The MeanWell HDR-30-12 is a 30W ultra-slim DIN rail power supply designed to be mounted on TS-35/7.5 or TS-35/15 rails, with a width of only 35mm (2SU), optimizing space inside electrical cabinets. It supports an AC input from 85VAC to 264VAC (up to 277VAC operational) and complies with European standards for harmonic currents (BS EN/EN61000-3-2). Its plastic housing provides effective protection against electrical hazards. With an efficiency of up to 87%, the HDR-30 operates in an ambient temperature range of -30℃ to 70℃, thanks to natural air convection. Additionally, it offers complete protection against short circuits, overvoltage, and overloads, and is certified for use in home automation and industrial control (IEC62368-1, UL508, UL62368-1, BS EN/EN61558-2-16), making it an ideal solution for both residential and industrial applications.
