High frequency switching and ultra low voltage drops provide very high efficiency and silent operation. Costs, heatsinking requirements and motor and battery losses are reduced. Low end torque, range and battery life are increased. Օ Environmental protection provided by a rugged anodized aluminum extrusion housing. Simple mounting and wiring with push-on type connectors for control signals. Plated solid copper busses used for all power connections. Thermal protection and compensation circuit provides constant current limit over operating range and under temperature and over temperature cutback. No sudden loss of power under any thermal conditions. Օ No adjustments are required. Simple installation ՗ Uses a two wire throttle potentiometer. Potentiometer fault protection circuitry disables controller if throttle wires become open. Օ High pedal disable prevents controller operation if key is turned on while throttle is applied. > Plug braking diode internal to controller.
