AS510 AFE VFD products, with the use of advanced controllable rectification technique and coupled with LCL filter, achieves the active rectification and provides constant DC power and energy feedback for the system. One or more VFD units may operate in the DC bus to form the multi-motor drive system of four quadrant operation, providing an ideal solution for the motor control application in various occasions.

* Technical features

1. Active rectification technique to reduce the reactive power, with the power factor close to 1.
2. Four-quadrant operation, with energy feedback function.
3. The DC bus is more stable.
4. Current harmonics less than 4% in full load.
5. Standard LCL filter and charging circuit
6. Perfect heat dissipation structure design.

* Application industries
Harmonic suppression occasions: pump, wind turbine and compressor
Energy feedback occasion:crane, winch, pipeline, hoist, test bench, turbine motor and other complex drive systems.
