Belimo AFBUP-S Damper Actuator

The Belimo AFBUP-S Damper Actuator is a reliable ON/OFF, direct-coupled actuator designed for HVAC control. Its spring-return operation ensures fast damper reset for efficient system balancing and energy savings.

It supports both AC and DC control, with a wide voltage range of 24-240 VAC or 24-125 VDC, and 50/60 Hz compatibility, making it versatile across different installations.

With 7 W running power and 3.5 W holding, it delivers 180 in-lbs of torque across a 95-degree rotation, suitable for most dampers in commercial HVAC systems.

Constructed for durability, the unit features a NEMA 2 / IP54 enclosure, a zinc-coated metal body with a plastic casing, and a shaft compatible with 1/2 to 1.05 inch diameters. The supply cable is 3 ft of 18 AWG with a 1/2 inch conduit connector. Includes 5 mm hex crank and two SPDT auxiliary switches for enhanced control.

Approved for UL (Canada and US), UL 60730, CE, CAN/CSA E60730, and ISO 9001, this actuator meets essential safety and quality standards for HVAC applications.
