Manufacturers and industrial motor users requiring a high-horsepower drive with a space-saving design can take advantage of the new Allen-Bradley PowerFlex 700L liquid-cooled drive from Rockwell Automation. Featuring the ability to withstand increasingly rugged environments, motor control users in a variety of industries will benefit from the drive’s high-performance, energy-efficient liquid-cooled technology. Unlike other liquid-cooled drives which require a water line to each Insulated Gate Bipolar Transistor (IGBT) power transistor to control the heat, the PowerFlex 700L features a single cooling input and output to the IGBTs. This proprietary liquid-cooled heatsink greatly increases power density resulting in a drive that is up to 65 percent smaller compared to similar horsepower air-cooled drives.
