SRA81 Spring reset damper actuator

Utilizes an imported DC motor/brushless motor to deliver torques of 5NM, ensuring robust performance and durability. Designed for building ventilation fields, it facilitates mechanical reset upon power failure and electric start, capable of enduring more than 30,000 cycles of repeated action.
Key Specifications:
• Core Function: Electric damper actuation with spring reset mechanism for reliable power-off operation
• Motor Technology: Imported DC/brushless motor providing 5NM torque for effective damper control
• Control Precision: High-precision control system for accurate execution and positioning
• Operating Range: Adjustable full stroke up to Max 95°, with mechanical limit setting
• Noise Levels: Motor running at 46dB, spring reset at 62dB, ensuring quiet operation
• Compatibility:
Suitable for dampers under normal wind resistance, with 1NM matching 0.1 square meter
Rotating direction manually adjustable
IP54-rated for protection against dust and water ingress
Operating temperature range: -20°C to +50°C; storage temperature range: -30°C to +80°C
Typical Applications:
✔ Building ventilation systems requiring reliable damper control
✔ HVAC systems needing power-fail safe actuation
✔ Industrial processes demanding precise and repeatable damper actions
✔ Environments with stringent noise requirements, benefiting from low-noise operation
✔ Applications needing high durability and longevity, supported by over 30,000 cycles of operation
