Attention!
Current transformers can lead voltage, which
is dangerous to touch and should be earthed.
Current transformers, not loaded at the
secondary, can lead voltage dangerous to
touch and should be short circuited.
Measuring current
The UMG505 is designed for the connection of
current transformes with secondary currents of ../1A
and ../5A. When the device is delivered, a current
transformer of ../5A is set.
Each currrent measurement input can be loaded
with 5,2A over a long period or for 2 seconds with
180A.
Via the current measurement inputs only alternating
current can be measured but no direct current..
