Famous BEDFORD years of china VFD manufacturers
B503 Series china vfd manufacturers
Product Brief
B503D series china vfd manufacturers adopts DSP control system which supplies Sensorless Vector Control (SVC) and V/F control. Comparing with V/F control, the performance of DSP has greater superiority, which consists of inbuilt SVC and V/F control accuracy, it is widely applied to high speed control accuracy, rapid torque response and high performance at low frequency.
