Description

The DIGITUS DN-PWR-SST-1524 is a compact 24 V DIN rail power supply with 15 W output power in an extremely slim design. With a width of just 18 mm, it is ideal for installations with limited space - for example in automation and building installations, IoT control cabinets or in security technology. The wide input voltage range of 90-264 V AC / 127-370 V DC enables flexible and worldwide use. The power supply unit provides a stable 24 V DC output voltage of 0.63 A, which can be finely adjusted in the range from 21.6 to 29 V - a great advantage for long cable runs or sensitive loads. Thanks to the integrated short-circuit, overload and overvoltage protection, the power supply works particularly reliably and effectively protects connected devices. With Class II insulation, Class 2/LPS and tested EMC conformity, it meets the requirements of modern industrial and building technology applications. The high efficiency, robust temperature behavior, compact design and worldwide application range make the DN-PWR-SST-1524 the ideal power supply for building automation, industrial electronics, IoT and edge technology, PLC environments as well as security and access control. Typical applications include 24 V sensors and actuators, control and relay modules, room or zone controllers, door intercoms, switching modules and smart building logic. In industrial and automation technology, it supplies PLC sub-assemblies, 24 V I/O modules, RS485/RS232 communication devices, mini PLCs or relay panels. In IoT and edge scenarios, it supplies gateways, industrial IoT modules, protocol converters, embedded systems and communication components. In security and access technology, it supplies power for door openers, card and RFID readers, video door stations as well as intercom and access communication systems.
