Applications of ZHRV5-45 Voltage control relay


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.

Features of ZHRV5-45 Voltage control relay

Built-in microprocessors, true RMS voltage measurement, voltage measurement accuracy≤1%. Measuring frequency 45Hz~65Hz,knob sets, LCD displays voltage and fault information, protection can be turned on or off. Check the 3-phase voltage value by button,with the counting and timing function. Record the number and time of using devices.DIN rail mounting.
