The MD60 Reliance drive line is manufactured by Rockwell Automation and replaces the obsolete drive lines discontinued in 2009. These drives are easy to install and use, including all necessary components within the drive itself. These AC Drives range from 1/4HP (0.25HP) to 5HP and have an optional installation kit that can accompany them for NEMA 1 / IP30. The MD60 includes a built-in LED display as well as operator controls, including a single turn potentiometer for speed reference. Built-in dynamic braking circuitry only requires the addition of a braking resistor to meet higher performance application needs to handle fast accel & decel rates.
