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 measurement, voltage measurement accuracy ‚ȧ1%.Measuring frequency 45Hz-65Hz,knob setting, LED indicator shows working status. Rated voltage three-phase there wire 220V~460V universal. DIN rail mounting.
