Voltage monitoring
3UG46 31/3UG46 32 monitoring relays
The 3UG46 31/3UG46 32 voltage monitoring relay is supplied
with an auxiliary voltage of 24 V AC/DC or 24 to 240 V AC/DC
and performs overshoot, undershoot or window monitoring of
the voltage depending on how it is parameterized. The device is
equipped with a display and is parameterized using three
buttons.
The measuring range extends from 0.1 V to 60 V or from
10 to 600 V AC/DC. The threshold values for overshoot or
undershoot can be freely configured within this range. If one of
these threshold values is reached, the output relay responds
according to the set principle of operation as soon as the delay
time has elapsed. This delay time U_Del can be set from 0.1 to
20 s.
The hysteresis is adjustable from 0.1 to 30 V or 0.1 to 300 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.
