Power Supply Circuit

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.
