1.產(chǎn)品簡介

DE3KM17B系列  是我公司專門為純電動(dòng)汽車量身打造的一款大功率、小體積 DC/DC 變換器。

變換器具有超寬的輸入范圍，可工作在輸入電壓 200Vdc 至 950Vdc 之間，解決了不同車型需選用多種

DC 變換器的困擾，避免重復(fù)設(shè)計(jì)，達(dá)到通用化、模塊化的目的；

采用數(shù)字化處理技術(shù)，自帶 CAN 通訊，能夠向 CAN 總線上報(bào)數(shù)據(jù)，同時(shí)接受 CAN 總線的開關(guān)機(jī)

命令，可實(shí)時(shí)控制和監(jiān)測 DC 變換器工作狀態(tài)。

DE3KM17B-650S28RC is a high-power, small-volume DC/DC converter specially designed for pure

electric vehicles. The converter has an ultra-wide input range, and can work between input voltage

of 200Vdc to 950Vdc, which solves the trouble of choosing a variety of DC converters for different

models, avoids repeated design, and achieves the purpose of generalization and modularization.

It adopts digital processing technology and has its own CAN communication, which can report data

to CAN bus, and at the same time accept the switch command of CAN bus, which can control and

monitor the working status of DC converter in real time.
