Product Description

Bedford AC - AC 220V/380V 1phase /3phase General Inverter

Specifications

B503 series inverter adopts DSP control system which supplies sensorless vector control(SVC) and V/F control.

VFDs

Product Brief: B503 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.

Single phase 220V Input 0.75KW ~ 2.2KW
Three phase 220V Input 3.7KW~55KW

Three phase 380V Input 0.75KW ~ 630KW
