恒流、恒功率狀態(tài)自動(dòng)轉(zhuǎn)換充電方法，有效節(jié)省充電時(shí)間；具有有源功率因數(shù)校正功能，對(duì)

電網(wǎng)低污染；輸入和輸出電壓范圍寬；采用 CAN2.0B 通信協(xié)議；具有智能充電功能、智能監(jiān)

測故障告警保護(hù)功能、燒寫、故障查詢等功能；同時(shí)內(nèi)置 12V 供電池管理系統(tǒng)喚醒信號(hào)電源。

具有與充電樁連接的控制導(dǎo)引功能（可選）等。

該款電源專為新能源汽車高壓電池充電而設(shè)計(jì),與國際一流汽車電源廠商完全同步，各項(xiàng)

性能指標(biāo)已達(dá)到或超越國際同行水平，無故障運(yùn)行時(shí)間更長。該系列電源也可適用于需要恒

壓、恒流、恒功率充電的各個(gè)領(lǐng)域。此充電機(jī)僅支持對(duì)電池充電。

DA3K3M13-70C 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. The charger only supports charging the battery.
