Carlo Gavazzi DPB02 Monitoring Relay

The Carlo Gavazzi DPB02 monitoring relay is a three-phase monitoring relay used for phase sequence, phase loss and asymmetry with built-in time delay function. The DPB02 features a switch mode power supply, which provides a wider input voltage range to cover different mains voltages, while reducing heat dissipation and improving reliability and stability. The monitoring range of 380 to 480 VAC is covered by two multi-voltage relays. Connected with the three phases (and neutral), the DPB02 operates when all three phases are present at the same time, the phase sequence is correct and the asymmetry is under the set level. The unit can be customized to each user application by adjustments to over and under voltage, alarm delays, and asymmetry.
