Carlo Gavazzi Three-phase monitoring relay

The DPD series three-phase voltage and frequencing monitoring relay with NFC configuration provides protection against phase reversal and phase loss and when phase asymmetry, voltage or frequency measurements are not within the user-configured settings or thresholds. The settings can be modified through an Android app via smartphone or tablet or via a USB NFC reader/writer connected to a computer. Under- and over-threshold settings can be set, as well as hysteresis and time delays. They are uploaded into the series by means of its NFC configuration. Neither potentiometer settings nor DIP switches are used for the device setup.
