DUC01 1-Phase True RMS AC/DC Over & Under Voltage Monitoring Relay
DUC01 and PUC01 are precise TRMS AC/DC over+under, over+over or under+under voltage (selectable by DIP-switch) monitoring relays.
The voltage levels are adjustable separately and have their own time delay.
Owing to the built-in latch function, the ON-position of the relay output can be maintained. Inhibit function can be used to avoid relay operation when not desired (maintenance, transitions).
The LED's indicate the state of the alarm and the output relay.
