## **DPD02** 

## **NFC-Configurable 3-Phase voltage and frequency monitoring relay** 

## **Benefits** 

- **Wide voltage range** . Working in systems from 208 to 480 VAC. 

- **NFC Communication** . Through the NFC communication, via smartphone, tablet or PC, DPD02 can be configured and provide real time operation data such as: alarms status, voltage and frequency readings. 

- **Output and status LED indication** . For quick troubleshooting. 

- **Adjustable power ON delay** . To avoid nuisance tripping at start-up. 

- **Ultra-high harmonic immunity** . For very noisy environments. 

## **Description** 

DPD02 is a multifunction 3-phase mains monitoring relay. 

It operates on 3P and 3P+N systems, monitoring phase loss and phase sequence, overvoltage and undervoltage, over and under frequency and voltage asymmetry. 

Power supply provided by the monitored mains. 

Several alarm and delay functions can be configured in the unit to provide specific monitoring on voltage and frequency. 

Through the DPD APP the user can configure the unit at any time or check the device operation status. 

## **Applications** 

DPD02 is particularly suited for generators, either fuel powered or renewable energy ones and on Combined Heat and Power systems. It is also used to monitor loads sensitive to voltage and frequency fluctuations. 

## **Main features** 

- Monitoring 3-phase mains with 3 wires (3P) or 4 wires (3P+N). 

- Detection of the correct phase sequence, phase loss, correct voltage, frequency and asymmetry. 

- Time delay. 

- Two changeover relay outputs. 

- NFC interface.

## **Operating description** 

## **Device configuration** 

The relay is fully configurable via the smartphone or PC DPD APP. 

DPD02 is equipped with built-in NFC communication. 

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. 

DPD02 can be configured without taking it out of the box. 

The configuration can be prepared on the PC or smartphone, downloaded from another device, by means of NFC, or loaded from a file. 

Once a configuration has been prepared on the PC it can be uploaded to one or more DPD02. 

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 DPD02 in order to avoid tampering or unauthorized configuration. The locking/ unlocking procedure is managed through one of the available apps.

Asymmetry is an indicator of the mains quality and it is defined as the absolute value of the maximum deviation among the mains voltages, divided by the nominal voltage of the 3-phase system. The definition changes according to the voltage reference: 

|**Main type**|**Voltage asymmetry (%)**|
|---|---|
|3P|max [AVpn-pnl x 100<br>Vanom|
|3P+N|max |AVpr-n| x 100<br>Vanom|

_Phase-neutral monitoring_ 

**Alarms** 

There are 2 types of alarm: 

||**Priority**|**Non priority**|
|---|---|---|
|**Description**|Priority alarms trip both outputs at the same time<br>when they are triggered|Non priority alarms are totally configurable by the<br>user. Type of measurement to be monitored and<br>trigger value can be freely set, within the specified<br>ranges, and changed at any time:|
|**Type**|Phase loss<br>Neutral loss (in "Star" configured systems)<br>Incorrect phase sequence<br>Out of range measurement|Undervoltage U<<br>Overvoltage U><br>Overfrequency f><br>Underfrequency f<<br>Asymmetry|
|**Configuration**|Each one of the priority alarm can be disabled indi-<br>vidually.<br>The setpoint can be adjusted for the phase or neutral<br>loss.|Up to 10 alarms among the above types can be<br>configured. As there are 2 outputs on DPD02,<br>some alarms can be configured without being dir-<br>ectly associated to an output.<br>Logical functions like AND and OR can be used to<br>connect several alarms to the same relay output.|
