DPD Series three-phase monitoring relay with NFC Configuration provides the utmost flexibility in very compact dimensions and offers a wide range of features in a mere 22.5-mm product width.
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.
Settings can easily be modified through an Android App via a smartphone/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.
Main technical features include:
- 3-phase voltage and frequency monitoring relay
- Nominal measurement range from 177-552 v ac L-L and 102-318 v ac L-N
