DPB51CM44

DPB51CM44 is a true RMS 3-phase voltage monitoring relay. It operates on 3P and 3P+N systems, monitoring phase loss and phase sequence, overvoltage and undervoltage. The power supply is provided by the monitored mains. Delay on alarm, upto 30s, for over/under voltage alarms. It has output and status LED indications for quick troubleshooting and ultra-high harmonic immunity for very noisy environments.
