I need to buy or build a polarity reverser (is that the right term?). We have a gyrostabilized helicopter camera system. This runs off 24volts which is normally supplied by the Chopper. I have put together a devise which produces 24volts with a 12volts stepdown that can be used to power the system off mains or switched to 24volts for the helicopter power.
The problem is the power on different choppers is wired differently A+ or B+. I need to build a small circuit which will output 24volts A+ regardless as to which way round the 24volt input side is wired.
regards
