Passive POE switch.
I would love to see something like the WS mini or the WS 12-250-dc but in a passive POE with support down to 10V

The WS-12-250-DC can run all the way down to 9V input.

Re: Passive POE switch.
Yes but not all of the equipment on my tower needs the full 24Volts. I could save some precious energy on my solar installations by eliminating the loss from up-converting from 12v and by eliminating the cooling fan (with the WS mini form factor).

Re: Passive POE switch.
So then basically you want Vout to follow Vin like Routerboard or TS5 does. No regulating, no upconverting.

Exactly, but with the performance of the netonix. Ive used the Mikrotik RB, Tycon and Ubiquiti switches and none of them have done as well as the netonix has.

Re: Passive POE switch.
I could have seen a use for this in the past. Newer ubiquiti radios don't run as low as older ones did though. You really need something like 16v to reliably power a RocketAC. I've seen RocketM still working at around 12v, but not the AC line.
A decent switching boost converter with mosfets is 90%+ efficient. Consider the added cost in 10% more batteries vs any feature you find on a switch.
Anyway, I'll take the variable input and some extra draw over running APs under-volted. When the volts start to drop on your battery bank it's nice to be able to keep comms up to send an alert to see flaky radios IMO.
