DPC01 and PPC01 are 3-phase mains monitoring relays.

They operate 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

• Wide voltages and frequency ranges. Working in systems from 100 to 690 VAC and 50 to 400Hz.

• 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.

• Two mounting versions. Available for DIN-rail (DPC01) and Plug-in (PPC01) mounting.

• 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.
