A premium medium voltage converter for low and high speed applications with single or multi motor systems that require high dynamic performance and regenerative capabilities.

sinamics sm150

After decades with our SIMOVERT ML & SIMOVERT ML2 converters, transrapid line feeder systems and traction power supply links it has all culminated into the SINAMICS SM150. The SINAMICS SM150 is a high-end drive converter for low and high speed applications with single or multimotor system configurations that might require high dynamic performance and regenerative capabilities. Available in drive configurations featuring either IGBT and IGCT technology for a wider power range of medium voltage applications.

Your Benefits

  • Easy plant integration due to the compact design and highly flexible configuration

  • Simple operator control with the user-friendly operator panel

  • Smooth and reliable operation due to the integrated maintenance functions: the converter signals automatically and well in advance when maintenance is required and / or components need to be exchanged

  • High ruggedness and reliability thanks to the use of IGCT / HV-IGBT technology and fuseless design, combined with intelligent response to external disturbances

  • Hassle-free integration into higher-level automation systems due to PROFIBUS interface supplied as standard and analog and digital interfaces

  • High degree of service-friendliness due to the innovative power section design, e.g. compact phase modules and excellent accessibility of all components only applicable to the IGCT technology.

  • Ideal for direct energy exchange on the common DC bus in applications with motoring and generating drives
