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.
1. Convenient Monitoring: The voltage relay can monitor its own operating voltage (true rms measurement).
2. Application: Equipment protection and control (tower cranes, elevators, agricultural equipment, refrigerated trucks); prevent reverse operation of equipment; normal/emergency power switch; prevent phase failure of dynamic loads.
3. LED Indicator: The working status of the voltage control relay is indicated by the LED indicator.
4. Small Size and Easy to Install: The voltage protection relay is ultra-small and can be mounted on a 35mm DIN rail.
