Air damper actuators
Rotary version, three-position control,
AC 24 V or AC 230 V
Electromotive rotary actuators for three-position control, nominal torque 20 Nm,
operating voltage AC 24 V or AC 230 V, for three-position control, span
mechanically adjustable between 0...90°, pre-wired with 0.9 m long connection
cables.
Type-specific variations with adjustable auxiliary switches for supplementary
functions and potentiometer for position indication.
To control air dampers in ventilating and air conditioning plants
• using a nominal torque of 20 Nm for damper surfaces up to 4 m
•
Ideal with modulating three-position controllers or ON/OFF-controls (e.g., outside air
dampers, flue gas dampers, etc.)
The actuator's rotational movement (clockwise or counterclockwise) depends on the
electrical control.
As soon as the operating voltage AC 24 V or AC 230 V is applied, the actuator starts to
turn.
The connected damper can be operated as follows via the respective actuator control:
•
Damper opens (0° ⇒ 90°)
•
Damper closes (90° ⇒ 0°)
• Damper remains in the current position
After uninterrupted runtime of approximately 200 s, the actuator turns off in the same
direction.
