Download PDFThe Siemens GMA126.1E damper actuator is ideal for applications where a secure closure of air handling dampers is required in the event of a power failure. Thanks to the integrated return spring, the actuator automatically moves the damper to the fail-safe position, ensuring maximum system safety. The actuator is designed for on/off control and powered by AC 24 V.
The return spring automatically closes the damper in the event of a power failure
The actuator is designed for two-point control with AC 24 V power supply
Possibility of mechanically limiting the rotation angle from 0...90°
Robust construction and long lifespan for HVAC applications
The GMA126.1E is equipped with a robust mechanism with a nominal torque of 7 Nm, ensuring reliable and long-term function even with frequent cycles. The adjustable mechanical rotation range of 0...90° allows precise adaptation to specific applications. The actuator is suitable for dampers up to approximately 1.5 m² in size (depending on friction) and also allows tandem mounting to increase torque.
