The ASF 122 and ASF 123 motorised damper drives with spring return are used to operate air dampers, frost dampers and smoke dampers. The maximum angle of rotation of the damper drives is 90°. In the event of a power failure or whenever a safety facility is triggered, the motor releases the gears, so that the spring can move the damper back to the starting position. The maximum torque and holding torque of the ASF 122 and ASF 123 damper drives is 18 Nm in each case. The drives are activated by controllers with a switched output (2- or 3-point control). The damper drive is overload-proof. On reaching the damper or motor end positions, an electronic, torque-dependent facility ensures that the motor is switched off. Manual adjustment and spring winding are done using the Allen key supplied. Power supply is either 24 V(AC), 24...48 V(DC) or 230 V(AC).
