So I've got the hard work done on the 200 amp 50 VDC supply.
Believe it or not making those #6 AWG battery cables was like hard labor. Crimping them with a small hand crimper then soldering them....sucked.
So the next phase of this is two get the step-start built, and I have to run a second 240v line to the shack. I'm going to use 2 each 240v @ 30A lines to run this supply.
I'm still thinking about my options for mounting all of this. I have a large 4U computer server case I could use...it'd be kinda nice for this as it has built in fans already as well as dust filters (a must here!). That's probably what I'm going to use.
It took me about 48 hours (with sleep mixed in there :-) to modify all of these and create the jumpers.
