Description
DPB51 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.
Power supply provided by the monitored mains.
Delay on alarm, up to 30s, for over/under voltage alarms.
For mounting on DIN-rail or back panel.
Benefits
• Wide voltages ranges. Working in systems from 208 to 480 VAC.
• Adjustable voltage levels and time delay. To allow a correct response to real alarm conditions.
• Output and status LED indication. For quick troubleshooting.
• Ultra-high harmonic immunity. For very noisy environments.
• High Compactness. 17.5 mm DIN rail housing.
Features
• Monitoring 3-phase mains with 3 wires (3P) or 4 wires (3P+N).
• Detection of the correct phase sequence and phase loss.
• Front dial adjustable overvoltage and undevoltage setpoints.
• Time delay.
• Changeover relay output
