The DIGITUS DN-PWR-SST-2412 is a powerful 12 V DIN rail power supply with 24 W rated power and a compact step-shape design. With a width of just 35 mm, it is ideal for distribution boards, control cabinets, automation modules and IoT infrastructures where every millimeter counts. The wide input voltage range of 90-264 V AC / 127-370 V DC enables worldwide use, while the output provides a stable 12 V DC voltage with 2 A. The output voltage can be flexibly adjusted between 10.8 and 13.8 V - a decisive advantage for long cable runs or consumer loads that require precise voltage adjustment. Thanks to comprehensive protective circuits such as short-circuit, overload and overvoltage protection, the power supply works reliably even under demanding conditions. The combination of Class II, Class 2/LPS insulation, high efficiency of 88%, wide temperature range and robust EMC design makes the DN-PWR-SST-2412 the ideal voltage source for modern automation, building and IoT systems. Typical applications include 12 V sensors and actuators, control modules such as relay cards or zone controllers, door intercoms, switching modules and smart building logic. In industrial and automation technology, the stable 12 V supply enables the reliable operation of PLC slave units, I/O modules, RS485/RS232 communication devices, mini PLCs or relay field modules. The power supply unit also reliably supplies gateways, protocol converters, edge sensors, embedded modules and communication components in the IoT and edge computing sector. In security and access control, it supplies stable power for door opener modules, card and RFID readers, video door stations as well as intercom and access communication systems.
