I'm looking for some help from people more electronics-inclined than myself.
I have my mount, ZWO cameras, and mini PC (which runs off 12v) connected to a rigrunner, which is powered by a 30-amp 12v power supply. The mount and cameras are connected to the PC over USB. There are no 12v cable runs longer than 6 feet.
I power on the PC and cameras first to do polar alignment, and then power on the mount. When I power on the mount, the PC shuts off. It powers back on without a problem, but I don't like that this is happening and would like to get to the bottom of it.
This is where a lot more equipment information could be revealing.
For example, a lower specification Intel NUC will run on "12 - 19 volts + or - 10%". If running on a "12v" supply, it doesn't take much of a voltage drop to witness a cut off. I had a load of problems with cheap Asian batteries that start at 12v but soon deplete to as little as 9.6V.
Whilst most devices will only draw the amperage they require, if too great, some will cut off. I tried running my camera (seeks 2A, Focuser 1A, NUC 3A) using a 12v 10 Amp AC/DC supply and my NUC didn't like that. I now use two 5A supplies and all is fine. It could be 30A is just too much.
Just read note 126.96.36.199 of my Intel NUC specification. This states that the maximum current rating is 10 Amp. You need to sort out power if your mini PC is similar.
