DE2000S9GF  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.
