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