DF5000 series Medium Voltage VFD is one type of high relibility, high efficiency, high energy saving, zero pollution Medium voltage high power variable frequency device. The equipment source side power factor is higher than 0.95, no reactive power compensation is required. The system efficiency is higher than 96%, input and output harmonics satisfy IEEEStd 519-1992 and GB/T14549- 93 requirement, no harmonics pollution to electrical grid, and at the same time the excellent output voltage waveform also eliminate the problems like heating of motor, additional stress, etc., largely increase the lifetime of the motor. The high availability of each type of customer interface, modular design, user- -friendly Human Machine Interface can further satisfy customer highly changeable site requirement, can be widely suitably used in different kind of industry areas.

Dongfang as a power system automation manufacturer with long time experience, having a lot of experience in product design, R&D, quality control, production, sales, and engineering services. DF5000 series medium voltage VFD makes use of Dongfang deep technical precipitation in electrical power control area, provides the VFD with more perfect, practical and reliable control functions and performance. Perfect design evaluation system and production and quality control system further guarantee high reliability of DF5000 series medium voltage VFD, allow the users to choose to use it with piece of mind.

EMC Characteristic

DF5000 medium voltage VFD have very strong EMC anti-disturbance characteristic, in testing performance by China electricity control & distribution equipment quality supervising & testing center, China VFD industry standard requirement is class II, but DF5000 take the initiative to do the testing for class IV which is most severe EMC testing, and smoothly passed through all tests in one time.
