Siemens SINAMICS G120C

The compact and versatile inverter with optimum functionality

The SINAMICS G120C is especially compact with a high power density, and offers a well-balanced combination of functions to address a wide range of applications. With its seven frame sizes, it covers a performance range of 0.55 kW to 132 kW.

The three new frame sizes FSD (22 kW to 45 kW), FSE (55 kW) and FSF (75 kW to 132 kW) are a real highlight. Thus, compact devices are now also available for higher performance ranges up to 132 kW for operation within three-phase grids. (Available in the 1st. half of 2017)


  • Compact even in high performance ranges up to 132 kW
  • Integrated DC-line reactor and EMC filter
  • Side by side installation of all frame sizes without current or performance reduction


  • Full integration of the drives in the TIA Portal system diagnostics
  • The use of the TIA Portal library concept ensures the easy reusability of the converters, including the parameter and hardware components


  • Intuitive series commissioning, cloning function through BOP-2, IOP or SD card
  • Simple and fast software parameterization
