Mode of Operation
A 82-10 and A 82-20 are
true RMS current metering
transformers with standard
source/sink output 0-20 mA /
4-20 mA, whereas A 82-30
is a metering tranformer with
0-10 VDC output voltage.
This makes them very useful
as an AC current interface to

EMC
The metered conductor is
drawn through the central
hole of the current metering
transformer. It is possible to
meter currents below the
nominal range by drawing
the conductor through the
hole several times. If the
