DESCRIPTION

The Models 2500 and 2501 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 SPDT electromechanical

output relay. A neutral connection is not required with either

the Model 2500 or 2501. 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 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.

When the correct voltage and phase sequence is applied to

a specified Model 2501, 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 on the Model 2500 or 2501 is adjustable

throughout it’s operating range. The adjustment pots and

L E D indicators for VOLTAGE ADJUST, UNBALANCE

ADJUST and TIME DELAY are mounted on the front of the

unit, for easy access .

Seven versions of both the Model 2500 and the Model 2501

cover voltage ranges from 120 to 600 VAC. All models are

UL Listed to U.S. and Canadian safety standards.
