Description
The Siemens GDE131.1U is a reliable, non-spring return electric damper actuator designed for precise control of HVAC dampers in commercial and light industrial applications. Built for durability and consistent performance, this actuator delivers 44 lb-in (5 Nm) of torque and operates on 24 Vac with floating (3-position) control, making it ideal for zoning, air handling units, and ventilation systems.
With a 90-second run time at 60 Hz, the GDE131.1U ensures smooth and accurate damper positioning. Its compact design, low power consumption, and IP54-rated enclosure make it suitable for a wide range of indoor HVAC environments.
Features:
- Reliable 44 lb-in Torque Output – Provides consistent power for accurate damper positioning in HVAC systems.
- 24 Vac Floating Control (3-Position) – Compatible with standard HVAC control systems for open/close/hold operation.
- Non-Spring Return Design – Maintains position without spring return, ideal for controlled airflow applications.
- Fast, Precise Operation – 90-second run time at 60 Hz (108 seconds at 50 Hz) for smooth modulation.
- Low Power Consumption – Efficient operation at just 2.3 VA reduces energy usage.
- Compact, Durable Construction – Space-saving design with IP54 protection for dependable performance in demanding environments.
- Wide Operating Range – Supports 20.4–28.8 Vac and operates in up to 95% relative humidity.
