Applications
Used in air conditioning units, elevator machine room, pumps, fans and other motor control applications, as protection of over-volltage, 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 acduracy ≤1%. Measuring frequency 45Hz~64Hz, button setting, LCD display voltage and fault information, protection can be rurned on or off. Check phase voltage balue by button, with N-phase phase failureprotection, DIN rail mounting.
