The SINAMICS SM120 CM (Cabinet Modules) with its multi‑level Active Line Module is uniquely suitable for industrial power regeneration applications and ensures a superior performance while feeding energy into the grid. The SINAMICS SM120 CM is the best choice to fulfill the application specific requirements which range from the need to meet electric utility’s strict standards, to react fast in the event of line failures or to create an independent island network, since it provides line‑friendly and grid‑compliant behavior and enables island network and transformer‑less operations.
The Active Line Module of the SINAMICS SM120 Cabinet Module (CM) with its Modular Multilevel Converter (M2C) is ideal for applications such as:
