What's the breakdown voltage on the insulation for a 22 AWG wire?

Using that kind of power scheme, and 48 volts, you're talking about
over 500 watts? No way!

Yes, I do, the manufacturer of the jacks I use rates them at 1.5 amps.
But you better not plug them in under load...

All one polarity? Where's the drain? You really think you can get
1-1/2 amps through each of those teeny little RJ45 connections?

Let me be more clear.
The circuit that is pins 4,5 (+), and pins 7,8 (-) is one circuit.
Total of .75 amps.
The circuit that is pins 1,2 (-), and pins 3,6 (+) is one circuit.
Total of .75 amps.
That puts 375 milliamps on each pin and each wire. That's because
the power/current that is going in on pins 7 & 8, has to return on
pins 4 & 5. You can't double that.
Possibly more than I would be comfortable with anyway.

Half an amp per wire on one chart, 3.5 amps on another chart.
Heating and insulation temperature rating are going to be the
limiting factors there.
Jacks I use have a 1.5 amp rating per pin.
So, I think you can get 12 amps total if the cable is short enough.

Each pair is one half of a power circuit. So there are 4 halves.
There are two issues; how much current can each wire carry, and
how much current can each connector pin can carry.

There are four pairs. AF5x and the H in 24vh or 48vh POE ports
of Netonix do power over all four pairs. Speaking with Ubnt
support last week, AF5x should ideally do four pairs when possible.
48v (0.75*4a) = 144 watts

At 48 volts, and .75 amps per pair of power wires, that would

Just noodling here.

For the record,

<http://store.packetflux.com/powerinjector-plus-sync-gigabit-version/>
says: 1A per port maximum power. (48 watts at 48 Volts)
So.. is the electronic over-current protection the 1A limit?
Or is this just outdated info? Pretty sure it's >1A because
I've "tested" it (cable leaking water into the GigE-APC, the
port didn't trip, and the card was hot as hell).
I was also unaware that Cambium won't be supporting
sync-over-power on the 450m. I imagine the ringing/bounce
issue killed that idea due to the high power consumption.

The current products should power the 450M just fine. The
rating is 1A per pair per port, so at the 48V you're good
up to 96W.

The 450m pulls 70 watts. The current
SyncInjector/PowerInjector+Sync is around 1A max per

the new aux port version SyncBox Junior.

Shouldn't the sync over power for the 450M be the

How is the 1u sync injector coming?

A question for Forrest mostly. Have you
come up with a timing product for
the 450m AP yet? If not, have you got a
timeline for release?
