DSD DC Hub Power Supply

[Daf1983]

I've recently ordered a DC Hub from Deep Sky Dad like the one from the link below:

https://shop.deepskydad.com/product/dc-hub-2/

It doesn't come with a power supply, so I need to order a 12V DC supply which can supply at least 8A, which I can then connect to the mains. I'm not overly keen on spending £60 on the pegasus astro PSU, and there are some available on ebay/amazon for about £20, but not sure if these would be any good. 

Any recommendations would be welcome!

I have a DSD power hub and had the same q. I've been using https://www.harrisontelescopes.co.uk/acatalog/power-supply-10a.html#SID=1667 for a year now.

No idea if it's better than the cheaper ones on eBay, but I've had it for over a year and it's still working.

Thank you, exactly what I was looking for! It's worth the extra £10 over the ebay option for the peace of mind of knowing it works!

I just noticed that this has a cigarette lighter type connection, how do you then connect that to the hub?

What about this if you can put in the shed and run 12v to mount

I do have a shed nearby, but I tend to move my mount around the garden depending on what I'm shooting, so I can avoid street lights/houses/trees etc. So it would probably not be suitable

Forgot that - I just chopped the cigarette lighter end off and swapped to the right size connector for the DSD. You can buy them there the wires screw in so no soldering required!

I use plenty of those solderless connectors! I always dab a bit of hot glue on the screws and wire clamps though so no moisture can get in.

Im pretty sure the DC hub input socket is 5.5 x 2.5 while all the outputs are 5.5 x 2.1. Mine is anyway, unless he's changed the design since.

 

Edit: Just checked the link and it does appear to be a new version with 5.5 x 2.1 input, same as the outputs. Ignore the above!

Ok, that's definitely an option. Do you mean something like this...

Yeah - I got a pack of 10 male/female from somewhere. They're cheap but the issue is the postage costs!

Mine is 2.5mm for the input - but I got it over a year ago. 

I like the fact I can't accidentally get them the wrong way around!
