  • Comprehensive protection covers short circuit, overload, over voltage and over temperature
  • 100% full load burn-in test validates 312W reliability

Industrial 312W Single-Output Unit

The Mean Well SP-320-24 is a 24V 13A AT-type power supply rated for 312W continuous output. It suits system integrators and maintenance engineers who need a reliable DC source for automation cabinets, test benches or retrofit projects. The universal AC input accepts full-range mains without manual switching. Active PFC reduces harmonic distortion on the supply network.

Forced-Air Cooling With Fan Control

A built-in DC fan provides forced-air cooling across the chassis. Fan speed control adjusts airflow to load and temperature, limiting acoustic output during lighter duty cycles. The unit has passed a 100% full load burn-in test at the factory. Protection circuits cover short circuit, overload, over voltage and over temperature events.

Remote Sense And Parallel Expansion

Remote sense compensation corrects voltage drop across long cable runs to the load. An ON/OFF control input allows external sequencing without interrupting the AC feed. Current sharing supports up to 2400W when up to four compatible units are paralleled. A DC OK signal output simplifies monitoring in supervisory systems.

Questions about this item

How do I mount the Mean Well SP-320-24 and what wiring step is often missed?

Mount the unit on a flat metal surface using the four chassis holes to aid heat transfer. The step often missed is connecting the remote-sense leads to the load terminals; without them the 24 V output drops under the 13 A load.

Which part will need replacement first during continuous operation?

The built-in DC fan with speed control is the only moving component; its bearings typically wear before the electrolytic capacitors, so plan a fan swap after several years of 24/7 use.

What thermal limit appears first when the supply runs at 312 W for long periods?

Forced-air cooling handles the 312 W load, but if the intake air exceeds the unit's rated ambient temperature the over-temperature protection will shut the output down before any other limit is reached.
