Feature: 1. Application: Widely used for heavy duty golf carts, personnel transports, burden carriers, and other utility vehicles. 2. OE Number: Programmable motor controller replace part number is 1268 5403. Please double check the OE part number of your item before ordering. 3. Performance: Programmable DC motor controller offers smooth, silent, cost effective control of motor speed and for torque. 4. Speed Adjustment: The speed sensor input allows excellent closed loop control for regulating vehicle speed. Unique braking parameters allow simple, intuitive deceleration tuning. 5. Function: Help electric vehicles brake and store some of the braking energy in the power battery, improving vehicle performance. Specification: Item Type: Programmable DC Motor ControllerMaterial: ABS and stainless steelOE: 1268 5403Application: According to the command of gear, throttle, brake, etc., the electric energy stored in the power battery will be converted into the electric energy required by the drive motor to control the driving status of the electric vehicle such as starting operation, in and out speed, climbing strength, etc., or will help the electric vehicle brake and store part of the brake energy into the power battery.
