Open-frame triple-output power supply PCB, green finish

Mean Well

Mean Well PT-65B 63.5W Triple Output Power Supply

SKU CH-N6S4-FBSEQ

Delivers 63.5 W through triple outputs of 5 V at 5.5 A, 12 V at 2.5 A and -12 V at 0.5 A in an open-frame AT form factor

  • Product typeAT
  • Triple output delivers 5 V, 12 V and –12 V from one unit
  • 5 W total power supports compact industrial systems
  • Channel one supplies 5.5 A for logic circuits
  • Channel two provides 2.5 A for peripheral loads
  • Channel three offers 0.5 A for negative-rail needs

Industrial Open Frame Power Supply

The Mean Well PT-65B is a 63.5W AC-DC switching supply with triple regulated outputs. It delivers 5 V at 5.5 A, 12 V at 2.5 A and -12 V at 0.5 A from a single PCB-mount unit. The design targets embedded systems and industrial equipment that need multiple rails in a compact footprint.

Suited for multi-rail embedded builds

Engineers integrating custom control boards, test fixtures or legacy AT-style systems will find the three voltages convenient. The open-frame construction requires a suitable enclosure and external safety isolation, so it is not appropriate for direct consumer desktop replacement or applications needing power-factor correction.

63.5W total power budget

The combined output is rated at 63.5 W across all three channels, so the available current on each rail depends on the load sharing of the other two. Verify that the sum of your actual loads stays within this limit before committing to the part.

Questions about this item

How do I install this open-frame power supply and what step is often missed?

Mount the PCB using its standard mounting holes, connect AC input to L and N terminals, then wire each output channel to its load. The step often missed is verifying the -12 V polarity on CH3 before powering on.

What maintenance or replacement will this unit need over time?

The internal electrolytic capacitors on the PCB will age; plan to replace them after several years of continuous operation to maintain stable 5 V, 12 V and -12 V outputs.

Which output hits its current limit first under sustained full load?

CH3 at -12 V is rated for only .5 A, so it reaches its limit well before CH1 at 5.5 A or CH2 at 2.5 A when all three channels are heavily loaded.
