Three-phase monitoring relay with NFC configuration

29 September 2017

Available from Carlo Gavazzi UK, DPD is an NFC configurable three phase or three phase + neutral multifunction monitoring relay suitable for both Delta and Star mains.

This 3-phase voltage and frequency monitoring relay provides a high degree of flexibility in very compact dimensions, offering a wide range of features in a product just 22.5mm wide, with voltage measurements from 177 to 552V LL or 102 to 318V LN and an operating frequency from 45 to 440Hz. It protects loads from phase reversal, phase loss and phase asymmetry, voltage or frequency measurements outside the user-configured settings and/or thresholds.

The DPD relay is delivered with factory default alarm settings, which can be modified according to requirements. These settings can be altered using the App via a smartphone or desktop using a USB NFC reader/writer and uploaded to the DPD using NFC communication protocol. The app allows you to select the required settings, save them for future use, and send new configurations to the device. NFC communication allows the App to replicate easily the configuration from one device to another.

Only two part numbers cover all variants of mains type, voltage and frequency values reducing your stock inventory.  DPD has two separate relay outputs and up to 10 alarms combinable with AND / OR operators.

Three front LEDs provide visual indication of output status and alarm identification.

DPD is suitable for applications where it is necessary to monitor phase presence, correct phase sequence and the quality of three phase mains voltage + frequency: applications include pumps and compressors, power generating systems, lifts and escalators, HVAC, and materials handling. This new unit is also an excellent off the shelf solution for any electrical distributor, wholesaler or panel builder.
