D03 controller

Brief Introduction:

Vehicle control technology is integrated into this series controller to provide efficient control of 

the three-phase AC motor for the vehicle power drive system, providing the 

most cost-effective design for vehicle developers and providing a flexible, comfortable and 

safe handling experience for vehicle drivers and passengers.

●Applicable to Induction motor and PMSM

●To gain higher power density and overload capacity,SMD MOSFET and aluminum 

plate cooling technology are adopted

●The power supply of control signal can be provided by12VDC or power battery

●High-performance vector control algorithm to achieve full speed range of motor 

speed and precise torque control, improving vehicle power performance and comfort

●Flexible parameter adjustment function meets theexcellent

●Multi-functional I/O terminals, meeting the requirements of different applications

●Integrated high voltage pre-charge circuits, improving the all-in-one design

●Natural cooling, force air and liquid cooling are adopted, covering overall power range

●Customized software available for meeting different requirements of customers

●CAN bus communication and software update by computer programming

Typical Application:

●Applicable to all-electric or hybrid vehicles powered by rated voltage of battery 60 ~ 144 VDC

●Applicable to short-distance passenger cars, sightseeing cars, logistics vans, 

sanitation vehicles andmaterial handling vehicles and other electric vehicles
