Test drive a SINAMICS G120C

Siemens Try Before You Buy program allows you to test drive SINAMICS G120C drives - to install one or more in your applications before you commit to purchasing.

This program is designed to give you the opportunity to prove to yourself (and your management!) that a SINAMICS variable speed drive will not only get the thumbs-up for performance, energy savings, etc,. but also for decreasing installation and commissioning time.

Typical Applications

  • Machine building

  • Mixers

  • Conveyors

  • Fans

  • Pumps

  • Compressors

  • Basic production machines
