Aurora Datasheet

The Aurora is a compact, economical DC motor speed control designed for OEM applications in HVAC, electronic and industrial control markets. Aurora regulates DC motor speed from a control signal (0-5 VDC, 0-10 VDC, 0-20mA) or potentiometer. Voltage to the motor is varied using a buck control circuit that operates at a high frequency to achieve maximum power efficiency at minimum size.  Typical DC motor controller applications include: industrial machinery, conveyors, process equipment, fans and centrifugal pumps. 100% testing in an ISO 9001:2008 manufacturing facility ensures a robust, quality product for your DC motor control requirements.

Benefits of using Aurora DC motor controller include acoustical noise reduction, environmental (humidity, temperature or pressure) regulation, greater product reliability, improved safety and energy savings.
