DA6K6M20 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. 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.
