Hitachi Retired A/C Drives
Hitachi released a number of new series in recent years which made figuring out which series replaced what a bit confusing.

Hitachi was founded in 1910 and their first product was Japan's first 5-horsepower electric induction motor. They became Japan's leader in electric motors.

Hitachi is now a global company that offers a wide range of consumer and business products. The division we are an authorized distributor for is the Industrial Components and Equipment division of Hitachi American, Ltd. which includes their low voltage AC drives/industrial inverters.

Hitachi first exported to the U.S. in 1926 and Hitachi America, Ltd. was established in 1959 with the first manufacturing facility opening here in 1977. Hitachi America, Ltd. Is located in Tarrytown, New York.
