Hi Owel,

I would like to know the voltage that should come in the connection AC1,CT, AC2. I bought another transfo than yours and I would like to know if it have enough power.

Thanks

You need at least 18VAC between AC1 and CT and AC2 and CT. And 36VAC measured across AC1 and AC2.

If you used a lower voltage rating than that, your phantom power may not get to exactly 48V. It's not the end of the world anyway, even if you didn't get 48V.

use this formula to approximate... Volts ac x 1.414 = DC voltage (unregulated)

Ok thanx for the help. And I have a final last question, just for security purposes and to be 100% sure I'm not doing something wrong.

I have 3 outputs to my transformator:
1. 0V--7V, 6A (WHT/ORG)
2. 0V--13V, 6A (BRN/GRN)
3. 0V--13V, 6A (YEL/BLK)

So basically, I have 26VA, 26VA, 4.2VA.
Now my question is, for the connexion on the PSU, I would have to connect the BRN and YEL wires with the CT, and then say the GRN wire to AC1, and finally the BLK wire to AC2 right ?!?

And does it matter if I have 26-0-26 instead of the 18-0-18 minimum or 22-0-22 you suggested ??

Thx for answering, if I got this one right...I'm ready to power up !! hehe

I don't think your transformer will work.

You basically have a 13-0-13 transformer (with an extra 7V) output.
