Operating Mode: The actuator connects with a standard control signal of 0...10 V and drives to the position defined by the control signal. Measuring voltage U serves for the electrical display of the damper position 0...100% and as control signal for other actuators.
Simple Direct Mounting: Direct mounting on the damper shaft with a universal shaft clamp, equipped with an anti-rotation device to prevent rotation.
Manual Override: Possible with push-button (gear train disengaged while pressed or locked).
Adjustable Angle of Rotation: Mechanical end stops allow for adjustable angle.
High Functional Reliability: Overload protection with no need for limit switches, automatically stops when end stop is reached.
