Carlo Gavazzi Monitoring Relay NFC Frequency & Voltage 3-Phase Din-Rail DPD02DM44B

Carlo Gavazzi Monitoring Relay NFC-Configurable 3-Phase/3-Phase+N 240VAC, Multi-Function Frequency & Voltage, 2x SPDT, Din-Rail, Supply: 208-480VAC.

DPD02 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, over and under frequency and voltage asymmetry. Power supply provided by the monitored mains. Several alarm and delay functions can be configured in the unit to provide specific monitoring on voltage and frequency. Through the DPD APP the user can configure the unit at any time or check the device operation status.

Applications

DPD02 is particularly suited for generators, either fuel powered or renewable energy ones and on Combined Heat and Power systems. It is also used to monitor loads sensitive to voltage and frequency fluctuations.

General Characteristics

• Monitoring 3-phase mains with 3 wires (3P) or 4 wires (3P+N).
• Detection of the correct phase sequence, phase loss, correct voltage, frequency and asymmetry.
• Time delays.
• Two changeover relay outputs.
• NFC Interface.
• Wide voltage ranges. Working in systems from 208 to 480 VAC.
• NFC Communication. Through the NFC communication, via smartphone, tablet or PC, DPD02 can be configured and provide real time operation data such as: alarms status, voltage & frequency readings.
• 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.
