Jovyatlas History

On  December 1st 1945  JOVYATLAS was founded by the engineer Dr. Richard Klaus Jovy. The history of JOVYATLAS is marked by continuity, pioneering spirit and innovative strength. Electronic rectifiers for cinemas, frequency converters, alternating rectifiers and later Systems and hospital emergency power supplies equipment were part of the first product range programme of Dr. Jovy. We still comply with this tradition today.


Our product range is constantly being adapted to modern requirements, with a view to the future. In its over 70-year history JOVYATLAS has developed into the international company it is today – selling on all five continents.
