B503D Series
 
Product Brief
B503D series power saver 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.
