DETAILED DESCRIPTION

DPD02DM..

DPD is a threephase multifunction configurable monitoring relay suitable for both Delta and Star mains. It protects loads from wrong phase sequence, neutral and phase loss, additionally voltage, frequency and asymmetry thresholds can be set and provide output signals.
DPD has two separate relay outputs, so it is possible to provide 2 different signals for different purposes.
The DPD is delivered with factory default alarm values, if they are not completely suitable they can be modified according to own requirements.
3 front LEDs provide visual indication of outputs states and alarm discrimination.
Through the DPD APP the user can reprogram the unit at any time or check the device operation status.
NFC Communication. Through the NFC communication, via smartphone, tablet or PC, the DPD can be configured or provide real time operation data such as: alarms status, voltage & frequency readings.
With the DPD APP through the NFC communication it is possible to read or write the device configuration as well as reading the voltage, the frequency or the alarms in real time.
NFC communication does not require any power for the device configuration.
DPDs can be configured without taking them out of the box.
The configuration can be prepared on the PC or smartphone, downloaded from another device, by means of NFC, or picked from file.
Once a configuration has been prepared on the PC it can be uploaded to one of more DPDs.
NFC also allows, when necessary to download the configuration from a device, modify it if necessary and then upload it to another device.
It is possible to Lock the DPD in order to avoid tampering or unauthorized configuration. The locking/ unlocking procedure is managed through one of the available apps.
