Combined power supply for complete rig

[stevepsheehan]

Hi there.

In an effort to tame the tangle of cables, and with an eye to the future, and possible new kit, I'm thinking of making a 12v power distribution system that will power my complete rig, from a single, 240v mains supplied PSU - a 12v DC "ring main" if you like.

I'm trying to get an idea of what sort of power rating I should assume for the cabling. It seems that the mount (a CGEM) could draw 3-4 amps when slewing, but I'm just guessing at other items. I'm assuming the following equipment will be attached together:

CGEM mount, Pegasus Cube focuser, 40mm 12v dew heater strap, 20mm 12v dew heater strap, Altair Astro 183c Pro Tec camera, Startech 7 port 12v powered hub for USB connections, plus in the future, possibly a filter wheel and a rotator.

Off the top of my head, it feels like a 10 amp system would probably suffice; no problem going heavier of course, but I don't want to wander into overkill territory 😉

If there's a basic 12v distribution box available, that I'm unaware of, that would be of interest too.

TIA
