The Carlo Gavazzi DUB02 / PUB02 Monitoring Relay is a precise, one-phase, TRMS AC overvoltage or undervoltage relay. The DUB02 / PUB02 monitors its own power supply, selectable by DIP-switch. The latch function allows the relay to remain energized even after the end of the alarm condition. The inhibit function can be used to avoid relay operation when conducting maintenance or swapping out hardware.
