Carlo Gavazzi Monitoring Relay Voltage 3-Phase Din-Rail DPB02CM44

Carlo Gavazzi Monitoring Relay True RMS 3-Phase (3P & 3P+N), Phase Loss/Phase Sequence/Voltage Asymmetry, DIN-Rail, SPDT, Supply: 208-480VAC, 50-400Hz.

DPB02 and PPB02 are 3-phase mains monitoring relays. They operate on 3P and 3P+N systems, monitoring phase loss, phase sequence and voltage asymmetry. Power supply provided by the monitored mains. Delay on alarm, up to 30s, for asymmetry alarm.

General Characteristics 

• Solutions for a wide range of applications: lifts, escalators, HVAC, material handling, pumps, compressors and mobile machinery installation.
• Monitoring 3-phase mains with 3 wires (3P) or 4 wires (3P+N), detection of the correct phase sequence and phase loss.
• Wide voltages and frequency ranges, working in systems from 208 to 480 VAC and 50 t0 400Hz.
• Adjustable voltage asymmetry level and time delay, to allow a correct response to real alarm conditions and to avoid nuisanse tripping at start-up.
• Front dial adjustable voltage asymmetry setpoint.
• Output and status LED indication, for quick troubleshooting.
• Two mounting version, available for DIN-rail (DPB02) and Plug-in (PPB02) mounting.
• Ultra-high harmonic immunity, for very noisy environments.
• Changeover relay output.
