UMG 509
Current measurement
The UMG 509 is intended for the connection of current
transformers with secondary currents of ../1A and ../5A.
The factory default for the current transformer ratio
is 5/5A and must be adapted to the current transformer
employed if necessary.
Only AC currents can be measured - DC currents cannot.
Any of the current measurement inputs can be loaded
with 120A for 1 second.
