SKU CH-MMEY-FSMJD

Delivers 12 V at 40 A with active PFC, forced-air cooling and full-load burn-in testing

  • TypeAT
  • Delivers 480 W continuous power from a 12 V 40 A single output
  • Active PFC corrects power factor across the full universal AC input range
  • Built-in DC fan with speed control provides forced-air cooling under load
  • Comprehensive protection covers short circuit, overload, over-voltage and over-temperature
  • 100 % full-load burn-in test validates reliability before shipment

Industrial Single-Rail Power Unit

The Mean Well SP-480-12 is a 12V 40A 480W single-output supply with active PFC and forced-air cooling. It accepts universal AC input and includes short-circuit, overload, over-voltage and over-temperature protections. A built-in fan-speed control and remote on/off function support integration into rack or cabinet systems.

Suits integrators building 12V DC distribution buses

This unit targets engineers who need a regulated 12V rail for industrial equipment, LED arrays or battery-charging rigs. It is not suited for desktop PC builders requiring ATX connectors or multiple regulated rails. Buyers needing redundant current-sharing above 2400W should evaluate other architectures.

480W continuous at 12V with active PFC

The supply delivers 40A continuously at 12V from a universal AC source with built-in power-factor correction. That single-rail rating decides whether the unit matches the load budget of the target system.

Questions about this item

Does the SP-480-12 include a mains cable and mounting hardware, or must they be purchased separately?

The unit is supplied as the power supply only; a mains lead and mounting fixings are not included and must be sourced separately.

When should I choose the SP-480-12 over the SP-320 or SP-750 models?

Choose the SP-480-12 when you need 480 W continuous output at 12 V with 40 A current, built-in remote sense and ON/OFF control, and active PFC in a forced-air cooled enclosure.

What does the 480 W rating mean for continuous operation in my system?

The 480 W rating means the supply can deliver 12 V at up to 40 A continuously with active PFC, forced-air cooling and full protection circuits, and it has passed a 100 % full-load burn-in test.
