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. LCD displays voltage and fault information, protection can be turned on or off. Check 3-phase voltage value by knob, with counting and timing function. Record number and time of using devices. DIN rail mounting.
