Shut-off damper with electric motor – LM 24 A-F or LM 230 A-F
Consists of a DTU damper with a 24 or 230 V electric motor added.
The motor is controlled by a single-pole breaking contact. The motor has overload protection and stops automatically when the blade has reached its end stop. The stops can be continually adjusted. Although the current is connected, the motor is not damaged if blocked.
The spindle and motor can be disconnected from each other via a release button on the motor housing.
In outdoor installation, the motor should be protected from direct UV radiation.
The motor is installed at a distance from the damper, which makes it easy to insulate the ventilation duct.
Also the dampers DRU and DSU can be ordered with motor.
