The SINAMICS DC MASTER DC Converter range of DC converters sets itself apart as a scalable drive system - for basic as well as demanding drive applications. For the standard closed-loop control, the DC converter is equipped with a standard Control Unit for converters (standard CUD). Expanding the drive system using an additional Control Unit for converters (Advanced CUD) makes sense to address applications requiring a higher computational performance. The DC converters of the SINAMICS DC MASTER series combines open loop and closed-control and power units in one device and especially sets itself apart – above all - as a result of its compact, space-saving design. The Advanced Operator Panel AOP30 and the BOP20 operator panel are available for commissioning and on-site operation. 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 safety functions integrated in the device – known as "Functional Safety" – not only increase the safety level, but also make the device and the overall system more compact, cost effective, reliable and maintenance friendly. All this is achieved as one of the main contactors or circuit breakers required until now can be eliminated.

With the Functional Safety function integrated in SINAMICS DCM, for safety functions STO and SS1, now only one main contactor or circuit breaker is required to achieve SIL 3 (according to IEC 61508) and performance level PL e (according to EN ISO 13849-1) over the complete power range.
The training time and costs are reduced and the maximum number of identical components as a result of the extensive product range of SINAMICS DC MASTER. The seamless and integrated series of SINAMICS DC MASTER units encompasses a wide current and voltage range. The series of converters is designed to be connected to three-phase line supplies.
Flexible expandability regarding both functionality and performance. The comprehensive product range and the many options allow the DC converter to be optimally adapted to customer requirements - both technically and economically. Different customer requirements relating to the computational performance and peripherals (I/O) can be precisely fulfilled with the ability to select between either a Standard CUD, an Advanced CUD - or a combination of both.
The plant or system availability is increased by being able to quickly and simply exchange components. Components that can be exchanged have been designed so that they can be quickly and simply replaced. The spare parts that are available - assigned to the serial number of the drive unit - can always be viewed.
Simple commissioning and parameterization, menu-assisted at the AOP30 Advanced Operator Panel with graphics-capable LCD display and plain text display or PC-supported using the STARTER commissioning tool.
Simple integration into automation solutions, e.g. using the PROFIBUS communication interface provided as standard, PROFINET as an option together with various other analog and digital interfaces.
As a result of this Functional Safety function, a higher safety level is achieved with even lower engineering and integration costs. The device and the complete drive system are more compact and reliable – with lower capital investment and service costs.
