Supplier: Variable frequency drive and soft starter, and also an electrical automation product solution ., both of low voltage and medium voltage, such as control panel, plc control system, progress control system.
Product Structure
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.
