surge protector.
The main function is the automatic regulation of the voltage supplied at the input of the stabilizer. The device improves the parameters of the voltage from the local mains or a power generator. It also suppresses interference introduced to the mains by other devices.
Unexpected voltage spikes (too low or too high voltage) can be dangerous for various types of equipment operating in the mains, including: household appliances and electronics, computers, heat pumps. The AVR stabilizer stabilizes the voltage from the mains so that the output is within the range of energy standards and thus safe for all equipment connected to it.
