These slim DIN-rail power supplies offer an efficient and reliable power solution for industrial applications. With a width of less than 4 cm and a high efficiency rating of 90.5%, they are ideal for powering Ethernet switches, media converters, and other devices. Thanks to the universal input voltage (85 to 264 VAC) and robust design, the power supplies operate in a wide temperature range from -25 to +70 °C. Additionally, the units are protected against short circuits, overloads, and overvoltage, and are certified by cUL and CE.

The LED indicator displays the DC power status, and the touch-safe terminals provide extra safety. The compact design and extended temperature range make these power supplies suitable for confined spaces and demanding environments.
