Famous BEDFORD years of open-loose vector inverter 0.75~630kw
B503D Series open-loose vector inverter
Product Brief
B503 series open-loose vector 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.
