TMEIC TMdrive-XL80 Medium Voltage AC Drives

3.8 kV, up to 30 MVA

The TMdrive-XL80 is a medium voltage (3.8kV), AC fed drive designed

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

industrial applications.

High reliability, low line-side 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.
