Open-frame triple-output power supply unit, green PCB with soldered components

Mean Well

Mean Well PT-65A 60W Triple Output Power Supply 5V 12V -5V

SKU CH-W7VZ-1GVNP

Delivers 60 W across three rails at 5 V, 12 V and -5 V for industrial open-frame builds

  • TypeAT
  • Triple-output design delivers 5 V, 12 V and –5 V from one unit
  • 60 W total power handles demanding industrial loads
  • Channel 1 supplies 5.5 A at 5 V for logic circuits
  • Channel 2 provides 2.5 A at 12 V for motors or relays
  • Channel 3 offers 0.5 A at –5 V for analogue biasing

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 about this item

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.
