Medical-grade 1008W 48V power supply

This 1008 watt AC-DC unit delivers a regulated 48 volt output at 21 amps with active power factor correction. It is built to medical safety standards and suits servers, industrial equipment or test benches that require clean, reliable power. The desktop form factor fits standard rack trays or workbench setups.

Sustained 1008W output with PFC

The supply maintains its full 1008 watt rating continuously rather than only in short bursts, thanks to MEAN WELL's thermal design and active PFC circuitry. Efficiency stays high across the load range, reducing waste heat during long compute or charging cycles. Ripple and noise remain within medical-grade limits even at 21 amp draw.

Desktop chassis installs in minutes

The enclosure measures 8.58 inches long, 4.13 inches wide and 2.5 inches high, so it slides into standard 1U or 2U trays without modification. Input and output terminals are clearly labelled on the front face, eliminating wiring guesswork. The only common issue is ensuring adequate airflow around the vented sides when mounted in dense racks.

Questions about this item

How much heat and noise should I expect from the MEAN WELL MSP-1000-48 when it runs at 1008 W continuously?

The unit delivers 48 V at 21 A with active PFC, so sustained full-load operation will generate noticeable heat; ensure the desktop chassis has adequate airflow to keep temperatures in check.

What cables or connectors must I already have to wire the 48 V 21 A output into my server backplane?

The supply provides a 48 V DC output rated at 21 A; you will need mating output connectors and appropriately gauged DC cables to distribute power to your backplane or distribution board.

Will the 8.58" x 4.13" x 2.5" desktop form factor fit alongside legacy ATX or SSI-EEB boards in the same rack?

The compact desktop chassis measures 8.58" L x 4.13" W x 2.5" H, so it can sit beside older boards if your rack or shelf has the matching clearance and mounting points.
