Voltage regulator URZ3437-25 manufactured by KEMOT with input voltage from 230 to 400 VAC and output power 25000 VA. Voltage stabilizers provide constant and stable voltage in the power grid if it is higher or lower than standard and ensure normal operation and protection of electrical appliances.
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.
