Description

The DIGITUS DN-PWR-SST-125 is an ultra-compact 5 V DIN rail power supply with 12 W output, specially designed for modern electrical and building installations. With a width of just 18 mm, it requires minimal space in distribution cabinets and is ideal for applications in which many low-voltage devices have to be operated in a very small space. Thanks to the wide input voltage range of 90-264 V AC / 127-370 V DC, the power supply unit can be used worldwide and provides a stable 5 V DC supply of up to 2.4 A. The output voltage can be set between 4.5 and 5.5 V, which enables perfect adaptation to microcontrollers, sensors or bus systems. The equipment includes comprehensive protective circuits such as short-circuit, overload and overvoltage protection. Class II, Class 2/LPS insulation and high efficiency ensure long-lasting, energy-optimized operation. With its robust temperature range of -20 to +47 °C, the DN-PWR-SST-125 is suitable for building automation, industry, smart home systems, access solutions, control systems, IoT gateways and wherever a reliable 5 V power supply is required. In industry, the power supply unit reliably supplies PLC sub-assemblies, I/O modules, RS485/RS232 communication devices, mini PLCs or relay field modules. It is also ideal in the IoT and edge environment - e.g. for gateways, protocol converters, edge sensors, low-power WLAN/mobile radio modules and microcontroller applications.
