Overview
Function
3UG46 33 monitoring relays
The 3UG46 33 voltage monitoring relay has an internal power
supply and performs overshoot, undershoot or window monitor-
ing of the voltage depending on how it is parameterized.
The device is equipped with a display and is parameterized
using three buttons.
The operating and measuring range extends from 17 V to
275 V AC/DC. The threshold values for overshoot or undershoot
can be freely configured within this range. If one of these thresh-
old values is reached, the output relay responds according to
the set principle of operation as soon as the tripping delay time
has elapsed. This delay time U
the ON-delay time on
The hysteresis is adjustable from 0.1 to 150 V. The device can be
operated on the basis of either the open-circuit or closed-circuit
principle and with manual or auto RESET. One output
changeover contact is available as signaling contact.

The relays monitor single-phase AC and DC voltages against the
set threshold value for overshoot and undershoot. The products
differ with regard to their power supply (internal or external).
