Power Range: 10kW to 300kW
Isolated type: The insulation monitoring threshold value on the fuel cell system side and the high voltage power battery side can be set separately without affecting each other, which can well protect the fuel cell and vehicle power battery ;
Isolated type: with short circuit protection.
Isolated type: Rated efficiency is 95%
Non-isolated type: SiC is used as the core component, and the average efficiency is ≥98%.
With a good capability of dynamic regulation, it can adapt to the large fluctuation range of the load and fulfill the maneuverability requirements of the fuel cell vehicles.
