| (...) 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 (...)

| (...) 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)

| (...) Indeed, the input capacitor of the RCX is rated 10V, so I would not do that for a too long time. This 1000µF capacitor, used to keep memory during battery exchange, is directly connected to RCX board supply input. By the way, this capacitor is (...)

| (...) You need to check the voltage while the PS is under load. Pretty much every power supply puts out more when the load is low or nothing. Has to do with loads of factors, but mostly quality of the PS (and (thus) internal resistance of the PS) (...) (20 years ago, 15-Sep-04, to lugnet.robotics, lugnet.trains)
