Diversified Electronics 3 Phase Universal Monitor Relay

Phase Monitor Relays (3-Phase Monitors) provide cost-effective protection against premature equipment failure caused by voltage faults on 3-Phase systems (Wye or Delta). Until recently, different phase monitors were required to address voltage range and protection requirements for each individual power and motor circuit. The SLU Series multimode phase monitoring relay, was designed for the convenience of electricians, maintenance managers and engineers. A single SLU Phase Monitoring Relay can be easily adjusted for the voltage, imbalance percentage and time delay requirements to protect against unbalanced voltages or single phasing regardless of any regenerative voltages. Both Delta and Wye systems may be monitored. In Wye systems, connections to neutral are not required.
