Belimo AFBUP-S 24-240V Spring Return Damper Actuator 180 in-lb Torque with Auxiliary Switch

The Belimo AFBUP-S is a universal multi-voltage spring return actuator designed for on/off control of HVAC dampers. This versatile actuator accepts a wide voltage range of 24-240V AC/DC, making it suitable for various building automation systems without the need for voltage-specific models.

Key Features:

• 180 in-lb (20 Nm) torque rating for reliable operation of large dampers
• Spring return mechanism ensures fail-safe positioning during power loss
• Multi-voltage capability: 24-240V AC/DC for maximum flexibility
• Integrated auxiliary switch for feedback and status indication
• On/off (2-position) control for simple open/close applications
• Durable construction for long-lasting performance in commercial HVAC systems
• Direct mounting to damper shafts with standard Belimo hardware

This actuator is ideal for HVAC applications requiring fail-safe spring return operation, including fire and smoke dampers, outside air dampers, and other critical damper control applications. The auxiliary switch provides valuable feedback for building automation systems, enabling monitoring of actuator position and system status.
