Voltage stabilizers are used to ensure normal power supply and operation of household appliances, refrigerator, air conditioner, etc. The voltage stabilizer is built by toroidal autotransformer, contact regulator - servo motor, actuator, control and protection board. When the input voltage is not accurate, the motor of the electrical stabilizer drives the arm of the contact regulator and provides a stabilized output voltage. It is good when buying a voltage stabilizer, it should have high accuracy, short correction time, small self-consumption, long-term reliable operation. The electrical stabilizer can be equipped with various protections - delayed start after voltage drop, protection from increased or decreased input voltage, overload protection with automatic fuses with "C" curve, etc.
This voltage stabilizer is particularly suited to stabilize the voltage in electrical circuits incorporating pellet burners up to 1500 W. Due to high starting currents and reduced voltage at certain offshore parts of the grid, the pellet burner is a special load and requires a large reserve Of power, so a stabilizer with a power rating of 5000 watts is needed. Also, a stabilized UPS can not be switched on before the stabilizer because the transformer is saturated, overheated and damaged when the voltage drops.
If these conditions are not met, the stabilizer may be overloaded and damaged and the warranty will not cover the damage.
