Description
Time Mark 2501-480 3-Phase Monitor
 |
|
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 its 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.
