Powersupply

[Kongen]

I have 4 2*33volts/500va trafos lying around. I have been looking around for a new amp and got my eyes on the tripath TP0104 modules from www.cadaudio.dk which runs on 2*95volts. I was wondering if it is possible to series connect the secondaries to get 66v ac which would give something like 90v dc. As far as i know it should be possible...? what happens to the va-rating when series connecting secondaries rated at 250 va each? Anyways the idea is to make two monoblocks each with 2 trafos (i think the tripaths also need some 12v and 5v supplys but that shouldn't be a problem). The strereo tripath powersupply sold by cadaudio is rated at 1200va. Give your thoughts...

It's very much possible to do what you suggest.

You have 4 x 500 VA now and you will get still 2 kVA with this manuevre = 1000 VA for each monoblock

more supply

Hey I was just thinking that the two secondary windings have to be connected as 0-33-0-33 and then i'll use the left 0 and the right 33 and connect the other two... or willl this not be an issue?


many thanks for your help...

Correct. And of course the primaries go in parallel. If one of the primaries or secondaries is reversed, you will have close to zero between the left 0 and right 33, so then you need to reverse one of the secondaries (or one of the primaries, doesn't matter).

But mixing the primaries up shouldn't be a problem since all af my trafos are from the same manufacturer. So its just a question of putting the secondaries right... when i come to think about there might be a description printed on the trafo telling which secondary is which...

Thanks a lot guys...
