Product Description3-phase monitors are designed to continuously monitor the voltages of a 3-phase power distribution system for abnormal conditions. The monitors feature solid-state voltage and phase angle sensing circuits which drive a SPDT electromechanical output relay. A neutral connection is not required. This allows each model to be connected to any three phase WYE or DELTA configured power distribution system. When the correct voltage and phase sequence is applied, the output relay will energize. An under voltage, phase reversal, phase unbalance, or phase loss condition will cause the output relay to de-energize. Each option is adjustable throughout it’s operating range. The adjustment pots and LED indicators for Voltage adjust, unbalance adjust and time delay are mounted on the front of the unit, for easy access. UL Listed to U.S. and Canadian safety standards.
