Motor Controller for CURTIS 1228 Series Description: – For Curtis 1228 motor controller is a permanent magnet motor speed controller designed for use in mobility aid scooters and other small electric vehicles, such as sweeper/scrubbers. It offers smooth, silent, cost effective control of motor speed and torque. A four quadrant, full bridge power output stage provides for solid state motor reversing and full braking power without additional relays or contactors. The 1228 controller is fully programmable by means of the handheld programmer for Curtis 1313. Use of the programmer offers diagnostic and test capability as well as configuration flexibility.
