LS-MV inverter
Model No.: LS-MV (Hight Voltage Inverter)
Introductiom :
Long Shenq Electronic has always been focusing on the R&D and high-efficiency utilization of green energy sources. The LS-MV medium voltage inverter is an IGBT medium voltage inverter developed and manufactured by Long Shenq Electronic based on the leading power electronics technologies of Emerson Network Power . With the SPWM (Sinusoidal PWM) control, it realizes variable frequency speed regulation control on the medium voltage motors, so as to enhance the variable-speed operation, increase the control level, power factor and operating efficiency of medium voltage drive system, meet requirements on technical control, reduce motor energy consumption and realize energy saving and environment protection.
