Power output stages for the plasma generation

The powerplas output stages are able to generate up to 20 kw output power. Always enough energy in combination with  snychronized treatment systems.

The power units  are equipped with a new control regulation and exterm rapid semi conducter technology.  

The powerplas output stages are used for the plasma generation within the expertplas- I, X and S series as well as within the expertjet systems:


As an alterantive we also offer the powerplas output stages as a single component  to marketing partners.

High voltage transformers for plasma applications

The expertplas high-voltage transformers are matched to the expertplas power output stages in order to provide the necessary power conversion for generating the plasma or corona discharge at the electrodes.

Due to their compact design, they can be easily integrated. 

Depending on the power requirements, the transformers are equipped with air- or oil cooling.

The expertplas high-voltage transformers are used for plasma generation in the expertplas I, X and S series as well as in the expertjet systems:


Alternatively, we offer the transformers as single components for system suppliers, or develop the transformers according to customer specifications.
