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 microprocessor, true RMS measurement, voltage measurement accuracy <1%。Measuring frequency 45Hz~65Hz button setting, LCD display voltage and fault information can be turned on or off.Check phase voltage value by button, With N-phase phase failureprotection, DIN rail mounting.
