Centrifuge Vector Frequency Inverter 3AC 15HP ( 11KW ) 380V ~ 460V
High-performance current vector technology for easy drive of
induction motors. The technical and performance problems
encountered so far in equipment such as cables, machine tools,
metal products, petrochemicals, natural gas, lifting equipment,
pulp and paper, textiles, printing and dyeing, ceramics, etc. can
be easily solved.
High performance, high quality, high power density design, and
significant improvements in ease of use, maintainability,
environmental friendliness, installation space and design standards
further optimize the user experience.
