Hi Jan

You are doing good work. As long as the electrical design remains the same, it does not worry me at all what shape and size the PSU board ends up.

Regards

Gary..

Hi Jan

That looks good as far as the circuit is concerned, I cannot see any errors.

Are you going to just have solder pads on each board to solder the wire jumpers between boards or will you also have terminal blocks like Con 1 to Con 5 for these connections.

Do you have any idea of the physical board size for this design and will they both be the same size.

If they are to stack on top of each other , allow for holes in boards to take screws or some form of spacers to physically support boards. Also watch how high the boards will be fitted with large caps and diode heatsinks if stacked, as some people's chassis designs may not be high enough.

Regards

Gary..

Hi Gary;

You can see the temporary layout in post 79.
I intend to fitt the boards with both terminal blocks and Fastons. for ALL connections, also interconnections.....

We have the choice between the long pcb in post 66 (lenght 35 cm!!!!), and the modular in post 79. The advantage of the last layout is that it can either be stacked or placed side by side (and the board with caps can be fitted in a 90 degree angle to lower the hight).

I think that the options of the last version would fitt most builder best........

Hi Jan

Thanks for the reply, sorry I missed the layout in post 79. I agree that this is a good solution for all builders.

I like your work so far.

As I said before I will take at least 10 of these for current projects and future ones.

Regards

Gary..

Sad to inform you all, that the stackable solution as shown in my schematic in post 79 doesn't seem to be very practical when layouted.... Connectors everywhere for forth and back...

A solution could be just to make the long version in post 66 "breakable" in the middle, so you can divide this in 2 and either stack them or place them side by side.....
