DA40KM44Ais an OBC switching power supply 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.
