Operating at 36-60V, the Curtis 1236e-5621 AC controller draws up to about 550A, which produces up to about 27HP and 70 ft.-lbs of torque. What makes this controller work efficiently is when its applied to lightweight applications, including dirt bikes, small boats, golf carts, ATVs and also microcars. This comes with extra features like regenerative braking and an idle function, which works even better when used at 48 volts because it offers a safer low voltage system built perfectly for reliable EV miles. There is also the fact that this controller comes with an after-market Chill Plate adapter suitable for liquid cooling. Just take note that the harness and display of this controller are sold separately.
The Curtis 1238e-6521 AC controller functions at 48-80V, but it can easily draw up to about 550A, resulting to a torque production of about 47 HP and 69 ft-lbs. Whether you’re using this kit in basic and portable applications from small boats, dirt bikes, ATVs, golf carts, microcars and kei cars, you can be sure that it still retains its powerful features, including the idle function and regenerative braking systems. If you have this kit at 72 volts, you may use it in systems with lower voltage system, giving users the most maximally reliable EV miles today. An added benefit is that this kit comes with an after-market Chill Plate adapter for more robust liquid cooling system.
The great thing about the Curtis 1238e-7621 AC controller is that it can operate at 72-130V, draw up to a torque of about 70HP and 115ft-lbs, and will still work completely in either medium-sized cars and lightweight units or vehicles. The powerful features of this kit include a regenerative braking and idle function system that makes them ideal for a safer low voltage system even at a modest 130 volts, giving any user a high-capacity level of reliable EV miles. Added to this featured package is a Chill Plate adapter that can let liquid cooling run without interruption and with its harness and display separately offered.
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.
