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。

DE12KS31A 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 liquid cooling design,

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.
