Information about the MEAN WELL HDR-15-12
The MEAN WELL HDR‑15‑12 is a slim 15 W DIN rail power supply providing 12 V DC at up to 1.25 A, built in an ultra‑compact 17.5 mm (1 SU) plastic enclosure for space‑saving installations on TS35/7.5 or TS35/15 rails. Its wide 85–264 V AC input (with 277 V AC operational) and adjustable 12 V output range from 10.8 to 13.8 V make it suitable for a variety of 12 V control, sensor and logic applications in household and industrial environments.
Thanks to a typical efficiency of 85 % and fanless convection cooling, the HDR‑15‑12 operates from −30 °C to +70 °C when derating is applied, which is ideal for compact distribution boards and building automation panels. With constant‑current overload protection, overvoltage shutdown, low no‑load power consumption and a comprehensive set of safety and EMC certifications, it offers a cost‑effective and standards‑compliant 12 V DIN rail supply for household control systems, building automation and small industrial control systems.
