7.2 kV, up to 120 MVA

The TMdrive-XL85 is a very high-power, medium voltage (7.2kV), AC fed drive

designed for high-efficiency and power-friendly operation in a broad range of

industrial applications. A single bank drive is rated for up to 30 MVA power level.

High reliability, low harmonic distortion, and high power factor operation are

designed into the drive.

TMEIC’s water cooled design and compatibility of piping materials with de-ionized

cooling system ensures that the drive has a MTBF of more than 20 years.
