I want to use three of these finished boards in my car (don't laugh too hard). There is a DC-DC power supply I've found online that will put out 38vdc, but that's all. What are the power requirements for these boards?

Your best bet is to use a power inverter. These are sold commonly in various power output ratings. What the inverter does is convert the 12 volt DC to 120 volt ac. This way you can put TVs and DVD/VCR players in your minivans for the kids to watch on long trips, or camping, or whatever. I once had a 10 channel strain gage conditioning unit and a data logging computer powered with one at a remote site and had no problems. The lower wattage models plug into the cigarette lighter, but bigger ones need to be wired directly to the battery posts.
This way you can just build the amps without worrying about designing some kind of brute force power supply to give you the 400 dc volts for the amps. It also keeps the high voltage safely tucked inside whatever chassis you are planning to house the boards in. :sunny:
