Modular system design

The individual SIRIUS Innovations components are modules from the complete SIRIUS
modular system (up to size S12, 250 kW at 400 V), which are matched to one another in
terms of their size and their technical data. This enables individual requirements to be met
quickly and cost-effectively. And it goes without saying that this applies to the uniform range
of accessories as well.
