The entrepreneur Josef Heinzinger founded the company in 1959 to manufacture precision power units. The earliest customers included established Munich companies such as "Rhode & Schwarz" and "Siemens" as well as many universities and research institutions.

Soon the company moved to Rosenheim. In that surroundings the Heinzinger developers found the appropriate environment for the realisation of customer-specific requirements. The company quickly became known as a manufacturer of high-voltage and high-current power units and developed its reputation amongst the growing research institutions and the developing universities and technical colleges.

Especially due to the excellent reputation in research circles was Heinzinger able to significantly expand his customer base in the following years. Research institutions around the world could be counted then, as well as today, to the users.

In 1992 Josef Heinzinger accepted the offer from Knürr AG to take over Heinzinger electronic and to incorporate the company into the Knürr group as "Specialist for electronics in mechanics". In the course of the following ten years the Rosenheim location developed into the competence centre for power supply and power distribution solutions for the Knürr group. In addition to the "classical" Heinzinger precision power units for high-voltage and -current, the uninterrupted power supply systems and battery back-up solutions for the telecommunication market were developed and produced. Additionally the company had the responsibility within the Knürr group for all power distribution systems and data & network technology. Heinzinger made use of this time to further improve the reputation of the products especially with industrial companies and to be present around the globe via Knürr's world-encompassing sales force.

The 2002 restructuring of the Knürr group made it possible for the former manager Alfred Werndl to continue leading the Heinzinger electronic GmbH in the course of a management buy out. Since then the company has been concentrating again with all its energy on its core competence of high-voltage and high-current, with precision power units and comprehensive services around these product worlds.

Today Heinzinger electronic GmbH is an independent, owner-managed company that is quite successful in its market. The Heinzinger brand is a registered trademark and vouches for precisely the virtues of developing and manufacturing technically sophisticated solutions and highly precise DC power units of cutting-edge technology. Precisely as discerning customers have always appreciated it around the world.
