Power supply 3SK1230

5.4.2.1

Device features

Article number (MLFB):
3SK1230-xAW20
(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 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 configuration).
5.4.2.2

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 configuration.
