Frequently asked questions

What if I need more space in the control cabinet?

The SINAMICS DCP (DC Power Converter) product series contains all components of a DC-DC converter in one compact device. It’s ready for immediate use without additional engineering. Easily implement a power extension by connecting several SINAMICS DCPs in parallel.

As a buck and boost converter, the SINAMICS DCP can connect two DC voltage systems at different voltage levels for easy energy exchange. This requires fewer components and saves installation space.

Siemens offers the SINAMICS DCP 250kW, a device that can realize output voltages of up to 1200V and is the optimal foundation for designing and implementing test stands for electric vehicles, aligned with increasing automotive industry requirements.

Are these DC-DC converters sustainable?

The SINAMICS DCP technology significantly reduces peak energy loads, saving up to 70% in diesel consumption. In automotive test stands, the SINAMICS DCP acts as a buck and boost converter, optimizing power supply to vehicle inverters in electric drive unit test systems.

For industries aiming to boost energy efficiency, integrating energy storage is key. That is why SINAMICS DCP offers a transformative solution that meets the demands of modern industries striving for more sustainable and energy-efficient practices.

How do these DC-DC converters work with other SIMAMICS solutions?

A Motor Module from the SINAMICS S120 multi-axis system is the core component of the SINAMICS S120 DC-DC Converter. By adding supplementary components, it becomes a complete DC-DC converter that can be individually adapted to the application. This modular approach allows easy integration into the SINAMICS S120 drive line-up mechanically, electrically, and in terms of software. It also generates synergy effects such as a uniform look and feel, use of existing communication interfaces, and a universal design.
