Versions Available - ABB V-Contact VSC Series Installation And Service Instructions Manual

The energy needed for operation is not sup-
plied directly by the auxiliary power supply, but
is always "stored" in the capacitor which acts
as an energy accumulator, and therefore op-
eration always takes place with constant speeds
and times, regardless of the divergence of the
power supply voltage from the rated value.
The auxiliary power supply only has the aim of
keeping the capacitor charged. Consumption
is therefore minimal. The power required is less
than 5 W. In order to re-instate the rated en-
ergy value in the capacitor following an opera-
tion, there is an inrush of 15 W for a duration of
a few tens of milliseconds.
Careful selection of the components and a pre-
cise design make the electronic multi-voltage

feeder extremely reliable, unaffected by elec-
tromagnetic interference generated by the sur-
rounding environment and free of any emis-
sions which may affect other apparatus placed
in the vicinity.
These characteristics have made it possible for
the V-Contact VSC contactors to pass the elec-
tromagnetic compatibility tests (EMC) and ob-
tain the CE mark.
