Title: Art-13 Power Supply Progress Post by: W7SOE on September 10, 2008, 06:16:28 PM I have most of the stuff mounted. The three toroid transformers are for the 28VDC, 400VDC, and the 1500VDC. The other is a choke for the HV. I have the HV bridges on CPU heatsinks, I don't know if I will need a fan yet.
Now to start wiring.... Rich Title: Re: Art-13 Power Supply Progress Post by: W7SOE on September 10, 2008, 06:18:03 PM more pics

COOL!

I added them to a pcb project I was already doing. I have extras if anyone needs them. (and will USE them) 73 Rich Title: Re: Art-13 Power Supply Progress Post by: k7yoo on September 10, 2008, 11:22:04 PM After building up conventional power supplies for my ART-13's I am pretty impressed. I have literally tons of "old style" iron but am very interested in your toroids--where did they come from? Are these new production, surplus, or something you custom made? I want to put one of my ART-13's on my boat but am not too keen about my current bulky supplies. Tell us more!!

I believe this is where AB2EZ is getting his for his modulation transformer experiments. The are relatively inexpensive and substantially more compact. Rich |
