Detail Information

Function

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 5 1%. Measuring frequency 45Hz~65Hz, 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 failureprotection. DIN rail mounting.
