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.

There are two issues; how much current can each wire carry, and how much current can each connector pin can carry. bp <part15sbs{at}gmail{dot}com> On 11/14/2016 11:59 AM, Josh Luthman wrote: There are four pairs.

(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 Or is this just outdated info?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.

What you could do for now is a GigE-POE-APC and the new aux port version SyncBox Junior. On 11/14/2016 12:34 PM, Matt wrote: Shouldn't the sync over power for the 450M be the same as PMP450i?

Have you come up with a timing product for the 450m AP yet? If not, have you got a timeline for release? Sam -- -- Sam Lambie Taosnet Wireless Tech. 575-758-7598 Office www.Taosnet.com
