Siemens has adapted the electrical and mechanical design of the Sinamics S120 Chassis-2 to meet today’s and tomorrow’s market requirements. The new frequency converters are designed to meet the very highest demands with state-of-the-art components, an innovated cooling concept with speed controlled fan and is always type and system tested to ensure the very highest reliability and availability.
Added to these benefits, the derating is minimized, for example more than halved at low output frequencies. Overall the electrical design was adapted to allow simple engineering with minimal derating while increasing the life time even under worst case conditions. Supported with additional function, such as condition monitoring, to ensure longest possible operation time with the ability to plan maintenance based on the real requirement of the application.
The devices themselves are both lighter and smaller, and compatible to all their predecessors. Largely due to the improved electrical properties and the new mechanical design, the new Sinamics S120 Chassis-2 devices can be simply integrated into existing plants. The DataMatrix code provided on the type plate allows technical data and certificates to be accessed at any time – directly opening up the possibilities of Industrie 4.0 for the user. The converters are particularly suited for dynamic applications that benefit from the combined DC-Link to improve the energy efficiency in the process, like steel mills, paper mills, cranes, conveyors, test rigs, and many more.
