SLU-0201 Universal Three Phase Voltage Monitoring Relay

Model SLU-0201 universal three phase phase voltage monitoring relay from the ATC Diversified Electronics Division of Marsh Bellofram Corporation provides cost effective protection against premature equipment failure caused by voltage faults on 3-Phase systems (Wye or Delta).

This unit can be easily adjusted for voltage, imbalance percentage and time delay requirements to protect against unbalanced voltages or single phasing regardless of any regenerative voltages. Unique features of the SLU-0201 includes auto-ranging scales (200-500v 3 phase), adjustable restart delay, adjustable fault delay, automatic reset, rapid cycle lockout and a bi-colored led for additional diagnostics.

Typical applications for the Model SLU-0201 universal three phase phase voltage monitoring relay include municipal water treatment plants, sewage plants (water and wastewater), booster stations, grinders, irrigation, petrochemical, machine tool, conveyors, HVAC, elevators, utilities, processing equipment, agricultural machinery and equipment.
