DA3K3M17E is an OBC switching power converter.The charger adopts advanced all-digital 

resonant frequency modulation technology, which has high efficiency, high power, small size and 

reliable operation. The charging mode adopts constant power,constant voltage and constant current 

automatic state transition, which effectively saves charging time. With active power factor 

correction, zero pollution to the grid, wide input and output voltage range, using CAN2.0B 

communication protocol. With intelligent charging function, it has intelligent monitoring fault alarm 

protection function,programme function and fault inquiry function; it also has built-in 12V 

independent auxiliary power supply for power supply of car battery management system.
