Overview of the energy management process

We offer you a unique portfolio for efficient energy management in the industry – a process that is used to optimize the energy requirements. We divide operational energy management into the three phases: identification, evaluation and implementation, and support you with suitable hardware and software solutions in each phase of the process.

The innovative products of the SIRIUS industrial controls portfolio can also make a major contribution to a plant's energy efficiency (see http://www.siemens.com/sirius/energysaving).

The soft starters make the following contribution to the energy efficiency of the plant as a whole:

• Energy management
  Provision of energy data such as current, voltage and power (3RW44) via bus to higher-level systems
• Current management
  Avoidance of current peaks, thus reducing the load on the grid and the mechanical system
• Reduction of control cabinet temperature rises
  Depending on technology, lower intrinsic power loss than speed-controlled drive systems, and therefore less cooling required, making a more compact design possible. All sizes are equipped with bypass protection, resulting in lower power losses after start-up

Product advantages

• Soft starting and smooth ramp-down (soft starting only available for 3RW30)
• Stepless starting
• Reduction of current peaks
• Avoidance of mains voltage fluctuations during starting
• Reduced load on the power supply network
• Reduction of the mechanical load in the operating mechanism
• Considerable space savings and reduced wiring compared with conventional starters
• Maintenance-free switching
• Very easy handling
• Seamless compatibility with the SIRIUS modular system
