Description
Sinopak MVVFD includes integrated structure and split-type structure based on capacity. The integrated structure is adopted in low capacity MV VFD and the split-type structure is adopted in high capacity MV VFD. In terms of an integrated machine, which is compact in size, phase-transformer, power units, control systems, and power frequency bypass are fully integrated into one cabinet; In terms of a split-type machine, phase-transformer, power units, control systems and power frequency bypass are assembled in separate cabinets in which are combined on the spot.
