About the MEAN WELL HDR-150-12

The MEAN WELL HDR-150-12 is a 150 W ultra slim DIN-rail power supply that delivers a robust 12 V DC / 11.3 A output in a compact 105 mm (6 SU) wide step-shape housing, ideal for space‑critical distribution boards and industrial control cabinets. Its wide 85–264 V AC / 120–370 V DC input range and high efficiency up to 89 % enable energy‑efficient operation in global household and industrial automation projects. The Class II plastic enclosure provides reinforced insulation and eliminates the need for a protective earth connection, significantly enhancing electrical safety for users and simplifying installation. With fanless free‑air convection cooling, low no‑load power consumption under 0.3 W, and an operating temperature range from −30 °C to +70 °C (with derating), the HDR-150-12 is designed for reliable, low‑maintenance 24/7 operation. The constant‑current overload characteristic and comprehensive international certifications make this power supply a strong choice for building automation, factory automation, control systems, and electro‑mechanical equipment that demand a stable and compact 12 V power rail.
