DA6K6M22A 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, program me function and fault inquiry function; it also has built-in 

12V independent auxiliary power supply for power supply of car battery management system. 

This power supply is specially designed for charging high-voltage batteries of new energy vehicles. 

which is completely synchronized with the world-class automobile power supply manufacturers. 

The performance indicators have reached or exceeded the international peer level, and the fault-free 

running time is longer.
