Operating Mode: The actuator moves the damper to the operating position while tensioning the return spring. When the supply voltage is interrupted, the damper returns to the safety position using spring energy.
Simple Direct Mounting: Easy mounting on the damper shaft with a universal shaft clamp and anti-rotation device.
Adjustable Angle of Rotation: Mechanically adjustable with end stops.
High Functional Reliability: Overload protection, no limit switches required, and automatic stop at the end stop.
