POE & RB750-PBr2

You never did tell us how long the cable run is to power the MINI. Keep in mind that the voltage drop depends on cable length and wattage load.

I power one of my MINIs over a 300 foot run from a WS-24 VH port and the MINI has all the remaining 5 ports powering kit. In cold weather when the heaters come on in the 48V cameras, I would get low voltage alerts but they kept on working. I think Eric recently adjusted the alert low voltage thresholds so I probably won't see alerts next Winter.

Ubiquiti now has a 54V PoE brick that I am considering trying as the 4 extra volts for sure will keep me above the alert threshold. I did consider the 56V Tycon PoE but if/when there is no load on the MINI, it would have alerted on over-voltage. I think Eric also adjusted the high voltage threshold so it would no longer alert on 56V.

I think you would be fine to power it from the VH port. If you need more volts to compensate for line loss, then either the 54V Ubiquiti or the 56V Tycon will work.

The cable length is a couple of hundred feet, however, it's a DC powered setup (no AC PoE bricks) with no Netonix swtich (no VH ports) which is kind of my problem.

To confirm, when you say the 56V Tycon will work are you talking about this one?

Thanks

No, that model. You need the following one that uses all 8 wires for power, not just the 4 wires that one uses.

perfect - thank you for the clarification.
