  • System integration - from components to complete system.

Tradition and innovation in one

For around a quarter of a century, we have focussed on the development of technology that is energy-efficient and therefore causes less harm to the environment - an extremely creative activity that requires a flair for experimentation with and investigation of new technologies.

It can be taken for granted that we know what we are doing. Our engineers are specialists in areas such as power electronics, open-loop and closed-loop control systems, microcontrollers and DSP technology as well as data communication, sensor systems and SW engineering.

"Design for Manufacturing" and "Design for Testability" are not just empty words for us; they have a definite practical meaning. Our know-how and our excellent network of relationships with other external experts are warranties for quality and outstanding solutions. We are also, of course, highly skilled in the application of modern industrial methods of manufacture.

In this respect, we rely on - among others - Lenze, our parent company, which operates production facilities that are available to us all over the world. We possess comprehensive expertise in all the necessary design-to-market processes - from the first idea to a product that is ready to be produced in series. All these stages, of course, have been certified in accordance with the process model of ISO 9001.
