ASF 113S: Damper actuator with spring return and positioner

Product catalog summary

Overview: The ASF 113S is a damper actuator with spring return and positioner designed to improve energy efficiency through overload protection and end stop detection. It is suitable for various applications including air dampers, shut-off dampers, butterfly valves, and multi-leaf dampers.

Features:

Compatible with controllers having a continuous output (0...10 V).
Self-centring spindle adapter and manual adjustment with hexagon socket.
Maintenance-free and suitable for all fitting positions.

Technical Data:

Power Supply: 24 V~ ±20%, 50...60 Hz or 24...48 V= ±20%.
Power Consumption: 3.5 W, 5.0 VA.
Running Time: 90° motor - 90 s, 90° spring - 15 s.
Torque: 7 Nm with a maximum angle of rotation of 95°.
Control Signal: 0...10 V, with positional feedback signal 0...10 V.
Ambient Conditions: Temperature range from –32 to 55 °C, humidity < 95% rh.

Construction:

Weight: 1.3 kg.
Housing: Cast aluminium.
Protection: IP 54 (suspended), IP 42 (not suspended).

Standards and Directives: Complies with IP protection, low-voltage directive 2006/95/EC, and EMC directive 2004/108/EC.

Operation: The positioner controls the motor based on the controller's output signal. The actuator moves to the 90° position and returns to 0° when power is cut off. The direction of rotation is determined by the actuator's mounting.

Engineering and Fitting Notes: Multiple dampers can operate in parallel, but actuators must not be mechanically connected. The angle of rotation can be limited in 5° increments.

Safety Warning: Opening the housing poses a risk of injury due to the return spring.

Outdoor Installation: Devices should be protected from weather when installed outdoors.

Disposal: Follow local laws for disposal. More information is available in the product's material and environment declaration.

ASF 113S: Damper actuator with spring return and positioner-2

Product data sheet Description of operation The built-in positioner controls the positioning motor depending on the controller’s output signal y. When the positioning signal is increasing, the coupling piece turns to the 90° position (scale on actuator) until the power-dependent cut-off. In the two end positions (limit stop of damper or limit stop due to angle-of-rotation limit, max. angle of rotation of 95° reached) or in the case of an overload, the torque-dependent cut-off is activated (no limit switches). If the power is cut off or is switched off by a safety device at connection 2 (cable...
