By connecting the Sinamics S120 Active Line Modules (ALM) in parallel, the operator can now use the Booksize format continuously up to a rated power of 228kW. The parallel connection of the 55kW ALM also enables a higher peak power for high dynamic machines than a single 120kW ALM. The space-saving internal busbar can be used by suitable arrangement of the dc link components. 55, 80 and 120 kilowatts (kW) of ALM can be connected in two parallel circuits. This feature is supported by the new firmware version V5.2.
