Sanyo Denki
Sanyo Denki is a Japanese manufacturer of precision cooling equipment, power systems, and motion control products. The company develops and sells industrial fans, power supplies, servo motors, and thermal management solutions for information technology, telecommunications, factory automation, and medical industries. Headquartered in Tokyo, the company competes internationally with manufacturers in the electronics and automation sectors.
History
Founded in 1927, Sanyo Denki emerged during Japan's interwar industrial expansion alongside firms such as Mitsubishi Electric, Toshiba, Hitachi, NEC, and Fujitsu. In the postwar period the company expanded product lines amid the economic growth that involved conglomerates like Mitsui and Mitsubishi Heavy Industries. During the 1960s and 1970s Sanyo Denki responded to the rise of semiconductor manufacturing and minicomputer systems used by companies such as IBM, Digital Equipment Corporation, UNIVAC, and Honeywell. In the 1980s and 1990s the firm shifted toward high-reliability cooling and motion control for clients in the emerging networks and data center markets including Cisco Systems, Sun Microsystems, and Nortel. Globalization in the 2000s saw the company establish overseas facilities to serve markets alongside competitors like Delta Electronics, Nidec, Emerson Electric, and Schneider Electric. Throughout its history Sanyo Denki has navigated technological shifts influenced by standards from organizations such as JEITA, IEC, and ISO.
