final Status report: Thanks to Paul Dove who had a spare 1231C controller he sold me, I'm now back on the road! I'll be accelerating at a much gentler pace and watching my motor amp gauge more, which will be good for my controller (and efficiency), but not as much fun as taking full

On the topic of repairing a Curtis 1221x controller ... When I received my S-10 Blazer conversion EV from the converter (no, I did not make my own. I had no garage, she got the house. But I did have an income, but no time, I was always working), it arrived as a 120VDC T125 system using a Curtis

Jay, I too would steer clear from the Kelly controller. We tested a couple of these when they first started selling in the states (they were looking for distributors). We found that the specs were overstated (possibly peak level at best). Smoked both units well before expectations. I would go

They use MOSFET's in the 1231, if you want to experitment I can give you some free of charge, I get lot's of samples for free and would like to see them used for an EV project. On Sunday, January 1, 2017 8:56 PM, paul dove via EV wrote: It's called an IGBT

Hello Jay, I have been using a 1000 amp at 300 volt rating motor controller from Café Electric for over 15 years. You can purchase them Directly from Café Electric.com who also makes them. Can be interface with any BMS. Back in year 2000, my EV weigh 7050 lbs with ninety 300 ah two volt
