The Woodward L-Series Position Controller is a microprocessor-based bi-directional actuator that provides a building-block approach to total engine management. It accepts PWM, 0–5 V, or CAN position commands and drives a 0–60 degree output shaft with a high-efficiency torque motor. Available in multiple mounting configurations including integration with fuel pumps, throttle bodies, and mixers.
