The core technology of the MFC720 heavy-duty universal inverter is still direct torque control space vector modulation (DTC-SVM), which is software-compatible with all functions of the MFC710 series. Compared with MFC710 series, the hardware circuit design has been partially optimized, and the independent air duct and confined space are used in the structural design, which improves the product performance, reduces the failure rate of the inverter, increases the service life of the inverter, and makes the inverter have a higher cost performance and more competitive in the market. Explosion-proof type can be customized according to user requirements.
