1.產品簡介/Product introduction

DE1K8S20 是我公司專門為純電動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，避免重復設計，達到通用化、模塊化的目的；采用數字化處理技術，自帶 CAN 通訊，能夠

向 CAN 總線上報數據，同時接受 CAN 總線的開關機命令，可實時控制和監測 DC 變換器工作狀態。與國

際一流汽車電源廠商完全同步，各項性能指標已達到或超越國際同行水平，無故障運行時間

更長。該系列電源也可適用于需要恒壓、恒流電源的各個領域。

DE1K8S20  is a high-power, small-volume DC/DC converter specially designed for pure electric

vehicles . The converter has wide input voltage range and of 200Vdc to 950Vdc, solving the problem of choosing

multiple DC converters for different vehicle type, avoiding repeated design and achieving the purpose of

generalization and modularization;It adopts digital processing technology, with CAN communication, able to

report data to CAN bus and accept power on command of CAN bus at the same time, monitoring the working

status of DCDC converter in real time. Synchronizing with the world-class automobile manufacturers,

the performance indicators have reached and even exceeded the international peer level, with longer

fault free operation time, can be also applied to field needing constant voltage and constant current

field.
