5.4.2 Power supply 3SK1230
5.4.2.1 Device features
MLFB:
3SK1230-xAW20 110 ... 240 V AC/DC
(x) 1 = screw-type terminal; 2 = push-in terminal
Device properties:
● Wide-range input: 110 ... 240 V AC/DC
● Rated output voltage: 24 V DC
● Rated output current: 0.6 A
● 1 LED for status display
● Connection interface
● Enclosure width 22.5 mm
● Removable terminals
Note
Due to the output current of the power supply 3SK1230 (= 0.6 A), the use of 3SK1 basic
units with solid-state 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 configuration).
5.4.2.2 Applications
The power supply 3SK1230 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 3ZY device connectors or via the +/– output terminals.
The START pushbutton input "INS" 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 is permitted per
system configuration.
