SINAMICS SM120 CM

A premium and customizable drive system featuring interchangeable modules to offer the most efficient drive design tailored to your complex application’s requirements.

sinamics sm120 cabinet modules

SINAMICS SM120 CM medium voltage drives are designed for applications with special or complex requirements. All of the harmonized modules and functions in a SINAMICS SM120 CM allow for the realization of numerous product specific solutions tailored to your applications needs. All of our line modules (DC Bus, M2C, and DFE) and our motor side modules (3L NPC and M2C) have been selected due to the proven advantages found in our current portfolio.


The converter SINAMICS SM120 CM integrates  our Multi-cell-converter (M2C) technology either as line module, motor module or both.
The M2C topology consists of several low-voltage cells. Switched in series, they generate an output voltage at medium-voltage level.
