Carlo Gavazzi Monitoring Relay, TRMS 3-Ph & 3-Ph+N, Phase Loss/Phase Sequence/Over & Under voltage/Over & Under Frequency, 2x SPDT, Din-Rail, Supply: 600-690VAC.
DPC02 is a multifunction 3-phase mains monitoring relay. It operates on 3P and 3P+N systems, monitoring phase loss and phase sequence, overvoltage and undervoltage, over and under frequency. Power supply provided by the monitored mains. Two independent delay functions, up to 30s, for over/under voltage and frequency alarms.
Applications
DPC02 are particularly suited for generators, either fuel powered or renewable energy ones and on Combined Heat and Power systems. It is also indicated to monitor loads sensitive to voltage and frequency fluctuations.
General Characteristics
Monitoring 3-phase mains with 3 wires (3P) or 4 wires (3P+N).
Detection of the correct phase sequence, phase loss, correct voltage and frequency.
Front dial adjustable overvoltage, undervoltage and frequency setpoints.
Time delay.
Two changeover relay outputs.
Wide voltages ranges. Working in systems from 208 to 690 VAC.
Adjustable voltage levels, frequency and time delay, to allow a correct response to real alarm conditions.
Output and status LED indication, for quick troubleshooting.
Adjustable power ON delay. To avoid nuisance tripping at start-up.
Ultra-high harmonic immunity. For very noisy environments.
