DIGITUS Step-Shape DIN-Rail Power Supply 24V DC 0.63A 15W · Ultra-Slim 18 mm, Class II · AC/DC Input

The DIGITUS DN-PWR-SST-1524 is a compact 15 W DIN-rail power supply that delivers a regulated 24 V DC at up to 0.63 A from a single 18 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 21.6–29 V, regulated to ±2%, and protected against short circuit and overload with automatic recovery, plus an overvoltage limit of 30–36 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 24 V / 15 W (DN-PWR-SST-1524)
• 1 × Quick Installation Guide
• No DIN rail, wiring or end clamps included

• Load budget: 0.63 A at 24 V (15 W). Add up the maximum current of your sensors or controller and keep about 20% in reserve.
• Width on the rail is only 18 mm (1 module), height 90 mm and depth 58 mm — it fits shallow distribution boards with a standard step profile.
• Terminal order is printed on the unit: +V (1), -V (2), AC/N (3), AC/L (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 0.63 A / 15 W — use a larger unit for motors, PoE switches or heaters.
• It will not stay within rating in cabinets hotter than +47 °C ambient.
• 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.
