1.产品简介

DE3KM17B系列  是我公司专门为纯电动汽车量身打造的一款大功率、小体积 DC/DC 变换器。

变换器具有超宽的输入范围，可工作在输入电压 200Vdc 至 950Vdc 之间，解决了不同车型需选用多种

DC 变换器的困扰，避免重复设计，达到通用化、模块化的目的；

采用数字化处理技术，自带 CAN 通讯，能够向 CAN 总线上报数据，同时接受 CAN 总线的开关机

命令，可实时控制和监测 DC 变换器工作状态。

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.
