3UG4983-.A voltage reducer module for extending the voltage range
The 3UG4983-.A voltage reducer module can be used to extend the measuring range of the
rated line voltage U
n
to be monitored. The voltage reducer module is used to connect the
3UG4583 insulation monitoring relay to systems with up to 690 V AC and 1000 V DC. The voltage
reducer module is connected to terminals VS, V1+ and V1- of the insulation monitoring relay.
These accessories are described in Chapter "3UG4983 voltage reducer module for the
3UG4583-1CW30 monitoring relay (Page 267)".
