Engineered and Built in the USA
2501D-380
Categories: 3-Phase-Monitors, 2501D-SeriesThe Model 2501D 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 energize. An under voltage, phase reversal, phase unbalance, or phase loss condition will cause the output relay to de-energize.

3-Phase Monitor with Trip and Restart DelaysSelect optionsThe Model 19 continuously monitors 3-phase power lines for abnormal conditions. When properly adjusted, the Model 19 monitor will detect phase loss on a loaded motor even when regenerated voltage is present.
This device consists of a microcontroller with a voltage and phase-angle sensing circuit, driving an electromechanical relay. When correct voltage and phase rotation are applied, the internal relay will energize. A fault condition will de-energize the relay. When the fault is corrected, the monitor will automatically reset. An adjustable restart delay prevents short cycling in compressor applications and an adjustable trip delay prevents nuisance tripping during power fluctuations.
The Model 19 does not require a neutral connection and can be used with Wye or Delta systems. Voltage ranges are sufficiently wide to allow for proper adjustment to existing conditions. Both FAULT and NORM condition indicators are provided to aid in adjustment and system trouble-shooting. The Model 19 is UL Recognized in the U.S. and Canada and is available with optional gold flashed silver contacts for low current applications.
