About the MEAN WELL HDR-150-15

The MEAN WELL HDR-150-15 is a 150 W ultra-slim DIN-rail power supply that provides a stable 15 V DC / 9.5 A output in a compact 105 mm wide step-shape housing, ideal for space-constrained distribution boards and automation cabinets. Its wide 85–264 V AC / 120–370 V DC input range and high efficiency up to 89.5 % enable energy-efficient operation in building automation, household control systems, and industrial control environments. The adjustable 13.5–18 V output range allows fine tuning of the 15 V bus to compensate for voltage drops and to supply demanding loads such as relays, I/O modules, and logic controllers with sufficient headroom. The Class II plastic enclosure with reinforced insulation enhances electrical safety and simplifies installation by removing the need for a protective earth connection. Combined with fanless convection cooling, 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-150-15 is a robust, long-life 15 V power solution for modern building and industrial automation systems.
