The L-Series Position Controller provides a building block approach to total engine management. The microprocessor-based, bi-directional actuator design easily attaches to fuel pumps, mixers, or throttle bodies. The L-Series Position Controller accepts a position command and drives the 0-60 degree output shaft to the commanded position based on an internal shaft position sensor. The high-efficiency torque motor delivers 0.34 N•m (0.25 lb-ft) nominally over 60 degree travel range to operate fuel or air control devices.
