This is a voltage protection device designed to safeguard motor-driven appliances such as refrigerators, freezers, and coolers from damage caused by power fluctuations.
Function: It protects appliances from low voltage (brownouts), high voltage, spikes, and surges.
Mechanism: The device disconnects the power supply to the appliance when the voltage goes outside of a safe range. It has a built-in delay timer that ensures the power supply is stable before reconnecting, which helps protect the compressor.
Indicators: The lights on the front indicate the status of the power supply:
OFF: No power is being supplied.
WAIT: The device is waiting for the power to stabilize before reconnecting.
ON: The power is stable, and the appliance is receiving electricity.
