About the MEAN WELL HDR-150-48
The MEAN WELL HDR-150-48 is a 150 W ultra-slim DIN-rail power supply that delivers a regulated 48 V DC / 3.2 A output in a compact 105 mm wide step-shape housing, ideal for narrow distribution boards and space-limited control panels. With its wide universal input range of 85–264 V AC or 120–370 V DC and high efficiency up to 90.5 %, it is well suited for energy-efficient 48 V bus systems in building automation, industrial control, and communication equipment. The adjustable 43.2–55.2 V output range provides flexibility to compensate for voltage drops and to feed downstream DC/DC converters, actuators, and communication modules with stable 48 V power. Its Class II plastic enclosure with reinforced insulation enhances electrical safety and simplifies installation by eliminating the need for a protective earth connection. Combined with fanless convection cooling, very low no-load power consumption below 0.3 W, a wide operating temperature range from −30 °C to +70 °C, and comprehensive protection and certification features, the HDR-150-48 offers a robust, long-life 48 V power solution for demanding building and industrial automation applications.
