Programmable Controller: Motor controller is designed to provide smooth, quiet, and efficient motor speed and torsion control. The addition of the ability to be programmed via the 1313-4331 handheld programmer or the 1314 Pc programming station. In addition to configuration flexibility, the use of the programmer provides diagnostic and testing capabilities. Rugged Construction: The controller uses rugged anodized aluminum extruded shell that meets IP65 environmental sealing standards for use in harsh environments. Ideal solution for a variety of electric vehicle applications including industrial trucks, personnel carriers, material handling vehicles, golf carts and more. High Efficiency: High frequency switching and ultra low voltage drop enable high efficiency and quiet operation. Simple installation and wiring is achieved using push in connectors for control signals and plated solid copper buses for power connections. Wide Compatibility: Compatible with two wire potentiometers or voltage throttles. Throttle failsafe circuitry disables the controller if the throttle cable is open. If the key is turned on while the throttle is in use, the high pedal disable feature prevents the controller from operating. Safe to Use: Insert the brake diode inside the controller. Thermal protection and compensation circuits provide constant current limiting during the operating range as well as during under temperature, and over temperature cuts; there is no sudden power loss under any thermal conditions. Undervoltage cutout protects against low battery voltage, including low voltage caused by external loads.
