Industrial 320 W 48 V Supply

The Mean Well SP-320-48 is a single-output AT-type power supply delivering 48 V at 6.7 A for 320 W total. It suits industrial automation, LED lighting systems and test-bench equipment that require a stable 48 V rail with active power-factor correction.

320 W Headroom and Protection Limits

Continuous output is rated at 320 W with universal AC input across the full range. Built-in protections cover short circuit, overload, over voltage and over temperature, so the unit shuts down safely before damage occurs. Loads exceeding 320 W will trigger overload protection, and sustained operation at the limit relies on the internal DC fan for forced-air cooling.

Fan-Cooled Chassis With Remote Sense

Forced air cooling uses a built-in DC fan with speed control to manage thermals under load. The supply includes a remote sense function and ON/OFF control for integration into larger systems. A DC OK signal output is available on related higher-wattage models, while current sharing up to 2400 W is supported on the PSP-600 series, not on this 320 W unit.

Questions about this item

Will the 48V 6.7A output run my legacy AT motherboard and drives without adapters?

The unit delivers 48V at 6.7A with a 320W rating and an AT form factor, matching the voltage and connector style used by older AT boards and peripherals.

How can I verify the supply is operating correctly once installed?

A built-in DC fan spins under load and the 100% full-load burn-in test confirms stable 48V output; listen for fan ramp-up and measure 48V at the terminals to confirm normal operation.

What cables or accessories are included, and what must I source separately?

The power supply ships as a standalone unit with integrated fan and active PFC; AC mains cord, mounting screws and any AT output harnesses are not included and must be purchased separately.
