UMG 104
Product Description
Intended use
The UMG104 is intended to be used for the
measurement and calculation of electrical
variables such as voltage, current, energy,
work, harmonic components, etc. in building
installations, at distribution boards, circuit-
breakers and busbar trunking systems.
Measuring-circuit voltages and currents must
originate from the same system.
The UMG104 is permanently installed in
control cabinets or small distribution boards.
It can be installed in any position.
The measurement results can be displayed,
stored and read out via serial interfaces and
further processed.
The voltage measurement inputs are designed
for measurements in low-voltage systems in
which rated voltages up to 300 V conductor
to earth and surge voltages of overvoltage
category III can occur.
The current measurement inputs of the
UMG104 are connected via external ../1A or
../5A current transformers.
Mains failure detection
The mains failure detection takes place via the
voltage measurement inputs. The selection of
voltage measurement inputs can be configured
using the GridVis software.
Mains failure stored energy time
The UMG104 bridges the following mains
failures at the auxiliary voltage input:
Mains voltage Stored energy time
230V AC max 80ms
Measurement in medium and high-voltage
systems takes place with current and voltage
transformers. Special safety requirements
must be complied, which are not dealt with in
any greater detail here.
The UMG104 fulfils the test requirements for
use in industrial areas.
