Seems all I can find online are the specs for the new AC versions but not the older AREDN compatible ones.
I'm trying to determine if they're AT or AF compatible as I need to change my POE Extender strategy at one of my sites.

Neither 'af' nor 'at'.
I hope this helps,

To perhaps save you some time, this is an AirMAX device, and all such devices are passive POE, 24V. They do not support 802.3af or at.

Thanks guys.
My 525+ foot run of Cat5e has been working well for the past few months but we recently had a pretty major heatwave and it appears my passive POE Extender failed because of overtemp, causing any "serious" amount of data through the system to cause the PBE400 to reboot, apparently from excessive voltage drop.
So I'm re-engineering my run to use a 48 volt system (as opposed to the current 24 volt one) with a POE AF adapter/voltage reducer at the Powerbeam and an active extender.
I'm curious - do you know how high the temperature got? The Ubiquiti POE adapters are spec'd to 104F. Was it higher than that?
Also, as you may already know, the maximum cable run for Ethernet of any type is 100m (328') at 68F. So 525' is well beyond the spec. It's possible that may be a contributing factor wrt your issues. It's not like the signals stop after 100m, but you will get signal degradation and some voltage drop. The voltage drop will probably not be a problem, as Ubiquiti devices will run well at much less than 24v, but signal quality may be an issue. Using shielded Ubiquiti Toughcable will certainly help, as will the fact that it is a single end-to-end run, so no collisions. Also, make sure your POE adapter has an earth ground, as that is part of the EMF protection. Plenty of people will tell you they run lines over 100m all the time. I have. It may very well work for your situation, but there's a lot of math involved that we never really think about, and errors start to get introduced. "Your mileage may vary."

You're missing the part about using a POE EXTENDER. The particular one I'm using is from POETexas and is a passive one, not active and is spec'd at a max ambient temp of 113 degrees F. I have it installed in a weatherproof box as the Extender was designed for indoor use and I suspect with our heatwave (4 days of 100+ temps) and the box is exposed to sunlight, the temps inside probably skyrocketed and damaged the Extender. My discussions with POETexas confirm this. and hence the observations I made as posted in Post #5.
As part of my re-engineering, the new Extender is rated at 150 degrees F and, with some shading I'll provide, should be content. Also, it doesn't need to be installed inside the box as it is designed for outdoor use.
