9.3

Series connection for increased voltage

To achieve an output voltage of 48 V DC, two 24 V SITOP power supplies of the same type

can be connected in series.
Depending on the grounding point of the secondary output voltages, voltages of +48 V,

±24 V or -48 V can be realized.

Note
For additional details, see Catalog KT 10.1 Chapter 15 Technical information and configuring

(see

)).

WARNING

SELV is not guaranteed in the case of a fault
When connecting two power supplies in series, the continuous, permissible SELV voltage

of a maximum of 60 VDC according to EN 60950-1 cannot be guaranteed in the case of a

fault.
