George,
What is a packetflux 5ch PDU? I can't find anything on their site
except 4 and 8 port injectors.

I have some PacketFlux 5Ch PDUs. I've found the current measurements
to be fairly accurate. One has an AF24 on it and measures 1020mA, so
49 watts. Others with Exalt ExtendAir G2-11's measuring 490-520mA, so
24-25 watts. And a pair of SAF Lumina 6GHz HP radios both about 825mA
= 39.6 watts while the radios themselves say about 870mA and 40.4
watts, so.. close enough. All of these are fed from the regulated
output Traco BCMU360's in 48V mode. I love the 5Ch PDUs +
GigE-POE-APCs for +48 backhauls. No fuses to worry about. And slightly
higher power than a typical POE injector will handle.

Kind of interesting, I was just checking some of ours... I have one
site, where there are two AF-5x plugged being powered from a MikroTik
hEX PoE, so they both have the exact same power source, similar cable
lengths, etc. and one is showing 8.1 watts and the other is 10.5
watts. The interesting thing, is that the one that's drawing more
power actually has less load going through it, and judging from the
MAC address, is also slightly newer. I don't know how accurate those
MikroTiks are at measuring current (wouldn't surprise me if they're
far from accurate), but I would expect them to at least be kinda
consistent.

I really thought I remembered seeing an AF5X about eighteen months
ago, drawing 16-17W from the wall, but I could be wrong or the watt
meter that it was plugged into was grossly inaccurate. This newer
model of kill-a-watt seems to be better.

Yeah, I think that's pretty consistent with what the AF-5X radios
have always used. The AF5 (not X) and AF24 do use a lot more power.

Yes. All my AF5X use ~10W. UBNT AC use 6W and older MT 11n use
3-4W. SAF is 30-35. PTP600 is 50.

I think you are thinking of the AF24 which cranks 50W all the

Provisioning a new AF5X link here on their AC PoE injectors
before they go out to the field. Something interesting I've
noticed, and maybe I'm not remembering right, but it seems that
the newer AF5X use less power than the older ones.
This unit with its ubnt default PoE injector plugged into a
kill-a-watt is measuring 11 watts. There's no traffic going
through it, but as I recall an AF5X uses pretty much the same
amount whether or not it's under load, since the AF architecture
is constantly sending/receiving frames whether or not they have
an ethernet data payload.
