AC VARIABLE FREQUENCY DRIVE
Product Brief:
B502 series inverter adopts DSP control system which supplies sensorless vector control(SVC) and V/F control.Comparing with V/F control,the performance of SDP has greater superiority,which consists of Built-in SVC and V/F control,it is widely aplied to high speed contro l accuracy,rapid torque response and high performance at low frequency.
Main Features:
. Control mode: sensorless vector control,V/F control,Torque control
. Start-up torque:0.5Hz/150%(SVC)
. Built-in breaking unit for 0.4kw to 11kw.If need to stop rapidly,please connect the brake resistance directly.
. Mult-step(8 steps)speed control: PID control,Traverse control
. Offer 4 multi-functional digital inputs,2 analog inputs,1 relay output,1 analog output,1 open-collector output.
. AVR: Can output constant voltage automatically when input voltage is fluctuating.
. Offer RS485 communication interface.
. Standard Modbus.
Applications:
B502 series(Output frequency range is 0~400Hz)
Textile machinery,Plastic machinery,Light industry,Pharmacy machinery,Fan,Water Pump,Air compressor,etc.
Power range:
Single phase 220V 0.7HP~3HP(0.4KW~2.2KW)
Three phase 220V 1HP~75HP(0.75KW~55KW)
Three phase 380V 1HP~860HP(0.75KW~630KW)
