2500-600
The Model 2500 3-Phase Monitor is designed to continuously monitor 3-phase power lines for abnormal conditions. This device features solid-state voltage and phase-angle sensing circuits, which drive a SPDT electromechanical output relay.When the correct voltage and phase sequence is applied to a specified Model 2500, the output relay will not energize. An under voltage, phase reversal, phase unbalance or phase loss condition will cause the output relay to energize, even if regenerated voltage is present. Complete power loss will not cause Model 2500 to trip. The 2501 version of this unit operates in fail-safe mode, and the contacts de-energize on a fault condition. A neutral connection is not required, allowing the Model 2500 or 2501 to be used with either Wye or Delta system configurations.
Each option on the Model 2500 or 2501 monitor is adjustable throughout its 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.
Seven versions of the Model 2500 or 2501 cover voltage ranges from 120 to 600 VAC, and are UL Listed and CSA Certified.

2500D-600
The Model 2500D 3-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 DPDT electromechanical
output relay. Connect to any 3-phase WYE or DELTA with no neutral connection required.When the correct voltage and phase sequence is applied, the output relay will not energize. An under voltage, phase reversal, phase unbalance or phase loss condition will cause the output relay to energize, even if regenerated voltage is present. Complete power loss will not cause the Model 2500D to trip.
