Engineered and Built in the USA
B2652
Categories: 2652-Series, 3-Phase-MonitorsThe Model 2652 3-Phase Monitor is designed to protect motors, pumps, HVAC equipment, air compressors, etc. , by sensing phase loss, low voltage or phase reversal.
With correct power applied, the DPDT output contacts transfer, and drop out when a fault condition or loss of power occurs. An adjustable trip delay prevents nuisance tripping. The restart delay timer prevents short cycling, which is primarily used with HVAC and compressor motors.
The DPDT output contacts allow the Model 2652 to be used in control circuits and alarm circuits. The automatic reset version can be converted to a manual reset, by adding a normally closed switch. The different voltage versions of the Model 2652 can be adjusted over a wide operating range. This unit is housed in an ABS plastic surface-mount case to reduce space requirements.

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.
