Hi Brian, The 2 piece AC adapter uses a Switched-Mode Power Supply, and my one here says 100 to 240V input.
these power supplies work in a clever way that basically involves switching on and off very, very quickly, in order to get the right output voltage. Since the mains voltage is going up and down 50 or 60 times a second, if you switch at the right part of that cycle, for the right amount of time, you can get pretty much any output voltage you need. This is all done automatically, so you can plug it in anywhere and get your 12V output without having to worry about exploding BrailleNotes! On the down side, because they switch on and off very fast, they can produce annoying noise, especially when plugged in next to old hi-fi equipment - like mine, for instance! regards, Andy. ---- Andrew Riden Software Development Engineer HumanWare Ltd. 11 Mary Muller Drive, Christchurch, New Zealand.
