Description

The Digitus DN-PWR-SST-1512 is an especially compact 12 V rail power supply with 15 W power. With a width of just 18 mm, it is ideal for installations where every millimeter counts - for example in wiring closets, automation or IoT switching cabinets. The broad input voltage range of 90–264 V AC / 127–370 V DC makes a universal application possible. At the output the power supply 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 Insulation Class II, Class 2/LPS and tested EMC-conformity the DN-PWR-SST-1512 fulfills high demands in the control cabinet and building installation sector. It is suitable Ideal for applications in building automation, for example for the supply of 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 logic. In industrial and automation technology it supplies PLC sub-modules, I/O modules, RS485/RS232 communication devices, mini-PLCs or relay field modules. Also excellent for IoT and Edge applications such as gateways, protocol converters, edge sensors, low Power WLAN or mobile modules and microcontroller applications. In safety and access control technology, it serves as a stable supply for door opener modules, card and RFID readers as well as intercom and intercom systems.
