AC Technology - AC Variable Speed Drives

Since its inception, AC Technology Corporation has had one mission – design and build AC variable speed drives that give the greatest value. AC Technology's commitment to quality, innovation, and value is a personal one, embraced by each of their employees.

The AC Tech recipe for success is simple, design products using common sense and imagination. The goal when developing new drive products is to increase usability while reducing cost; this requires that they constantly stay on top of the most recent advancements in solid state component technology and manufacturing techniques.

AC Tech has been a leader in furnishing drives which satisfy the needs of industrial facilities, OEM machines and commercial HVAC installations. They pioneered developments such as 575 VAC models, totally enclosed NEMA 4 drives, plain English programming, and the use of intelligent power modules (IPMs).

AC Technology's products consist of the most comprehensive line of VFD's in the world. The present product line offers the widest variety of voltages and enclosures within its fractional through 250 horsepower range. Drives are available with input voltages of 208, 230, 380, 460, and 575 VAC at 50 or 60 Hertz. Enclosure choices include open chassis, IP20, NEMA 1, NEMA 12, NEMA 4, and Stainless Steel NEMA 4X.
