Found this site: http://rotarypistonengine.com/8.html

A 144V/1000A controller lists for $1069.95, but other than CGI, no
pictures of one.

He also states:
"12v to 5000v up to 5000 amps voltage controller special order:
All models are tested to run at the power rating only, do not go above
the rating this will destroy the controllers!
WARNING!! higher power controller are very deadly and could kill!
We will help you build your own power systems or new engine design."

Anyone have an opinion on this?

I don't know ANYTHING about this guy or his products, but...

I wonder if his windmill design (on the same page) is any indication of
his engineering skills.

Well he responded to an email and promises to get a real picture and
more data up soon.

The one line that sounds hokey is "we have a trade secret that will
allow up to 92% drain on the transistor without overheating...." But
They sound simple, no micro.
I will keep an eye on this one.

>Hi Mr. Shanab,

> I will have the real picture up soon and all the data need.
>For low price controllers if we use IGBT the cost would go much higher,
but with the technology we use we can us Mosfet at lower cost.

>Temperture is very important to Mosfet and IGBT we have a trade secret
that will allow up to 92% drain on the transister without over heating,
most controller have >heat problems that effect the power output on the
transister.
>This unit run a 5k to 10k pot at 2kz to 15kz and up to 100% full power
>Comes with voltage limiter and overheat protection.

>Not programable what a waste of time and add extra cost to make!
>We make basic high powerful controllers only.


>A 300v 1000 amps is full output without over heating or untill your
batteries are dead!
>I will have a 150v controller on youtube soon, you will see the true
power for less price then the Zilla's.


>Tom.
