however on a side note I'm very well versed in UPS systems. a lot of them use AC-DC-AC convertors and i have some friends that are UPS technicians. I've worked on a few myself as well a few years back. So i'm still gonna do some research and talk to a few of them.It is new ground as no reviewer has ever even bothered with baseline efficiency rating across different mods & manufacturers. It is possible that different build resistances would place vastly different loads on the chip.
Interesting though.
I also on top of my oscilloscope have access to amprobe DM-3 multi test meters through my job. I used them to help size my solar system on my house i know those things like the back of my hand lol. plus with the oscilloscope and a multimeter i should have more then enough testing equipment
