AC input: 220V single phase
AC output: 380V three phase
Reduce Initial Investment and Operating Costs
Replacing traditional dedicated transformer solutions saves over 60% in initial investment. For example, a 5kW converter driving a three-phase motor significantly lowers costs compared to applying for dedicated power lines. During long-term operation, stable voltage reduces equipment failure rates, extends the lifespan of critical components like motors and controllers, and lowers maintenance and replacement costs.
Cross-Border Equipment Adaptation and Market Expansion
Resolves compatibility issues for 60Hz equipment (e.g., imported machine tools from Thailand or Japan) operating on 50Hz grids. A case study of a multinational corporation’s imported equipment adaptation demonstrates that the converter enabled seamless operation without frequency-related failures, supporting the company’s international market expansion.
