Our power business started with rectifiers in the communications market, and then it expanded into information equipment and industrial machinery.  Lately we have been entering the environmental and new energy markets as well, utilizing our compact and high conversion efficiency technology.
The information and communications markets increasingly use high-speed communication methods such as IP and optical networks.  This means increasing power consumption, demanding power supplies that can support diversified and power-saving supply systems.  We are developing power supplies of high efficiency and functionality and proposing optimal supply systems to address these needs.
Recently, in addition to existing energy conservation technology, new environmental concepts such as energy creation, storage and recovery are increasing in importance.  We are putting effort into developing power supplies that meet the needs of the times, including power supplies for LED lights, power conditioners for photovoltaic generators, power storage systems using lithium battery charge/discharge technology, etc.
With these product developments, we shall respond with precision to customer needs and contribute to the protection of the global environment.

We develop standard power modules that have high efficiency, low noise and high reliability and help build optimal supply systems.

48 V 12 V 3.3 V 24 V 5 V

These power supplies convert AC input and supply DC voltage for various loads.
The main products which we list are custom power supplies, but we also develop standard products.
