SDJ series (10kw-25kw) AC controller is a driver developed for AC electric vehicles in low & high voltage, supporting 48V to 144V. As the drive equipment of high reliability and large torque asynchronous motor, designed with four quadrants vector control method, it can control the motor speed & torque precisely. It is widely used in pure electric passenger car, electric forklift, low-speed A00 class passenger car, electric sightseeing vehicle, electric logistic vehicle, etc.

• (1) The controller adopts the German DSP, an international mainstream digital drive as a core control chip, which helps to build a good platform for motor control algorithm.
• (2) By using the high power MOSFET tube for power device, it can realize the efficient energy conversion.
• (3) Multiple safety protection for CAN interface and safety certification management of lithium battery BMS.
• (4) Support short circuit protection (phase - ground, phase - phase, phase - source), overload, over temperature, over voltage protection.
• (5) A reliable & flexible regenerative brake technology can improve the driving mileage, and meet the needs of customer.
• (6) Using micro-motion technology & slow descent and hill-holding technology for steep slope, more powerful climbing ability, stable hill-holding, stronger start-up.
• (7) Adopt excellent optimization algorithm & frequency 0 to 300 HZ, to reduce noise and vibration amplitude.
• (8) Perfect fault protection function, the buzzer reminds all kinds of faults, it’s convenient maintenance.
• (9) Adopts CAN-bus technology to reduce wiring connected, the parameter can be adjusted and it’s programmable online.
• (10) Adopts compatible design to make the volume smaller and the weight lighter.
• (11) Simplify the installation and debugging steps.
• (12) High reliability, low maintenance cost.
• (13) Parameters or software could be customized as customer’s requirement.
