SIEB & MEYER offers a regenerative power supply unit for SD2 multi-axis devices

Using energy intelligently – instead of wasting it: With the new regenerative power supply unit for the SD2 multi-axis devices, SIEB & MEYER takes another step towards sustainability. In processes, where brake energy was formerly lost in the form of waste heat, it is now fed back to the company's power grid. As a result, the energy consumption decreases and the processes become more climate-friendly.

 

"In cooperation with a partner, SIEB & MEYER offers regenerative power supply units. Thanks to this option, users of our SD2 multi-axis devices can achieve an even higher efficiency level," explained Markus Finselberger, head of sales drive technology at SIEB & MEYER. “Rather than discharging excess energy from the process as waste heat, we return it to the grid and make use of it. This saves resources, lowers the CO₂ foot print and, in the long term, reduces operating costs.”

The SD2 multi-axis devices by SIEB & MEYER have always offered the advantage that one power supply unit can supply several SD2 devices using a common intermediate circuit, from which the energy is distributed to the drives as required. When a motor is decelerated, the produced energy flows to the intermediate circuit to be used directly for the acceleration of another motor. Until now, however, there was a limit: if more brake energy was generated than required by the system, the excess energy had to be converted to heat via brake resistors.
 

Double benefit for users

With the new regenerative power supply unit, this problem is a thing of the past. Excess energy is now fed back to the grid. This has several advantages for the user:

  • Lower energy consumption: the whole system works more efficiently since energy is no longer lost unused.
  • Lower operating costs: Companies save electricity costs since the energy fed into the grid can be used further.
  • Climate-friendly production: Less energy wasted means less CO₂ emitted – a real benefit for the environment.

 

"Our customers benefit twice over," summarized Markus Finselberger. "Their application becomes not only more sustainable but also more economical. An intelligent solution that pays off."
