Features:
- Accepts a wide 16.8 to 138 V DC operating input range.
- Delivers regulated 24 V DC at a 2 A rated load.
- Restarts automatically after an electronically protected output short circuit is cleared.
The ordered module is the DC-input PS 305 execution with 48 W rated output capacity.
It establishes a local 24 V supply for S7-300 and ET 200M electronics in DC-fed cabinets.
Input polarity, earthing, branch protection and total downstream current must be resolved before wiring.

- Battery-backed automation panels can derive a regulated 24 V control rail from the wider station DC bus.
- Remote I/O cabinets use the supply where AC mains are unavailable but S7-300-compatible loads remain required.
- Process skids with 48 V or 110 V DC distribution can feed lower-voltage controller and sensor circuits.
- Electronic output protection limits fault current during a 24 V short circuit.
- Automatic restart restores the output after the external fault has been removed.
- IP20 construction requires installation inside a suitable control enclosure.
- The rated output is 48 W at 24 V DC and 2 A continuous current.
- Published efficiency is approximately 75% under the specified operating conditions.
- Cabinet heat calculations must include conversion losses at the expected load.
- The documented operating range extends from -25 to 70 °C with applicable loading conditions.
- Ventilation clearances should prevent neighbouring equipment from restricting natural cooling.
- Temperature assessment must use the actual enclosure ambient rather than room temperature alone.
