的电压，专为新能源汽车设计。 电源采用风冷设计，与国际汽车电源厂商同步，各

项性能指标已达到或超越国际同行水平，运行时间更长。该系列电源也可适用于需要

恒压、恒流电源的各个领域。

DE12KS23 C is a DC/DC converter with features of high efficiency, big power, small

volume and reliable working method, adopting advanced pulse width modulation technology. With

functions of input over/under voltage protection, output over current protection, over temperature

protection,etc. Achieving constant voltage and constant current automatic transfer. It could

converter high voltage battery voltage to low voltage used for low voltage device and charge for

low voltage battery, specically designed for electric vehicles. Adopting air cooling design,

synchronizing with the world-class auto 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.
