Ummm… Martin? You just confused me to all ends of the earth.
Yes, I do have a budget. I just want to know what to do. I am no stranger to high voltage. In Thailand the #1 cause of death is bad electric install. I made my building install <gasp> a ground wire! Took away the shocks, but leakage is still bad for high meter bills.
I guess I don't get why I can't take a 30 breaker from mains, rectify it, ripple smooth it, set up a series of high ohm resisters sich that across each one would be near 17v, enclose it with an earth ground, and expose the 17v terminals.
I truly do not want to build a 220 to 17v transformer for high current. I don't know enough to design a switching PSU of 1kW each.
I can't change to the TEC1-12706 which I could use standard 12vdc power supplies because the space requires a certain wattage removed per sq cm.
If I didn't have these grouops, I would do as above and not feel too worried, but this is a commercial outcome eventually.
So, what ia it that can be supplied? Pigtailed isolation transformers?
