We had an extended power outage a couple months ago on a tower with two AF-5x radios, and the batteries got drained down to nothing. I don't remember exactly what the voltage got down to before we lost contact to the tower, but I know it was well below 20v - something like 16-17, if I remember right. ________________________________ From: ubnt_users-boun...@wispa.org [ubnt_users-boun...@wispa.org] on behalf of Steve D [bigd...@gmail.com] Sent: Thursday, January 05, 2017 3:31 PM To: Ubiquiti Users Group Subject: Re: [Ubnt_users] Airfiber 5x power consumption
Oh, that is bloody fantastic. Thanks for the responses guys. I'd love to hear from Ubnt guys about the low end power and whether they can they safely hit 20v in a worst case scenario. We really try our best to avoid ever going under 24v but it's nice to have wiggle room for days when everything goes stupid. And much, much love for the wide range of input voltage because I can totally see ourselves eventually moving to 48v if we ever did this again. -Steve On Thu, Jan 5, 2017 at 1:22 PM, Mathew Howard <mat...@litewire.net<mailto:mat...@litewire.net>> wrote: I've measured similar power consumption... the spec sheet is definitely on the high side. I usually figure 8 watts for planning purposes, but I haven't ever seen them actually draw that much. According to ubiquiti, the input voltage is 19v to 53v now, but I don't think they are 802.3af compliant. ________________________________ From: ubnt_users-boun...@wispa.org<mailto:ubnt_users-boun...@wispa.org> [ubnt_users-boun...@wispa.org<mailto:ubnt_users-boun...@wispa.org>] on behalf of Josh Luthman [j...@imaginenetworksllc.com<mailto:j...@imaginenetworksllc.com>] Sent: Thursday, January 05, 2017 2:46 PM To: Ubiquiti Users Group Subject: Re: [Ubnt_users] Airfiber 5x power consumption Power consumption Wall is 123vac. Amp meter says 0.07a. 8.61 watts. This is the factory POE. POE spits out 24vdc. Amp meter said 0.23a. 5.52 watts. I waited ~10 minutes after it booted to look. They were definitely associated. It's running 33dBm EIRP @ 5240. 6 watt radio I would *NOT* call power hungry at all. They were 24v radios on the first shipment, there's a specific MAC address range (very small). These days they're 24-48 volts. It's to the point where Netonix is removing 24vh (power on 4 pairs) because AF5x was the only radio that uses it and it isn't necessary but for a small number of existing units. I think the cut off is 20v?

Anyone able to tell me how true this is? Looking to bolt something onto a solar site, and I was under the impression the airfiber line was power hungry. Plus, I could have sworn they were af802.3 compliant so 48 volt. This isn't a case of someone copy pasting spec sheets from airmax radios, is it?
