Rated supply frequency 50/60Hz Measuring range AC 166V -528V ; AC 96V- 329V Measurement frequency range 45Hz~65Hz voltage threshold range 2%~ 20% Phase failure and phase sequence <0.5s Action delay range 0.1s~10s Reset delay range 0.1s~10s Rated insulation voltage 440V Voltage measurement ≤0.1% Update Time 2020-04-04 Detail InformationFunction
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.
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.
