Compact DIN rail supply for control panels

The SIEMENS SITOP PSU100C delivers a regulated 12 V DC output at 24 W from a 100 to 230 V AC or 110 to 300 V DC input. It fits on a standard DIN rail inside enclosures rated to NEMA 1 and IP20, serving automation and building-system loads that require a stable low-voltage rail.

Convection cooled with green LED status

Natural convection handles the 24 W load without a fan, so acoustic noise is absent in normal operation. The unit tolerates an ambient range of -20 to 70 °C and maintains output with a hold-up time greater than 20 ms; ripple and noise measure 200 mV peak-to-peak and 40 mV RMS. Peak current capability reaches 33 A for brief inrush events.

Plastic housing and single-phase wiring simplify

The 30 mm wide plastic case leaves dense rail space for adjacent modules. A green OK LED gives immediate visual confirmation of output presence. Single-phase 50 to 60 Hz supply wiring keeps termination straightforward for panel builders.

Questions about this item

How do I mount the 30 mm wide DIN-rail unit and what step is often missed?

Clip the plastic case onto a standard DIN rail, then verify the green LED OK signal lights to confirm 12 V DC output is present.

Which part will need replacement first during continuous operation?

The internal electrolytic capacitors age fastest; plan replacement after several years at the upper end of the -20 to 70 °C range.

What limit appears first when the supply runs at 24 W continuously?

Output ripple reaches the specified 200 mV peak-to-peak before thermal protection engages at 70 °C.
