Description
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.
