6.0/6.6 kV, up to 92 MVA

The TMdrive-XL75 is a high-power, medium voltage, AC fed drive designed for high-efficiency and power-friendly operation in a broad range of industrial applications. A single bank drive has 15/20/23 MVA power level, and multiple banks can be used to obtain higher power levels. Conservative design uses 4500 V, 2100 A IEGTs, and the power bridges are water cooled.

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.
