When to choose MV-VFD instead of LV-VFD?

Why Pick LV [<690v] Drive & Motor Why pick MV [>690v] Drive & Motor over LV

LV drives are lower cost / HP than MV

Reduces some safety & MV training concerns

HP range is small enough Individual preference

Lower cost wiring, smaller cables Lower power system harmonic

impact High HP LV require dual winding

motors Individual preference

Trend: Some users select MV at >250 HP, Many users select MV over 500 H

For 6.6 KV and Motor power above 500hp; Other than an extra step-down input transformer and step-

up output Transformer, LV Drives needs an extra output sine filter to reduce the THD (Total Harmonic

distortion). So overall maintenance cost will also increase.

Why to choose Wanlida MV-VFD?

Wanlida Series MV Drives offers integrated Transformer, Integrated by-pass cabinet and 48 pulse at

lowest possible cost compared to other drives manufacturers which generally offer only 12/18/24/36

pulse in market.

Wanlida MV VFD employs IGBT power units in series, obtaining MV by means of overlap wave, so it

has perfect output performance without harmonics, at the same time, Wanlida MV VFD adopts

advanced IGBT, rectifier bridge, PLC and electrolytic capacitor etc main components from Germany,

which ensure advanced technology and reliability.

The power cell has bypass function, at the same time, the power cell and control system have a very

good protective design to dust, ferrum pulveratum, acid mist, moisture etc.

The bypass cabinet of Wanlida MV VFD has a function of "five-protection", meanwhile, it has a

pressure relief channel, so it can rival the Medium voltage switchgear.
