Note
Due to the output current of the 3SK1230 power supply (= 0.6 A), the use of 3SK1 basic units
with semiconductor outputs is only possible to a limited extent. The output current of all
semiconductor outputs can be up to 0.4 A here (depending on the system conguration).
5.5.2.2 Applications
The 3SK1230 power supply generates a stabilized output voltage of 24 V DC from 110 ... 240 V
AC/DC. The 3SK1230 power supply can supply the 3SK1 Advanced device series with 24 V DC via
3ZY12 device connectors or via the +/– output terminals.
The "INS" START pushbutton input of the 3SK1 device series must be supplied from the 3SK1230
power supply.
NOTICE
Two power supplies in parallel are not permissible! Only one 3SK1230 power supply is
permitted in each system conguration.
