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: Directly mountable on the damper shaft with a universal shaft clamp and an anti-rotation device to prevent actuator rotation.
Adjustable Angle of Rotation: Features mechanical end stops for adjustable angle of rotation.
High Functional Reliability: Overload protected, requires no limit switches, and automatically stops at the end stop.
Flexible Signalling: Equipped with an adjustable auxiliary switch (0...100%).
