> Hi,
>
> I have drawn up a power supply circuit that will:
>
> (1) Dump the supply voltage very quickly when AC power is turned off
> (2) Dump "returned current" from steppers or servos
> (3) Has a green LED "POWER ON" indicator
> (4) Has a red LED "DUMP" indicator
> (5) No relays. All electronic.
>
> I will breadboard the circuit and test it this weekend. I will post
> the diagram after that if anyone is interested.
>
> The circuit will fit on a PCB that can be mounted atop the main
> filter capacitor via the two cap terminal screws.
>
> You keep your transformer, bridge rectifier and filter capacitor as
> is. This just sits on top of your capacitor and does its thing.
