Product Description

BEDFORD 18.5KW-110KW Sensorless Vector Control (SVC) General Purpose Variable Frequency Inverter 

 
B503 Series  

Product Description

B503 series are widely used in where high require of speed control accuracy, torque response speed and low frequency output characteristics.Using DSP (Digital Signal Processor)control system, vector control without speed sensor, so vector control has greater advantages than V/F control, embedded vector control without PG (SVC) and V/F control together.
