Voltage Control Relay

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 loss, phase sequence, 3-phase imbalance. When the power supply is abnormal, stop supply to protect the equipment.

2. Features 

Built-in microprocessors, true RMS measurement, voltage measurement accuracy ≤ 1%. 50/60Hz universal, knob setting. LED indicator shows working status. Rated voltage three-phase three-wire 220V~460V universal. DIN-rail mounting.
