Product Description
Famous BEDFORD years of variable frequency inverter
B503 Series variable frequency inverter
Product Brief
B503 series variable frequency inverter 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.
