Carlo Gavazzi DPD three-phase monitoring relay

May 23, 2017 – Carlo Gavazzi has announced its DPD series three-phase monitoring relay with NFC configuration, describing it as providing the “utmost flexibility in very compact dimensions.”

According to Carlo Gavazzi, it provides protection against phase reversal, phase loss and if the phase asymmetry, voltage or frequency measurements are not within the user-configured settings and/or thresholds. The DPD series settings can be modified through an Android App via a smartphone or tablet or via a USB NFC Reader/Writer (part number ACR1252U) connected to a computer. Under and over threshold settings can be set, as well as hysteresis and time delays. They are uploaded into the DPD Series by means of its NFC configuration. Neither potentiometer settings nor DIP switches are used for the device set-up, and after it is set-up, it can be password protected, to increase safety measures while in use.
