About the MEAN WELL HDR-15-48
The MEAN WELL HDR-15-48 is an ultra slim 15 W step‑shape DIN‑rail power supply that delivers a regulated 48 V DC output at 0,32 A in a compact 17,5 mm wide housing, ideal for narrow distribution boards and control panels. Its wide 85–264 V AC / 120–370 V DC input range and high efficiency up to 87 % make it a strong choice for global building automation and industrial control projects that require reliable 48 V bus power. The Class II plastic enclosure increases electrical safety by providing reinforced insulation and eliminating the need for a protective earth connection, which is particularly advantageous in household and retrofit installations. With low no‑load power consumption below 0,3 W, silent fanless convection cooling, and a broad operating temperature range from −30 °C to +70 °C (with derating), the HDR-15-48 supports energy‑efficient, maintenance‑free continuous operation. Its constant‑current overload behavior and comprehensive approvals for household and industrial control apparatus make this model a robust, easy‑to‑integrate 48 V supply for LED drivers, communication modules, control relays, and compact automation devices.
