Auxiliary power requirements

Air-cooled S120 Cabinet Modules require an auxiliary power supply (line voltage 1AC, 230 V 1AC, 24 V DC) in order
to operate correctly. The power requirement on every voltage level must be taken into account at the configuring
stage and supplied from external sources. Fuse protection for the auxiliary energy must also be provided externally.
When selecting the external 24 V supply, it must be noted that the
capacitors in the electronics power supplies of all connected Cabinet
Modules must be charged when the power supply is switched on. The
24 V supply must therefore initially supply a peak current to charge these
capacitors. This peak current might correspond to a multiple of the
current I which is calculated from the sum of the values for all
DC ext
connected Cabinet Modules as given in the tables on the following
pages. Account must be taken of this peak current when protective
devices such as miniature circuit breakers are installed. The peak current
flows for a period t lasting only a few 100 ms. The peak value is
e
determined by the impedance of the external 24 V supply or its
electronically limited maximum current.
