the fact the video had some kind of hard dance music was completely disturbing.

I couldn't watch it....

What would be scary to test...and I do have to say that is small wire on primary side for 32A, at least it looks to me like that

Thanks for vid, and other like that?

Default 32A in primary side wire

Hi Luka

It's true! That small wire with 32A (127VAC primary) charge. It's so much, I don't believe this!!

Thanks

Sandro

32A is RMS input current from mains. Current across primary windings is only approx. 13A at full load.

This power supply is extremely similar to my 0-15V 0-125A prototype, including synchronous rectification and the dual output section approach.

It seems that they forgot to include the voltage and current-limit adjustments, though...

Thank you very much.
