Rigrunner Topside Power Distribution
« on: 11:58:03, 08 September, 2016 »
As some people would attest to, I have very slight OCD when it comes to cabling  :yes:. As such I have been looking for a flexible solution to distributing 12 volt power top-side i.e. without running multiple power cables up to the mount head.

I saw a RigRunner being used for just this purpose so took the plunge and ordered one.

The RigRunner is a lightweight box with a number of PowerPole sockets. PowerPoles are sturdy and modular and cannot be reverse polarity connected. Each connection is separately fused. At 40 Amp, they easily cope with the sort of power we are used to having to run around.

I can now have a single USB and Power connection to topside and have enough outputs to power camera, filter wheel, USB hub, focuser and dew controller.

The only real downside is that they are not cheap but tidy cabling does come at a price.

Chris,

Just wondering why you haven't rigged up a distribution box based on an ATX power supply ?

You'd get three separate +12v outputs, as well as one -12v, four 5v, one 5v stand-by, and five 3.3v outputs (as well as nine grounds) on a standard supply, with an additional three 12v, one 5v and three grounds on one with the extra 8-pin connector.

A little work, and you could create a distribution box to your exact specifications ... not to mention putting in as many USB power sockets as you need.

Weight and needing then to run mains to topside, the RigRunner weighs a few ounces so can happily be mounted on the scope. In the obsy and at star parties I run everything from a 13.8 volt bench supply well away from the mount. There is a bit of loss over the long cable but with a starting voltage of 13.8 its not an issue. On the MX, the 12 volt supply and USB are cabled through the mount so there are no cables to snag at all. On an EQ6, not having USB and power distribution taking place topside, leads to lots of cables with an inherent risk of snagging and catching the wind!

Slight OCD !!!!!!   

Looking at it Chris looks smart,  What about dew ?

As setup at the moment the Sharpsky controller handles that  stuff but in the obsy I have a two channel controller that just plugs into the RigRunner, the second fuse from the left is higher rampage to deal with that. I have a 12 volt USB hub mounted on the other side.

Well ... the ATX & dist-box could be low-down, with only the relevant cabling going up; or just the dist-box up.  The latter would be pretty light (the box would probably weigh more than the cabling & sockets !).

Hence the second suggestion; or even having a sub-dis-box up top - have the main break-out in the main box, and run a wrapped set of cables to a small one with the sockets in ?

Anyway - ideas for others, as you're happy with what you have :)

Looks a nice setup Chris.
Shame about the black cable ties not being level !!!!!!!!!!!!!!!

Don't forget the red & orange fuses not matching the nice purple ones  :nerd:

Tsk, I'd replace that black screw just above the fuses - unlikely to be stainless so it will go orange within the year.

No attention to detail.  :laugh:

I have lots of cables going up to the OTA, I just trained them all to behave themselves :-) My mount used to do a couple dozen meridian flips during a modelling run with no problems (then it twigged I should change the running order of the list of refinement points using increasing AZ - now it only needs around 6 per run). However, whatever you find works best is good with me :-)

I notice you're at Kelling. I've had an issue with my mount hub pro which has had me wasting valuable imaging time last winter trying to track down a guiding problem. Your cable tidying solution seems perfect and considerably cheaper than replacing the MHP. I'm not very electrically savvy so I'd like to pick your brain as to whether I can change existing connectors for dew controller, USB hub etc. Can I look you up?

Will you be bringing th above setup with you?
