Siemens Answers with SINAMICS DC Master – the Next Generation of DC Drives

The SINAMICS DC Master combines the advantages of its predecessor, the SIMOREG DC Master, with those of the SINAMICS drives family. Many of the same tools and components so successful in AC technology are now made available for SINAMICS DC drives. This series of drives sets itself apart as a scalable drive system – both for basic as well as demanding and sophisticated applications. For the standard closed-loop control, the DC converter is equipped with a standard control unit for converters (standard CUD). For applications demanding a higher computational performance and interfaces, the system can be expanded by an advanced CUD.

The SINAMICS DC Master series combines the open-loop and closed-loop control and power units in one device and SINAMICS-DCMtherefore offer a compact, space-saving design. The AOP30 Advanced Operator Panel and the BOP20 Basic Operator Panel are available for commissioning and local operator control. The interfaces of the CUD and the number of digital inputs and outputs can be supplemented using additional modules – such as the TM15 and TM31 Terminal Modules.

The SINAMICS DC MASTER is the new generation of DC converters from Siemens.
The name SINAMICS DC MASTER – briefly: SINAMICS DCM – stands for the strengths of this new generation. It combines the advantages of its predecessor – the SIMOREG DC-MASTER – with the advantages of the SINAMICS family.
Available in two different unit versions, SINAMICS DC MASTER can be optimally integrated into each plant or system:

  • SINAMICS DCM DC Converter, the chassis unit that can be universally used
  • SINAMICS DCM Control Module, to modernize existing plants and systems, especially for very high power ratings
