EMC Engineering

Electronic devices have to run properly, be secure and safe from interferences. They should neither influence other devices during the operation nor cause inadmissible circuit feedback. To be able to ensure this in the research and development processes, Deutronic has an in-house EMC test laboratory (electromagnetic compatibility). The laboratory with its consulting and proposed solutions is used together with local partners.
