Product description
Intended use
The UMG505 is designed for fix mounting in low and
medium voltage switchgear and for measurement of
voltage, current, power, energy and harmonics etc.
Real and reactive energy can be given out via pulse
signal at the digital outputs. The results of the
measurement can be used for controlling
consumers in energy distributions or energy
generation.
The measurement with the UMG 505 can be carried
out in TN-, TC- and IT-networks. Alternating voltage
(50Hz/60Hz) up to 500VAC against ground and
870VAC outer conductor against outer conductor
can be connected directly to the voltage measuring
inputs. The voltage measuring inputs must be
connected via external fuses 2A (medium time lag)
to the UMG505. Voltage over 500VAC against
ground must be connected via voltage transformers.
The voltage measurement via voltage transformers
can be carried out with two or three voltage
transformers by choice.
To the current measurement input, .../5A or .../1A
current transformers can be connected by choice.
In networks with voltage up to 150VAC against
ground, currents up to 5.2A can be connected
directly to the UMG 505 and be measured.
The connection of the auxiliary voltage, the measu-
rement inputs etc. are on the rear side via all-
insulated plug connectors. The auxiliary voltage
must be connected to the building installation via a
separation (switch or power switch) and a 2...10 A
overload protection.
A protective wire connection is necessary for
operation of the UMG 505.
Attention!
Measurement in systems with pulse load is
not possible, because no continuous scan-
ning of the measuring signals is carried out.
