Product Description

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.
 
Features:
Built-in microprocessors, true RMS voltage measurement, voltage measurement accuracy  ≤1%.Measuring frequency 45Hz~64Hz,button setting, LCD display voltage and fault information, protection can be turned on or off. Check phase voltage value by button, with N-phase phase failure protection, DIN rail mounting.
