| (...) 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)

| | | | | Re: RCX 2.0 Power Supply
|
| (...) 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)
| | | | | Re: RCX 2.0 Power Supply

| (...) 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 (...)

| | | | | Re: RCX 2.0 Power Supply

| (...) 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)
