10.3.2 Functions
General functionality
Depending on the setting, the 3UG4633 voltage monitoring relays are self-powered
(measuring voltage = rated control supply voltage) and monitor an AC voltage or DC voltage at
terminals A1 and A2 of the device for overshoot (U▲) or undershoot (U▼) or in range
monitoring (U▲ and U▼).
The voltage monitoring relays are powered with a rated control supply voltage of 17 to 275 V AC/
DC through terminals A1/A2.
