The Belimo AFB24-SR Damper Actuator is a direct-coupled, modulating damper actuator designed for HVAC systems. Its spring-return operation delivers reliable fail-safe positioning, ensuring precise air control across varied environmental conditions.
Powered by 24 V AC/DC at 50/60 Hz, it delivers 180 in-lb of torque through a 95° rotation. The output is a 2–10 V DC control signal at 0.5 mA, ideal for precise damper positioning. Its zinc-coated metal body with a plastic casing provides robust protection (NEMA 2, IP54) for challenging installations. Running power is 5.5 W; holding power is 3 W, and it accommodates shaft diameters from 1/2 in to 1.05 in for flexible mounting.
