DIGITUS Step-Shape DIN-Rail Power Supply 12V DC 2A 24W · Slim 35 mm, Class II · AC/DC Input

The DIGITUS DN-PWR-SST-2412 is a compact 24 W DIN-rail power supply that delivers a regulated 12 V DC at up to 2 A from a single 35 mm-wide module on a TH35 rail. Its step-shaped housing is the profile used in modern distribution boards, so it sits flush behind a standard cover plate next to breakers and modular devices. DIGITUS designs it for sensors, IoT gateways and low-voltage electronics in automation, building-automation and security installations.

Input is wide-range: 90–264 V AC or 127–370 V DC, so the same module works on 230 V mains and on a DC bus. The output is trimmable from 10.8–13.8 V, regulated to ±2%, and protected against short circuit and overload with automatic recovery, plus an overvoltage limit of 15–18 V. The double-insulated Class II design needs no protective earth, and the unit is certified to UL 62368-1 and EN 62368-1 with EN 55032 Class B emissions.

• 1 × DIGITUS Step-Shape DIN-rail power supply 12 V / 24 W (DN-PWR-SST-2412)
• 1 × Quick Installation Guide
• No DIN rail, wiring or end clamps included

• Load budget: 2 A at 12 V (24 W). Add up the maximum current of your sensors or controller and keep about 20% in reserve.
• Width on the rail is only 35 mm (2 modules), height 90 mm and depth 58 mm — it fits shallow distribution boards with a standard step profile.
• Terminal order is printed on the unit: AC/L (1), AC/N (2), +V (3), -V (4). Wiring must be done by a qualified electrician with the supply isolated.
• Overload is handled in hiccup mode: the output switches off and retries automatically once the fault is gone — no manual reset needed.

• It will not power loads above 2 A / 24 W — use a larger unit for motors, PoE switches or heaters.
• It is not for outdoor or wet locations without a suitable enclosure; DIGITUS specifies indoor use.
• It is not a plug-in adapter: no mains plug, no barrel jack and no USB output.
• No status relay, battery backup or redundancy function is published.
