       Thanks for the recon on this one. I went to the website and checked it 
out. From the specs, it is pretty certain that this supply does not use a 
standard switcher topology. I sent a request to the company for further info, 
particularly asking them if they would like to offer any info on what is 
inside the box.

       If they choose to be totally secretive, I guess one of us will have to 
volunteer to buy one for a peek under the hood. Otherwise, if I get a 
meaningful reply, I will post it here for everyone's perusal.

       To me, the most impressive spec is the RFI claim. This is the 
achille's heel of all high-power designs, with new and advanced topologies 
being born every day that further address the RFI problem. But the other 
specs here do not look at all that advanced - in fact, they hint at the whole 
thing being an open-loop design.

       If anyone is interested in discussing the intricacies of switcher 
design, meet me offline.
