I need to drive some equipment that requires 12 volts (car battery) at 14 amps. Initially it will require 10 amps while heating and then intermittently to maintain temperature on the heaters. I want to have something external to the equipment and preferably UL approved. I would prefer if it was available in the USA but this is not essential. Of course cost is, as always, a major consideration. Any ideas. TIA, Peter -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
