Industrial Open-Frame Supply

The Mean Well PT-45C is an AC-DC switching power supply built on a standard PCB format for industrial and embedded applications. It delivers three regulated rails in a compact open-frame design suited for equipment builders and system integrators.

Triple Output Capacity

The unit provides 43.5W total across CH1 at 5V 3A, CH2 at 15V 1.6A and CH3 at -15V 0.3A. This headroom covers typical analog, logic and sensor circuits but leaves no margin for high-current motor drives or multiple add-on boards.

Bundled Free Gift

A complimentary accessory is included in the shipment alongside the PT-45C unit. The extra item adds convenience for bench testing or prototype wiring without changing the core electrical specification.

Questions about this item

Will the PT-45C's 5 V / 3 A, 15 V / 1.6 A and -15 V / .3 A rails share a common ground with my existing AT chassis?

Yes, all three outputs reference the same return path inside the open-frame unit, so they share a common ground with any AT-style case wiring.

How can I confirm the PT-45C is regulating correctly once installed?

Measure 5 V ±5 % on CH1, 15 V ±5 % on CH2 and -15 V ±5 % on CH3 under load; the built-in over-voltage and short-circuit protection will latch off if a rail drifts out of spec.

Does the package include mounting hardware or mating connectors for the PT-45C?

The box contains the PT-45C power supply and a free gift only; screws, standoffs and output connectors must be sourced separately.
