Damper actuator for control of dampers in ventilation systems.
- Torque 5 Nm
- For dampers up to approximately 1 m2
- On/off control
- Spring return in the event of power failure
- Selectable direction of rotation
- Mechanical angle of rotation limiting
The spring return motors RDAB5S-24 and RDAB5S-24S are used to control small dampers to open or closed position in the event of power failure.
When connecting the supply voltage the actuator moves to the working position, at the same time the spring return tenses. If the power supply is interrupted, the energy stored in the spring moves the damper back to its safe position.
