The EDA-8000 Electric Damper Actuator provides
clockwise and counterclockwise incremental control of
dampers and mounts directly on the damper drive
shaft, eliminating the need for costly and complicated
linkage combinations.
The mechanically limited torque output of 100 in·lb
provides long actuator life, protection of the controlled
equipment, and minimal setup and calibration time.
The EDA-8000 Electric Damper Actuator operates on
24 VAC power.
