Product features
Mode of operation
The actuator moves the damper to the operating position at the same time as tensioning the
return spring. The damper is turned back to the safety position by spring force if the supply
voltage is interrupted.
Simple direct mounting
Simple direct mounting on the damper spindle with a universal spindle clamp, supplied with an
anti-rotation strap to prevent the actuator from rotating.
Manual override
Manual operation of the damper with the hand crank, locking in any position with the interlocking
switch. Unlocking is manual or automatic by applying the operating voltage.
Adjustable angle of rotation
Adjustable angle of rotation with mechanical end stop.
High operational reliability
The actuator is overload-proof, requires no limit switches and automatically stops when the end
stop is reached.
Notes
• Connect via safety isolation transformer.
• Parallel connection of other actuators possible.
