MV-VFD of Wolong-Rongxin Company adopts multi-cell cascaded multi-level technology solutions. With high efficiency, high power factor, no special requirements for motor, no special requirements for cable, without the harmonic interference, etc.

In addition to the characteristics above, different with other manufacturers, the Wolong-Rongxin MV-VFD still has the following aspects:On the motor side, the drives provide almost perfectly sinusoidal motor current such that there are no concerns regarding overheating in the motor or torque pulsations on the motor shaft.

The RMVC 5100 family of drives is particularly suitable to retrofit applications as well as applications requiring long cables to the motor, the cable length could be 1000 meters at maximum, without filters used.
