C269R
Categories: 3-Phase-Monitors, 269R-SeriesThe Model 269R Over & Under 3-Phase Monitor continuously monitors 3-phase lines for high voltage, low voltage, phase loss or phase reversal, and an adjustable . 3 – 5 minute restart delay. This device features a solid-state voltage and phase angle sensing circuit, which drives a SPDT output relay.
The Model 269R is independent of the system load, and may be used on any horsepower motor. When phase sequence is correct, and the voltage remains between the upper and lower trip points, the output relay remains energized. When a fault condition is sensed, the output relay drops out.
The Model 269R does not require a neutral connection, and can be used on Wye or Delta systems. Each of the four voltage versions can be adjusted over a wide range. An adjustable restart delay (0.3-5 minutes) allows compressor head pressures to bleed off, in the event of short-term power failures. OVER and UNDER voltage failure indicators aid in cali bration and system troubleshooting.

3-Phase Monitor with Trip and Restart DelaysSelect optionsThe Model 18 continuously monitors 3-phase power lines for abnormal conditions. When properly adjusted, the Model 18 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 18 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 18 is UL Recognized in the U.S. and Canada and is available with optional gold flashed silver contacts for low current applications.
