First thanks to all for their input so far.
Second regarding the use of a battery and charger, that was my first thought as well but there are some practical safety concerns with having a battery in this location as it is a power source that cannot be de-energized.
Some background:
I need an 80 amp 12 volt DC source to run a motor for about 1 minute ever few days. Yes a battery would be perfect but I can't have one. I am trying to prototype a device that could go into production so price is a real concern but complete field ready design is not required at this point. There are 1+ Kw DC power supplies for servers readily available but all the ones I've seen in this power range are for 220 VAC input which is no good for me. I have been looking around for a 110 to 12 volt transformer in the 1+ KW range but have had no luck finding one. I know they exist I just don' know where. With that component the rest of the problem becomes pretty straight forward.
Here is the question(s) I probably should have asked:
1) Any thoughts on a cheap way to get 80 amp 12 volt DC out of 110 AC? (We're after power here not precision)
2) Does anybody know where to find a 110 VAC-12 VAC transformer in the 1+ KW range?
3) Given how cheap ATX power supplies are is there a reasonable circuit that I could use to allow two to be used in parallel?
Thanks to all in advance.
