Belimo AFBUP-S-X1 Universal Voltage Damper Actuator with Manual Override

The Belimo AFBUP-S-X1 is a spring-return damper actuator designed for HVAC damper control applications. Operating across a wide universal voltage range of 24V to 240V AC/DC, this actuator offers exceptional installation flexibility, eliminating the need to match actuator voltage to a specific control circuit.

Equipped with a manual override handle, technicians can manually position the damper blade during commissioning, testing, or power-off maintenance without the need for auxiliary tools. The spring-return mechanism ensures the damper returns to its fail-safe position upon loss of power, making it suitable for safety-critical ventilation and smoke control applications.

Key Features:

• Universal voltage input: 24V–240V AC/DC — no voltage matching required
• Spring-return fail-safe operation for reliable damper positioning on power loss
• Manual override handle for hands-on damper positioning during service
• On/Off or floating point control signal
• Compact, direct-coupled design — no crank arm or linkage required
• Plenum-rated housing suitable for air handling unit and duct installations
• Visual position indicator for easy status confirmation
• UL and CE listed for compliance with North American and European standards

The AFBUP-S-X1 is part of Belimo's AF-series actuator family, engineered for longevity and low maintenance in commercial and industrial HVAC systems. Its universal voltage design and integrated manual handle make it a go-to choice for contractors and building automation professionals seeking a versatile, reliable damper drive.
