› EME Controller, proven and reliable

Many years of experience in electrical machines and their control are a important requirement for the development of reliable control and monitoring electronics from EME. Functional, reliable and above all robust, EME controllers in synchronous generators and motors ensure stable operating parameters – regardless of the environment in which they are used. Thanks to extensive monitoring and protection functions, EME controllers meet even the highest demands.

  • Highest quality and reliability
  • Proven analogue or digital electronics for precise and stable voltage regulation
  • Safe operation through monitoring and protection functions
  • Analogue and digital interfaces
