SINAMICS DCM DC Converters – The universally applicable built-in unit

The scalable drive system for basic and demanding applications 

The power converter series SINAMICS DC MASTER convinces as a scalable drive system for both basic and demanding applications. For standard control, the DC power converter is equipped with a standard control unit for power converters (Standard CUD). For applications with a need for higher computing performance and a larger number of interfaces, the extension with an additional Control Unit for power converters (Advanced CUD) is ideal.
The DC power converter of the SINAMICS DC MASTER series combines control and regulation and power units in one device and is characterized above all by its compact, space-saving design. 

Technical data overview

Power range
6.3 kW up to 30 MW
Rated direct current
15 up to 3000 A
Rated supply voltage
3 AC 400 up to 950 V

SINAMICS DCM Control Module – For the modernization of existing plants

The scalable drive system for retrofit applications 

The SINAMICS DC MASTER Control Module offers the right solution for conversions and modernizations of existing DC drives. In contrast to the SINAMICS DC MASTER, which consists of control, regulation and power section, the module is primarily used if the power section of the existing systems is retained in the course of modernization. In direct current technology, there are many systems, which can no longer be connected to modern automation system, when they are in their current design. When retrofitting or upgrading these systems, the motor, mechanics and power section are left in the system and the control section is replaced by the control module. This provides an extremely cost-effective modern DC drive with the full range of functions of the proven full digitized devices in the SINAMICS DC MASTER series.
