Actually I'm just trying to figure out what you're trying to do with PoE.

Create a product line of aerospace instrumentation, small boxes that
can be placed right next to loads or motors or sensors and need only a
cat5 cable for power and computer interface.

The current practice is to put a PXIe or VME crate in a rack and
interface it to a computer (maybe $10K) and then buy modules and then
design and buy fabulously expensive custom cables out to the field.
Tha cables can cost more than the things that they connect. And rack
space is often very valuable.

USB4 is likely to become the only wired interface needed on most future devices for short distance communication.
Almost 250W power capability too if you believe this page:
https://en.wikipedia.org/wiki/USB4
But other sources say up to 100W.
You'll still need an RJ45 connector and maybe optional wart connector of course.
And anything else a specialist application needs.

The power supply module is just the test bed for the first box in the
family. Most modules would only need a few watts, but this one allows
some thermal characterization too.

We're about to go public with the concept. Wanna see the intro?
