High Performance DC Power Supplies
Since the end of the 1970s, JEMA has been strongly involved in the study, development and production of high performance power supplies for particle accelerators. In this field of application, each product is developed individually. These power supplies are often one-off items or are produced in very small series.
Modular High Performance DC Power Supplies
Without compromising performance, today the rationalization of infrastructure and energy expenditure has become a major issue. From this perspective, JEMA has developed the MOSAIC modular high performance power supply system...
