Description

The DIGITUS DN-PWR-SST-1512 is a particularly compact 12 V DIN rail power supply with 15 W output. With a width of just 18 mm, it is ideal for installations where every millimeter counts - for example in distribution cabinets, automation or IoT control cabinets. The wide input voltage range of 90-264 V AC / 127-370 V DC enables universal use. At the output, the power supply unit provides a stable 12 V DC voltage with 1.25 A, ideal for control systems, sensors, modules and numerous electronic systems. The output voltage can also be finely adjusted between 10.8 and 13.8 V. Thanks to integrated short-circuit, overload and overvoltage protection, the power supply works safely and reliably even in demanding environments. With Class II insulation, Class 2/LPS and tested EMC conformity, the DN-PWR-SST-1512 meets high requirements in control cabinets and building installations. It is ideal for applications in building automation, for example for supplying 12 V sensors and actuators, control modules such as relay cards or low-power actuators as well as door intercoms, switching modules and smart home logics. In industrial and automation technology, it supplies PLC sub-assemblies, I/O modules, RS485/RS232 communication devices, mini PLCs or relay field modules. It is also ideal for use in the IoT and edge sector - e.g. for gateways, protocol converters, edge sensors, low-power WLAN or mobile radio modules and microcontroller applications. In security and access technology, it serves as a stable power supply for door opener modules, card and RFID readers as well as intercom and intercom systems.
