History and present of EPRONA

The joint stock company Eprona is a traditional manufacturer of rectifying and charging equipment. The beginning of the production dates back to 1944 when a branch of Siemens, which was bombed out during the World War II, was moved to Rokytnice nad Jizerou. Both the production and R&D of selenium rectifying plates took place there simultaneously.

The company had more owners after the war, i.e. Krizik Co., Tesla, and ČKD. The production range remained the same though. Before the privatisation the company was a part of a national enterprise Elektropristroj Prague and a part of the ZSE Prague concern.

In 1990 the company was privatised at the first stage of the voucher privatisation. The General Assembly of new owners had changed its name to Eprona Ltd.

At present the Eprona brand stands for intelligent charging, supply as well as rectifying systems that feature the newest technologies, components and innovations. They are reflected in better performance parameters, better efficiency and a downward influence to a supply network as well as broader possibilities to a user. However, the systems are built with a maximum respect of the power and features / price rate at the same time.
