The Sirius 3RW5 range (photo) is a new generation of soft starters for simple to demanding drive requirements. This comprehensive range of devices for the soft starting of three-phase asynchronous motors from 5.5 to 1,200 kW enables efficient and future-proof machine concepts to be implemented easily and cost-effectively, says the manufacturer. The new Sirius 3RW5 soft starters are suitable for any drive, they can be easily integrated into the automation system, and they supply data directly to MindSphere, this company’s cloud-based, open IoT operating system. Practice-related functions (such as automatic parameterization with changing startup characteristics) and integrated properties (such as electrical ruggedness in the case of fluctuating line voltages) support smooth operation in a host of applications. — Siemens AG, Munich, Germany
