| (...) Sure it can be done, but it is very uncommon. I seriously doubt that any wall-wart (even very good ones) do it. I have a very high quality wall-wart. It puts out 2A at 3 to 24V, is very stable at the whole range from very little to full load (...) (20 years ago, 16-Sep-04, to lugnet.robotics, lugnet.trains)

| (...) A friend did the mistake for me... but I had to repair a few of his RCXs! The connector he used to plug an external supply was prone to be shorted (on RCX side) when he unplugged it. It was only several fuses later that we understood the (...) (20 years ago, 16-Sep-04, to lugnet.robotics, lugnet.trains, FTX)

All the regulated power supplies my company produces contain a circuit called a down programmer. This circuits job is to discharge the filter (...)

| (...) It is nearly impossible to build a power supply that puts out the rated voltage when there is no load. Most will put out too high a voltage (like you have seen), some just shut down. To meassure the voltage of a PS, shorten it with a 1000 Ohm (...) (20 years ago, 15-Sep-04, to lugnet.robotics, lugnet.trains)
