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。
DE12KS31 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 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.
