The circuit should draw about 1.0A-1.25A. Sounds like a good idea if I can determine a good, cheap trigger circuit. Thanks,

-BobHere's one I use that I don't think has been suggested. I use a MOSFET in series at the input, arranged to switch off on over-voltage. I didn't notice what current your circuit draws, but if you use a T0220 with a few milliohms resistance you get only a few millivolts drop when on. Because you switch it off on over volts, no power is dissipated. Use something like 100V device and it's bulletproof. To protect against reverse voltage you have little choice other than a reverse diode across the input. BTW What is the total current drain of your circuit?
