With its new Sinamics S120 Chassis-2 and Sinamics S120 Cabinet Modules-2, Siemens is addressing changing requirements in the field of high-performance drives over recent years. Not only do users nowadays expect simplified engineering, installation and integration into their own in-house solutions, they also expect to pay lower operating costs. At the same time, the requirements imposed on frequency converters are growing in step with complex new applications. With its innovated Sinamics S120 Chassis-2 devices, Siemens is offering its customers new features and functions designed to provide extreme flexibility and efficiency. The high-performance converters are also designed to enable optimum adjustment to different sectors of industry and all kinds of application.
A particularly impressive feature of the new power modules is their compact size. By making some optimizing touches to the design, Siemens has succeeded in reducing the footprint of the new devices by between 30 and 60 percent – depending on the model – compared to the familiar Sinamics S120 devices, providing improved performance with a standardized design over the complete range.
Sinamics S120 Chassis-2 or Cabinet Modules-2 are compatible with the familiar Sinamics and Masterdrives series, guaranteeing simple integration and retrofitting into existing plants. Their improved cooling concept makes for greater availability, while helping to minimize the cost of cooling and prevent unwanted damage. The use of standardized terminals makes for simplified installation and more rapid diagnosis.
Whether users opt for Sinamics S120 Chassis-2 or Cabinet Modules-2, either design can be dimensioned for a precise fit no matter how challenging the application. The standard pulse frequency has been increased to 2.5 kilohertz to provide significantly increased system efficiency and minimized derating. Their high-performance IGBTs and reliable capacitors, robust electronic modules, innovative cooling concept and variable-speed fans as well as type and system testing make Sinamics S120 Chassis-2 and Sinamics S120 Cabinet Modules-2 exceptionally durable while reducing upkeep, downtime and maintenance costs.
The new cabinet system Sinamics S120 Cabinet Modules-2 combines all the innovative benefits of the chassis version for increased flexibility and maximum reliability alongside simplified engineering and improved economy.
