AMP7 toroids

[hawui1]

Quick question, anybody knows how many turns of litz wire one's have to put on each single toroid of AMP7?

[mikechw]

I wrap 32 turns on my T130-2 toroid with my Truepath...

My meter reads around 11uH / 12uH.

It should be the same for AMP7

Yep, the same...

------X-max. can be several meters on any driver, too bad it can be done only once...------

Thanks mikechw and V-bro, I should now have all the info to start the construction.. ;)

I've received a double litz wire for each toroid.
So I've done 18 turn with this extra large cable and there's no space for another turn (it look like to 36 turn).

It's Ok or not?

Hi, you need to keep the two separated. So wind around 30 windings of a single litz wire first. When done put some super glue on it and wind another layer of the same amount of turns and parallel... The board has got four holes for each toroid...

Ok, Now it's clear, tanks

You will notice that at the centre the layers will be right on top of eachother and at the outer diameter they will go in between "like a zipper"....
