DUB03 1-Phase True RMS AC/DC Over or Under Voltage Monitoring Relay

DUB03 and PUB03 are precise TRMS AC/DC over or under voltage (selectable by DIP-switch) monitoring relays.

Owing to the built-in latch function, the ON-position of the relay output can be maintained.

The LED’s indicate the state of the alarm and the output relay
