About SanRex

Over 80 years of creative engineering.

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.

Today, SanRex, is a company with an international presence, and whose name is synonymous with that of a preeminent supplier of highly engineered, reliable electronic solutions. Since its inception, Sansha has steadily grown into a company with about 1,000 employees worldwide, two manufacturing plants in Japan, one more in China and representative sales offices and service locations throughout Japan as well as in the US, Europe, China, Singapore, Korea and Taiwan. Our highly engineered products can be found around the world. The SanRex family of companies can truly meet your needs worldwide.
