Product Description

Product Overview

For bidirectional conversion, it is possible to step down the voltage from the power supply side to the battery side, or to step up the voltage from the battery side to the power supply side.

Maximum current: 200A
Input voltage range: 280–700V _DC
DC-side voltage range: 0～Input Voltage (Buck Mode) / Input Voltage～720V _DC (Boost Mode)
