Product Description
Famous BEDFORD years of bedford frequency drive

B503 Series bedford frequency drive

Product Brief
B503 series economic 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.


Main Control Function

Control Mode: Sensorless Vector Control (SVC), V/F Control
Overload Capacity: 60s with 150% of rated current, 10s with 180% of rated current.
Starting Torque: 150% of rated torque at 0.5Hz (SVC).
Speed Adjusting Range: 1: 100(SVC)
Speed Accuracy: ± 0.5% of maximum speed (SVC)
Carrier Frequency: 0.5kHz~15.0kHz bedford frequency drive
Reference Frequency Source: Keypad, analog input, serial communication,
Multi-step speed, PID and so on. The combination of multi-modes and
Switching between different modes can be realized. Bedford frequency drive
Torque Control Function: Provide multiple torque setting source.
PID Control Function.
Multi-Step Speed Control Function: 8 steps speed can be set.
Traverse Control Function.
Non-Stop when power is instantaneously cut off.
Speed trace Function: Start the running motor smothly...5.
Key: User defined shortcut key can be realized. Bedford frequency drive
AVR: Can output constant voltage automatically when input voltage is fluctuating.
Offer RS485 serial communication interface. Standard ModBus.
Over-troque Detection Function. Bedford frequency drive


Applications:
B503 series bedford frequency drive (Output frequency range is 0~600Hz):
Textile machinery, plastic machinery, ceramic machinery, electric machinery, numerical control machine, foodstuff processing machinery, Light industry, Pharmacy machinery, Fan, Water pump, Air compressor, etc.

Power Range:
Single phase 220V 1HP~3HP(0.75KW~2.2KW)
Three phase 220V 1HP~75HP(0.75KW~55KW)
Three phase 380V 1HP~860HP(0.75KW~630KW)
