Power adapter/inverter MEAN WELL HDR-100-48, 100 W, 48 V output, 85–264 V input, RoHS, 70×54.5×90 mm

MEAN WELL HDR-100-48 is an ultra-slim DIN-rail power adapter/inverter designed to provide a stable 48 V DC output at up to 100 W. The unit accepts a wide AC input range of 85–264 V and features a compact metal housing measuring 70 × 54.5 × 90 mm, making it suitable for confined electrical cabinets and industrial racks. The supply meets RoHS requirements and implements safety features consistent with limited power source (LPS) classification.

Advantages

The HDR-100-48 delivers reliable 48 V output with up to 1.92 A continuous current while occupying minimal DIN-rail space thanks to its ultra-slim profile. Wide input voltage compatibility allows use on international mains without additional converters. A robust metal enclosure offers improved heat dissipation and mechanical protection for industrial environments. RoHS compliance ensures reduced hazardous substances in the product construction.

How to use

Install the HDR-100-48 on a standard DIN-rail inside an electrical cabinet in accordance with applicable wiring standards. Connect the AC mains input within the specified 85–264 V range and ensure correct polarity on the 48 V DC output terminals before powering connected equipment. Allow adequate ventilation around the unit and avoid mounting directly next to heat sources. Verify grounding and protective devices are present as required by local regulations.

Recommendations

For stable performance, place the adapter in an environment within the manufacturer's recommended ambient temperature and avoid enclosure overcrowding. Use proper surge protection on the AC input for installations in areas prone to voltage spikes. When deploying multiple units, consider rack layout to maintain airflow and service access.
