144W Power Supply for the WS-6 Mini

[rconaway]

We have been using these for quite a while and with the temperatures in Phoenix, they have held up pretty well. They also just plug in which is nice.

Rory, what is the voltage reported on the status page with those? Are you not happy with the Netonix PA-50V-65W?

I only power mine with 50V through the PoE and due to polarity protection diodes suffer a 1.4V drop that way so would not want to start off 2V lower at 48V. In fact I am tempted to try the Ubiquiti 54V PoE brick.

Really good price on that BTW.

You can feed the WS-6-MINI up to 57V with no problem just keep in mind what ever voltage you supply it that voltage is provided for the 48V POE option

Anything over 60V will result in smoke even just a hair over. STAY BELOW 60V

I think I asked you about using 56V and you talked me out of it. In really cold weather when the heaters kick in on the cams the voltage was dropping 8V to about 42V so the 56V would be 48V then. Even without the heaters, my wattage draw goes up at night when the IR LEDs come on. Right now during the day it sits around 45V so losing about 5V.

I don't recall if the barrel connector also drops the voltage by 1.4V so 56V at the barrel versus 56V on the far end of a 300 foot CAT5 run is not the same.

If it was up to me I would spec 48V to 56V, Dave the Engineer is the one worried that if we spec 56V then people will say ah 60V is only 4V more and 60V is the upper MAX limit before smoke can occur.

IKWYM, give an inch and they take a mile.

Old thread, but I thought I'd respond to the "are you not happy with the 65W supplies" question.

FWIW, we have experienced problems in the field with the 65W power supplies on a switch where all ports are powering UBNT radios.

It could be high heat inside cabinet at site, samples we purchased not providing the specified current output or some other factor. But with 4 ports powering 24V radios, a write cycle (config or firmware update) will occasionally cause the switch to drop POE causing radios to reboot. In one case the radio became borked and needed to be reloaded via TFTP.

We have gone to using UBNT 80W 50V POE if WS-6MINI is standalone and not being powered by a Netonix. No problems thus far. We don't know if 65W is not enough power / margin for our situation or if the 65W supplies we received are out of spec.

I came here to post exactly this question. Designing to power some 6 Minis off our -48 plants using TP-DCDC-4856G-VHP which actually output a hair over 56V. Will be running four LTU rockets off of each one.

Thoughts/drawbacks of running the LTU rockets at 24V vs 48 (actually 56+/- .4V) powered by the 6 mini? We have been running an LTU rocket directly off the TP-DCDC-4856G-VHP and it runs fine.

We have a few of the UBNT 54v injectors out in the wild back from when there was a supply issue getting the recommended injectors. They've been running fine. I'm pretty sure at least one location I am running 48vh to an AF-60 LR on it.
