SITOP PSU400M
Description
The SITOP PSU400M is a power supply for connection to DC link voltages. It provides an output
voltage of 24 V to 28.8 V DC. The output voltage can be adjusted using an integrated
potentiometer.
The SITOP PSU400M is used to maintain the 24 V supply for S220 Smart Line Modules. When the
power fails, it automatically changes over to supply from the DC link. This makes it possible to
execute retraction movements in the event of a power failure.
