OVERVIEW
The Curtis 1228 MultiMode™ 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 a Curtis pro-
gramming device. Use of the programmer offers diagnostic and test capability
as well as configuration flexibility.
