Short Description:

Voltage protection relay uses a high-speed and low-power processor

as its core. When the power supply line has over-voltage, under-voltage

, or phase failure, phase reverse, the relay will cut off the circuit quickly

and safely to avoid accidents caused by abnormal voltage being sent to

the terminal appliance. When the voltage returns to the normal value,

the relay will turn on the circuit automatically to ensure the normal operation

of the terminal electrical appliances under unattended conditions
