Even though the mains transformer in power supplies is often replaced by switching power supplies today, it is still a simple, low-interference solution for voltage adjustment. The mains transformer is reliable, does not cause EMC problems and has a good efficiency. We achieve this by using high-quality materials and components. The product spectrum ranges from single-phase transformers with or without rectification to three-phase transformers and stray field transformers.


  • Open or encapsulated design
  • End design with terminals, free ends or as a print transformer
  • optionally with temperature protection or temperature monitor


The applications of our grid transformers range from industrial electronics, traffic and environmental technology to medical technology. They are always used when standard solutions are not good enough for your application.
