About the MEAN WELL HDR-100-24N
The MEAN WELL HDR-100-24N is the Non‑LPS version of the HDR‑100‑24 models and delivers up to 100.8 W at 24 V DC and 4.2 A in an ultra‑slim 70 mm DIN‑rail housing. Its extended 21.6–29 V adjustment range offers additional voltage headroom for long cable runs, inductive loads and demanding 24 V control circuits, going well beyond the tighter LPS‑compliant window of “blank” units. Combined with universal input, high efficiency, fanless free air convection, comprehensive protection features and broad safety/EMC approvals, HDR-100-24N is a powerful, flexible 24 V supply for industrial control systems, building automation, valves, relays, sensors and OEM applications that must fully utilize the 100 W class.
