Outdoor power supply

[Ricker]

Does anyone have recommendations for a 12v 10amp regulated power supply suitable for use outdoors?

I need this to power an EQ6, zwo 1600 camera dew bands and zwo eaf

For my garden pier, I use a standard ATX power supply that not only powers the local computer, but the mount, hubs, cameras, focusers etc.

For use at star parties, I use both a large (heavy) linear supply and the smaller monolithic 'bricks'.. All of which can be found on the bay\amazon etc.

Given that you would need to run a mains cable anyway have you considered keeping the supply indoors and running just the 12v line.

This does need to be a thick cable due to the current involved but I have done this using 2 core 1.5mm rubber cable , though it is a good idea to raise the voltage to 13.8v , this allows for some voltage drop and the EQ6 is usually happier on the slightly raised voltage.

 

a distribution box at the mount end can give multiple outputs and some of these can be regulated 12v ones

(I use cheap Chinese prebuilt 12 regulator boards to drop the 13.8 down to a limited 12v output , available from a common auction site)

 

 

There are plenty good quality "ham" radio 13.8v supplies ideal for this.

I have 2 units both bought 2nd hand

the Maplin one is still often available  2nd hand (on here or elsewhere)

  , the other is a premium 25amp supply but I got it as a good deal used.

 

Both are linear supplies (not switchmode) , for long cable runs linear is preferred. (switchmode can generate rfi on long cables)
