About the MEAN WELL HDR-100-48
The MEAN WELL HDR-100-48 is an ultra‑slim 100 W class DIN‑rail power supply that delivers a regulated 48 V DC output at up to 1.92 A in a compact 70 mm (4 SU) housing, ideal for 48 V system buses in space‑constrained control panels. Its universal input range, high efficiency, very low no‑load power consumption and fanless free air convection make it a highly energy‑efficient 48 V source for telecom, industrial control and building automation applications. LPS‑compliant “blank” models with a tighter adjustment window and higher‑power “N” versions with an extended adjustment range up to 55.2 V allow designers to balance safety classification against additional voltage headroom. Combined with a Class II plastic enclosure, comprehensive protection features and broad international approvals, HDR-100-48 provides a robust, low‑maintenance 48 V power solution for controllers, actuators and communication equipment.
