Bloc d'alimentation MEAN WELL UHP-1000-48

The MEAN WELL UHP-1000-48 is a slim AC-DC enclosed power supply with active PFC that delivers a single 48 V DC output at up to 21 A (1000 W). It accepts a wide input range of 90–264 V AC, meets RoHS requirements and is designed for installations requiring a compact, high-power adapter with remote ON/OFF and DC OK signal functions. Its compact dimensions are 115 mm (W) × 240 mm (D) × 41 mm (H), and it is supplied in packs of 8 units.

Advantages

The unit provides a high power density in a slim enclosed housing and includes Power Factor Correction for improved input efficiency. Remote ON/OFF and a DC OK signal allow system-level control and monitoring. Compliance with RoHS ensures it meets common environmental requirements, while the wide AC input range supports global mains voltages.

How to use

Install the UHP-1000-48 in a location with adequate ventilation and secure mounting appropriate for enclosed power supplies. Connect the AC input to a compatible 90–264 V AC source, wire the 48 V DC output to the load observing polarity, and use the Remote ON/OFF terminals for system control. Monitor the DC OK signal if integration with a supervision system is required. Follow standard safety practices and local electrical codes during installation.

Recommendations

Allow sufficient airflow around the unit, avoid mounting near heat sources, and ensure the connected load does not exceed the 21 A output rating. Verify wiring and grounding before powering up and consult the manufacturer’s datasheet for detailed protections, derating curves and installation diagrams.
