Power supply units are part of the S5-135U/155U central controllers
and of the EU 183 and EU 185 expansion units.
The following section provides an overview of power supply types,
their functions, indicators and controls and their inputs and outputs.
Your CC/EU contains one of the following power supply units (PSUs):
Type of PSU Input
(Designation) Voltage
6ES5 955-3LC41 120 V AC
230 V AC
(selectable)
6ES5 955-3LF41 120 V AC
230 V AC
(selectable)
6ES5 955-3NC41 24 V DC
6ES5 955-3NF41 24 V DC
The 5 V and 15 V output voltages are regulated; the 24 V output
voltage has coarse stabilization.
All four power supply units have safe electrical separation according
to VDE 0805/EN 60950.
Note
These power supply units are only intended for use with CCs/EUs.
