40kW 1000Vdc Bidirectional Isolated DCDC Converter
Product Introduction
BEC1K0135G is a bidirectional DCDC power conversion module specifically designed for energy storage systems, DC microgrids and second-life battery cascade utilization. It enables efficient energy exchange between the battery and the DC bus through a built-in high-frequency isolation transformer. Using third-generation SiC semiconductor devices, it delivers high efficiency, high power density, strong scalability, ultra-low electromagnetic emissions and interference, and enhanced reliability. It stands as one of the world's leading power conversion modules.
