Hi folks,
Thank you for the replies you sent me.
Regarding the HV transformer, some things that I could gather from your replies:
- not use a center tap on the secondary
- look for hypersil or other good quality iron
- good copper wire insulation
- good layer insulation
- primary taps are a good idea, but them should not go too far.
- secondary taps are not a seven-headed beast, but I wont be able to change
that
on the fly
So, I wonder as having these specs for my price quotations:
primary:
0 - 200 - 210 - 220 - 230
secondary
0 - 2400 - 2600 - 2800 - 3000 - 3200 - 3400 (no center tap)
I believe that will make room for future projects using the same transformer.
73 TU,
Felipe
