This document provides installation, troubleshooting, and maintenance information for the Curtis 1268-5403 SepEx Controller, designed for generic golf cart applications.
The Curtis 1268-5403 is a remanufactured SepEx (Separately Excited) motor controller for 36V/48V battery pack systems. It manages the motor's armature and field windings to control vehicle speed and direction. The controller integrates various optional features such as walkaway protection, brake light relay control, mode switching, LED driver, and backup alarm output. It interfaces with a throttle potentiometer (0-5K or 0-5V), a speed sensor, and a programmer for diagnostics and configuration. The controller is equipped with an internal pre-charge resistor, eliminating the need for an external one on the solenoid.
