Time Mark D2644 - 3-Phase Monitor, Auto Reset, 575 VAC, 450-575V, 60Hz, 7.5W

The Time Mark D2644 is a 3-phase monitor that continuously monitors 3-phase Wye or Delta systems for abnormal conditions. It offers 575 VAC of nominal AC voltage, 450-575V of adjustment range, 60Hz of frequency, and 7.5W of power consumption.

The solid-state electronic sensing circuitry drives an internal DPDT relay, allowing the Model 2644 to operate two motor control circuits, or a control circuit and an alarm circuit. An adjustable trip delay reduces or eliminates nuisance tripping caused by momentary voltage fluctuations on motor start-up. An optional restart-delay gives approximately a 3.5-minute delay when the relay drops out, to allow compressor head pressures to bleed off, in the event of short-term power failures.

The voltage adjustment range allows for proper calibration to existing conditions. Both TRIP and NORM indicators are provided to aid in adjustment and system troubleshooting. The D2644 model comes with an automatic reset. The Model D2644 Monitor is not sensitive to line current, and can be used with any size motor or compressor.
