Industrial triple-output supply
The Mean Well PT-65A is an open-frame AC-DC unit built to the AT form factor. It delivers three regulated rails from a single 60 W budget, making it suited to legacy industrial gear and test benches that still expect a 5 V, 12 V and -5 V combination.
5.5 A on 5 V, 2.5 A on 12 V, 0.5 A on -5 V
The 5 V rail carries the bulk of the load at 5.5 A while the 12 V rail supports fans or drive motors at 2.5 A. The -5 V rail is limited to 0.5 A, so it only suits low-current bias or reference circuits. Combined draw must stay within the 60 W envelope.
AT form factor constraints
Mechanical mounting follows the classic AT footprint, so it fits existing chassis cut-outs without adapters. The design omits power-factor correction, which keeps cost down but means the unit draws non-sinusoidal current from the mains. No remote-sense or parallel-operation features are provided.

Questions sur cet article
Will the 5 V rail at 5.5 A and 12 V rail at 2.5 A run legacy ISA cards and a vintage motherboard together?
The PT-65A delivers 5 V at 5.5 A, 12 V at 2.5 A and –5 V at 0.5 A simultaneously, matching typical AT-era load splits for ISA slots and motherboard logic.
How can I confirm all three outputs are live after wiring the open-frame unit?
Measure 5 V on CH1, 12 V on CH2 and –5 V on CH3 with a multimeter under load; each rail should stay within ±5 % of its rated voltage.
Does the box include mounting hardware or only the PT-65A board?
The package contains the PT-65A open-frame supply plus a free gift; screws, standoffs or a chassis are not included and must be sourced separately.
