DPC01DM1K 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, voltage asymmetry and torelance. Power supply provided by the monitored mains.

Two independent delay functions, up to 30s, for over/under voltage and asymmetry/tolerance alarms.

Benefits

• Very high voltage values. Working in 750 and 1000 VAC systems.

• Adjustable voltage levels, asymmetry, tolerance 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.

Features

• Monitoring 3-phase mains with 3 wires (3P) or 4 wires (3P+N).

• Detection of the correct phase sequence, phase loss, asymmetry and tolerance.

• Front dial adjustable overvoltage, undevoltage, asymmetry and tolerance setpoints.

• Time delay.

• Two changeover relay outputs.
