Belimo AMB24-SR Damper Actuator

Belimo AMB24-SR Damper Actuator is a versatile HVAC damper actuator designed for reliable, precise control. This device supports ON/OFF, direct-coupled, and proportional operation, making it suitable for a wide range of damper and HVAC system applications.

Powered by 24 Volt AC/DC supply, the AMB24-SR delivers a nominal 24 V with a running power of 2.5 W and 0.4 W in holding. It offers 180 in-lb torque and 95° rotation for precise damper positioning, while the 2–10 VDC output provides seamless control for modern HVAC controllers. The non-spring-return operation supports fail-safe design, and the rugged NEMA 2 / IP54 enclosure protects against dust and moisture in commercial environments.

Physical and connectivity specs help you plan installation: 3.46 in W x 2.49 in D x 7.47 in H; shaft diameter 1/2 to 1.05 in; supply connection is 3 ft of 18 AWG appliance cable with a 1/2 in conduit connector; operating temperature range -22 to 122 °F.
