Description Technical Specs & Manuals
Reliability is already synonymous with the Curtis 1239-8501 AC controller that operates at around 120-170V, mainly because it operates at 120-170W and can also draw up to about 500A, resulting to producing up to about 88Jp and 108ft-lbs of torque. This kit definitely adds great value to any operations and will feature two big features in the market: the idle function feature and the regenerative braking function.

We should add, too, that at even a modest 144 volts, you can make this a safer and lower voltage system alternative for reliable EV miles. With after-market Chill Plate adapter addition that allows for liquid cooling, there’s definitely more power in this that can be seen. Plus, you get more horsepower heavy power curve in this than the previous 1238-7601.
