| | | | (...) 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)

| | | | | (...) Not nearly impossible. It just requires a little more intelligence be put into the power supply. All the regulated power supplies my company produces contain a circuit called a down programmer. This circuits job is to discharge the filter (...)

| | | | | (...) 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)
