NRG-4Q Series DC Drive

The NRG-4Q Series from Minarik is a family of four-quadrant regenerative PWM DC motor drives. These DC motor controls provide bidirectional torque and speed control, allowing motors to run in both forward and reverse directions while regenerating energy back to the AC line during braking.

The series includes fractional and integral horsepower models with AC line inputs, characterized by their four-quadrant regenerative operation. Applications include paper handling, web tension control, and winding/unwinding systems where responsive bidirectional control is required.
