UMG 512
Current measurement
The UMG 512 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.

Please note!
The measurement lines must be suitable
for an operating temperature of at least
80°C!

The attached screw-type terminal must be
fixed using the two screws on the device!

Please note!
The UMG 512 is not suitable for measuring
DC voltages.

Attention!
The current transformer must have basic
insulation per IEC 61010 1:2010, as a
minimum, for the nominal voltage of the
circuit to be measured.
