Spring Return Damper Actuator 24VAC/DC MPN:LF24-SR
Introducing the Spring Return Damper Actuator 24VAC/DC from Belimo - designed for fail safe, modulating damper control in HVAC systems. This innovative actuator provides true spring return operation for reliable fail-safe application and positive close-off on air tight dampers. With up to 95 of rotation and a graduated position indicator displaying 0 to 95, this model offers consistent torque to the damper with or without power applied to the actuator. Its brushless DC motor controlled by an Application Specific Integrated Circuit (ASIC) and microprocessor ensures efficient operation, while the microprocessor device provides data to the ASIC for accurate positioning. The actuator's fail-safe position is determined by a microprocessor, which monitors the rotation rate of the DC motor. This powerful HVAC solution is suitable for a wide range of applications in the heating, ventilation, and air conditioning (HVAC) industry, making it an essential tool for maintaining optimal indoor environments.
Top product features:
- True Spring Return Operation Ensures consistent torque to the damper with and without power applied to the actuator for reliable fail-safe application.
- Up to 95 Rotation Provides precise control over damper positions for optimal performance in HVAC systems.
- Graduated Position Indicator Allows easy monitoring of damper position for accurate positioning and improved diagnostics.
Top product applications:
- HVAC Systems Designed for fail safe, modulating damper control in heating, ventilation and air conditioning (HVAC) systems, providing precise control over damper positions and reliable fail-safe applications.
- Air Tight Dampers Positive close-off on air tight dampers ensures a seal that prevents unwanted air leakage, saving energy and maintaining optimal indoor environment conditions.
- Commercial Spaces Used in commercial spaces such as office buildings, schools, hospitals, or hotels to maintain consistent temperature and humidity levels for occupant comfort and safety.
