CMU Series Diversified Electronics atcdiversified.com 800.727.5646 246 Current Monitors // CMU Series The CMU Series is used to detect under current conditions. The internal relay is energized (Pick-up) when the monitored current is above the preset trip point. The relay de-energizes (Drop-out) when the current falls below the trip point for longer than the adjustable delay. The delay is incorporated to prevent nuisance tripping caused by momentary line dips. The relay re-energizes when the current rises 5% above the Dropout trip point for longer than 0.1 seconds. The relay has the automatic reset feature. An external CT may be used to extend the range of the Current Monitor.
