Description
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 tolerance.
Power supply provided by the monitored mains.
Two independent delay functions, up to 30 s, 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 400 Hz.
• 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.
Main 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, undervoltage, asymmetry and tolerance setpoints.
• Time delay.
• Two changeover relay outputs.
