Not slagging your efforts Rich, just pointing out that (as far as I know) you aren't selling PFC's with brains yet. I know there have been efforts underway to get programmable brains built for it, which is why I said "yet". However, I haven't heard anything more about it, and until you are advertising such for sale and have done enough testing on it to be confident offering a warantee to someone plugging it onto a $10k pack of exotic batteries, it just doesn't exist, no matter what you may have in the lab. Once you are offering it for sale, I'm sure it will be a worthy competitor to the Brusa and others. > The main features of the PFC20 line are 120 to 240 > operation. PF corrected.

But Victor asserts that the PFC20 has nothing on the NLG5xx in this regard. > Also > living on 40 to 80 Hz power keeps them on where the Brusa has > some issues with NON 50 Hz power. Tell me more; I'm rather surprised to hear of a switchmode PFC charger that can't handle at least the nominal 47-63Hz range, especially considering that Brusa chargers have been being sold into North America for some time. > The other main thing is Price..

Perhaps, but Victor wasn't talking of a homebuilt EV, necessarily, but a kit for those wishing to produce an EV worthy of being called an EV1 replacement. > Iso is a $300 issue at your local Platt electronics outlet. > Cutler Hammer Line isolation transformers. Cheap industrial, > and Well very heavy metal. True enough, but rather a messy way to bandaid isolation onto the product. The Brusa claims 92% efficiency at 230V input, 3.6kW in and 300V output, weighs 6.9kg (15lbs) and includes the isolation feature. It's also 5" tall with a 10"x10" footprint. Those are pretty tough features to compete with when you sit it next to a PFC20 + 60Hz isolation transformer and try to sell it to someone as an onboard charger. > I have things the even Brusa doesn't.
