EV Series

This series of products is independently developed by our company, specifically designed to provide positive and negative fault protection, as well as short-circuit current protection, for power electronic systems such as energy storage batteries, energy storage inverters, converters, and quency inverters. The products feature high breaking capacity, low Pt, low I²t, low temperature rise and low power consumption.
