voltage relay rele de voltaje

Voltage control relay(Made in China)

1. Applications

Used in air conditioning units, elevator machine room, pumps, fans and other motor control applications, as protection of over-voltage, under voltage, phase failure, phase sequence and phase unbalance. When the power supply is abnormal, turn off power supply to protect the equipment.

2. Features 

Built-in microprocessors, true RMS voltage measurement, voltage measurement accuracy ≤1%. 50/60Hz universal, Knob setting, LED indicator shows working status. With N-phase phase failureprotection. DIN rail mounting.
