UMG 103
Fig.19.1 Example, current measurement
via additional ammeter.
Ammeter
If you not only want to measure the current
with the UMG103 but with an ammeter
also, the ammeter must be connected
in series to the UMG103.
Direct measurement
Nominal currents up to 5 A can also be
measured directly with the UMG103.
In this case it must be noted that each
current measurement input may be loaded
continuously with 6 A or for 1 second
with max 100 A.
As the UMG103 does not have any
integrated protection for the current
measurement, this protection (e.g. 6A
fuse type C) must be provided for during
installation.
