[Wieser Scott]

I'd like to check out your conversion.  Would you mind if I came over
for a look?

You can give me a call if you want @ 293-3949.

Thanks,

Scott

yes.  heat sink and a fan.  

The max amps the motor will recieve is more dependent on the overall
design of the whole system than the rating of the controller.

I have run the Geo at 96, 108 and 120v, for at least a few months at
each voltage.  Each time I increased the voltage I liked the performance
better.
Having the option to increase your voltage to 144 is something you
should consider.

off the line response is not at max amps in a curtis controller, there
is a throttle curve that controlls that.

Of you really want off the line response go with higher voltage.
The 120v maxes at 66kw and the 144v controller is 72kw.


 Do you know

No, I think I am the only one in the group with the curtis controller.
