B502 series inverter adopts DSP control system which supplies sensorless vector control(SVC) and V/F control.

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. Power range:

Single phase 220V    0.7HP-3HP(0.4KW-2.2KW)

Three phase 220V    1HP-75HP(0.75KW-55KW)
