Description
The input phase-shifting transformer feeds a set of series-connected low-voltage power modules, and at the output multilevel PWM builds a voltage close to a sine wave. This design gives an input THDi < 5 % without a separate harmonic filter, so the drive does not overload the plant grid. The efficiency together with the transformer is ≥ 96 %. The motor receives a voltage with little distortion, which reduces winding heating and the stress on the insulation. The XMV670 is installed in an electrical room, while the XMV660 Outdoor is an outdoor version and is mounted directly next to the pump or compressor station.
How to choose
The first parameter is the grid voltage the input is rated for, from 2.3 to 13.8 kV. Next the installation location is determined. The XMV670 is taken for an electrical room, and the XMV660 Outdoor for an open site. Low-voltage motors are served by SD750 converters up to 2200 kW, and if speed control is not needed, a VS70 soft starter for 50–500 A is enough.

FAQ
What grid voltage are the XMV drives rated for?
The input accepts from 2.3 to 13.8 kV, so the drive is connected to the plant MV grids without an additional step-down transformer.
What level of harmonics does the XMV670 produce?
The input THDi is below 5 % thanks to the phase-shifting transformer and the multilevel design.
How does the XMV660 Outdoor differ from the XMV670?
The difference is in the version. The XMV670 is intended for indoor installation, and the XMV660 Outdoor for outdoor mounting next to process equipment.
What is the efficiency of the XMV medium-voltage frequency converter?
At least 96 % including the input transformer, so its losses do not need to be added to the calculation separately.
For which machines are the XMV670 / XMV660 Outdoor used?
For pumps, compressors and fans, where speed control instead of throttling reduces energy consumption.
