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

Popular Products Series


SINAMICS G130 chassis units have been designed for variable-speed drives in machine building and plant construction.
They have been specially tuned to the requirements of drives with quadratic or constant load characteristics with medium performance requirements without regenerative feedback.

Mitsubishi F740 Series Frequency Inverter

The FR-F700 Series was launched in 2004 as the successor to the FR-F500 Series VFD. With growing market demands for energy saving inverters in building automation, water processing and HVAC industries, the FR-F700 was able to exceed power-saving expectations in fan and pump applications by incorporating “OEC” (optimum excitation control) which combined maximum drive utilization with minimal power consumption.


We provide the assembled version of 6RM80 product, and all the accessories are from the official Siemens, which are 100% tested and strictly tested before delivery.

ACS800-104/-104LC – inverter module

ACS800-04 – single drive modules

The single drive modules variant ACS800-04M offers more possibilities. Including normal bookshelf mounting and flat (sideways) mounting. This improves installation into cabinets with a shallow inner depth. Frame size R7 also offers a variant with motor connections available from the bottom of the module. Giving you the possibility of a narrower cabinet for relevant installations.
