The MEAN WELL HDR-100-12 is an ultra-slim 85.2 W DIN rail AC/DC power supply designed to provide reliable 12 V DC power for building automation, control panels and electrical equipment. As part of the MEAN WELL HDR-100 series, it combines a compact step-shaped enclosure with universal AC input capability, Class II isolation and comprehensive electrical protection.
This single-output switched-mode power supply delivers a regulated 12 V DC output at up to 7.1 A. The output voltage is adjustable, allowing the supply to be fine-tuned for compatible equipment. Its fanless design uses free-air convection cooling, while an integrated DC OK LED provides convenient visual indication that output power is available.
With a universal 85–264 V AC single-phase input and support for 120–370 V DC input, the HDR-100-12 provides flexible installation across a wide range of electrical systems. Its compact 70 mm-wide enclosure mounts directly onto TS-35/7.5 or TS-35/15 DIN rail, making it particularly suitable for building automation cabinets and space-conscious control panels.
DIN rail switched-mode power supplies convert incoming mains power into the stable DC voltage required by electronic control equipment. The MEAN WELL HDR-100-12 provides a regulated 12 V DC supply with up to 7.1 A of output current, making it suitable for powering a broad range of compatible building automation, control and electrical devices.
The HDR-100 series is designed around an ultra-slim step-shaped format for efficient installation inside distribution boards and control cabinets. Its universal input capability, Class II isolation, low no-load power consumption and fanless cooling make the HDR-100-12 a practical solution for modern building automation and electrical control systems.
