Where are you getting a volt or two? Ohms law is pretty settled science.

I'm saying you're going to see a volt or two loss even if it's a ~10 foot run by the time you actually get it to your Tik from the PSU.

Yep, shorter the distance less the drop no matter what the gauge.. assuming tiny power needs of course. On Mon, Jul 10, 2023, 4:11 PM <[email protected]> wrote: But he said “a couple of feet”...

If it's 23awg cat6, with two wires on each polarity at 100m you'll see some drop though.

(couple feet) .008 * .25 = 2 mV Yes, put in 60 volts in and get 59.998 volts at the Tik. Not a very effective way to drop some voltage...

If you put 60v on one end and run even a couple of feet off you're not getting 60v into the Tik is my point.

I guess you want that wire to stay ice cold.

Or some built in resistance - like a length of copper wire :) On Thu, Jul 6, 2023 at 10:28 PM castarritt <[email protected]> wrote: I'm not an EE, but wouldn't something like a 1w 10ohm resistor in series with the fiberbox solve this?

Mikrotik says Max power is 57V. I have a power design using a DRS240 that has max power of 57.6V on vBoost.
