I am finishing up the design of my DIY power supply and I wanted to run some of my design thoughts with the forum for some feedback/confirmation that I doing this correctly.

1) I am thinking of mounting two Weber WPDLXFMR-1 transformer (8 11vac windings and 1 9vac winding) in my chassis. I was planning on running the primary windings in parallel from the 120v main to power the two transformers.

2) I would like to have 18v for one of the dc outputs, so I was thinking that after the legs get converted to 9vdc, I could take two of the 9vdc legs and twist them together to get 18v. I am correct in my thinking on this?

Thanks,
Scott

I believe that should work since they are isolated circuits. That's what I had planned to do anyway...Let me know how it works :).

Sorry to resurrect this one from the dead, but I just wanted to see if running the transformers in parallel worked for you? I was thinking about doing the same thing in an upcoming project, but I cannot find a concrete yes or no on whether it is ok to do that. Does anyone know? Thanks!

I used a 2u rack enclosure. The Weber transformers are rather large.
