About Sansha Electric
Sansha Electric Mfg. Co. Ltd., the parent company of SanRex, is located in Osaka, Japan, and is an innovative, dynamic leader in the power electronics industry. Since developing choking coil automatic transformers for movie projectors in 1933, we have been one of the pioneers in the industrial world as a manufacturer of power semiconductors and power supply equipment. In 1963, we started the manufacture of power thyristors and subsequently embarked on the development of power transistors, IGBT’s and other power semiconductor devices, keeping pace with developments in power electronics. We also applied these semiconductor devices to our industrial power supply equipment, which we provide to many industries.
