I've got a thread going on with my ac to dc power ideas and rigrunner 4008 in mind (also going to be in a nexdome dome + edge 11 hd with dovetail D series on the top, possibly where ill put a 7 port usb 3.0 hub and the rigrunner).
The cem120 of course has its hub with power outputs, off memory i think 2, 5amps and 2 1amp.
Ill have more than this in need of powering, so that lead me to think that doing the rigrunner setup was best (and not really using any of the power off the hub of the 120). Downside of course, defeats the purpose of the power hub and thus at least 1-2 dangling power cables from the rigrunner (mounted either on the mount or on the OTA).
As of now i have power needs:
5amp to the mount
3amp to usb 7 port hub (need at least two 3.0 usb so i have to use the hub too)
5 amp? astrozap dew controller (unsure if 5amp)
3 amp to asi294 pro
future to filter wheel possibly
maybe 5 amp? unsure on amps, to dome rotator control
I know some use power from two dc sources, one to the mount then rest to the other devices. I'm thinking of just powering both the mount and the other devices straight from the rigrunner. I will probably mount the powerwerx 30amp ac to dc unit right on the side of the pier as well (hoping the heat from the unit will stop evening generated condensation, or maybe ill put shields above the dc unit and above my mini pc on the pier side).
So for other cem120 users, how did you end up doing things. Do you have any photos of your layout?
Anyone strictly using the rigrunner option?
