The MGC Series (photo) is a new microprocessor-based, fully regenerative SCR (silicon-controlled rectifier) control. An onboard microprocessor allows the MCG to be preconfigured for a user’s specific application. Furthermore, users can select various modes of operation out of the box, including torque, linear torque, independent speed/torque, cycling via limit switches, cycling via feedback, and positioning. The MGC eliminates the need for additional items, such as relays, switches and PLCs, thereby reducing setup and installation time. A new current-limiting algorithm prevents overshoot, extending brush life and reducing demagnetization, which extends motor life. The controller is rated for a maximum current of 11 A and a maximum temperature of 50°C. — American Control Electronics (ACE), South Beloit, Ill.
