Humm design creep time I see. Just get one miricle running and out the
door and they want the Stars and Moon to go.
Yea I can agree on some parts but let be serious here Roger.
How long do you expect the List driven Bit kickers to take to get a
Micro controlling the PFCs??? HUmm how about like a couple of weeks ago.
The whole growth path was to get the basic power processor up and
running and in hands BEFORE we did a micro fully programmable unit.
Kinda get the watts right then add the brains.
And Oh yea keep the bills paid while I am doing it.
I have charged Floodeds AGMS, NIcads, NiZn, and NiMH. There are about 4
folks doing thier micro interface. So... that's being covered.
Water proof??? Not likely, We have found that letting the water drip
out is safer in the long run than sealing it in. And I have done 3 water
cooled PFC20s. So I have that covered also.
The main features of the PFC20 line are 120 to 240 operation. PF
corrected. NOTE that the flexable inputs voltages are a product definer
in thier own right. Also living on 40 to 80 Hz power keeps them on where
the Brusa has some issues with NON 50 Hz power.
The other main thing is Price.. I have heard that the Brusa is $3800 to
$5800, I am not sure which. But that's WAY out of line for a home built
EV.
So price
Input voltage flexability, and frequency freedom.
And POWER.
And the 12 to 420 volt output range.
The other issues will be taken care of in Due time.
A programmble interface, Palm, or 232 will happen in weeks.
Iso is a $300 issue at your local Platt electronics outlet. Cutler
Hammer Line isolation transformers. Cheap industrial, and Well very
heavy metal.
I have things the even Brusa doesn't.
The gym awaits... I need it!!
