DUB01 TRUE RMS OVER/UNDER VOLTAGE RELAY
Category: Phase/Voltage Current Monitoring
DUB01 and PUB01 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. 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.
