The Friend of DC Links

On this picture you can see three of our dynamic storage managers.In the center of the system is the Dynamic Storage-Manager DSM 4.0. It is the connection between the electric storage units and the DC-grid, which in Drive Controllers are called DC-Links. The DSM 4.0 is always being connected directly to the DC-Link of the drive controller. No matter which task the DCLink will bring, the Dynamic Storage-Manager will fulfill it. And it will do it fast. So fast, that humans and machines wouldn´t even notice if the DSM 4.0 would not communicate with the drive controller or the higher-level control.

It charges with regen energy from the system and supplies it once needed or once being told to do so. Just so that it is best for the application. Or for the mains, where unwanted effects of high power loads can be leveled and avoided. Consistently used, this can save a lot of costs.

Hereby it supports the drives electronics, especially in short cycles, in a way that the service life of the drives electronics is drastically extended and unplanned standstills are minimized. This support can even have the effect that the system can be accelerated if the mechanical parts of the system are made for faster cycles. Faster machines, higher quantities, higher productivity and more profit!


Especially when being used with batteries, the DSM 4.0 shows its strength as an absolutely uninterruptable power supply for DC-grids, and with it for drive controllers and thus electric drives. Voltage dips as well as planned or unplanned mains interruptions lose their threat. And if a 24 voltage Emergency Energy Supply NEV is added to the system, even the device, that are in need of a 24 voltage Installation dimensions and grid, such as controls, industry-PCs, sensors, brakes and many more stay active.
