Engineered for highly demanding industrial machinery, it operates on a standard 3-phase grid power supply (
380V480V AC). It provides smooth sensorless vector speed and torque regulation for both three-phase AC induction motors and modern high-efficiency permanent magnet synchronous motors (PMSM). A core benefit of the premium VSX series is its high-contrast
LCD graphical display with an integrated real-time diagnostic oscilloscope and extensive programmable PLC logic blocks. [
