Brad, Recall that P=V^2/R, so it seems as though applying the appropriately sized & load-rated resistance network across the pairs delivering power, and then measuring the voltage dropped across that resistance network would give you a reasonably good indication of whether the appropriate power is being delivered to the load. For 60W in seems like you might choose R~75 Ohm on each of two pair, but I’d encourage you to double-check my arithmetic.

I have some jacks that pass the installer’s Category Certification, but are not passing the appropriate PoE to bring the APs online. I would like to be able to load test for 802.3af, 802.3at, and 802.3bt (at both 60W and 90W), as appropriate. I assume I would need to be able to set the load to apply (in Watts) and see the voltage level at the Powered Device. The usual constraints apply. Cheaper, but reliable is best.
