About the MEAN WELL HDR-100-24
The MEAN WELL HDR-100-24 is an ultra‑slim 100 W class DIN‑rail power supply that provides a regulated 24 V DC output at up to 3.83 A in a compact 70 mm (4 SU) housing, ideal for space‑constrained 24 V control panels. With a universal input range, high efficiency up to 90 %, very low no‑load consumption and fanless free air convection, it delivers an energy‑efficient 24 V bus for building automation, household control systems and industrial control cabinets. LPS‑compliant “blank” models with a tighter adjustment window and higher‑power “N” versions with an extended adjustment range up to 29 V give designers flexibility between safety classification and additional voltage headroom. Together with the Class II plastic enclosure, comprehensive protection features and broad international approvals, HDR-100-24 is a robust, low‑maintenance 24 V power solution for PLCs, I/O modules, valves, relays and other 24 V control electronics.
