I assume that you can provide a cad drawing in DXF or DWG for the placement of the diodes. What is the AC voltage range that you need? Does the battery need to be rechargeable or simple cells (AA, etc) that can be replaced by the user. Do you want assembled tested boards, or will you be doing this, and if so how many boards do you want. The on/off switch..does it need to be located remote or on the board? Bid price does not include components or blank boards if assembly is desired.
