The Curtis 1206-4301 Controller is a 36V, 350A DC Series Motor speed controller for electric golf carts and related electric vehicles, using ITS as the throttle input.

1206-4301 is mainly used as a replacement product for the original controller of E-Z-GO electric vehicles, suitable for vehicles using DC series excited motors, ITS throttle, and non PDS, non DCS drive systems.

The rated voltage of this controller is 36V DC, with a current limit of 350A. Compared to some original 250A controllers, the 350A version can provide higher current capacity and a certain current margin, while also helping to improve the vehicle’s power and torque performance.
