Belimo TF24 US Damper Actuator, 18IN-LB, 24VAC/DC, 2.5W, 50/60Hz

Belimo TF24 US Damper Actuator, 18IN-LB, 24VAC/DC, 2.5W, 50/60Hz

The Belimo TF24-US is a compact and efficient non-spring return (NSR) damper actuator, engineered for precise and reliable control of HVAC dampers in commercial building automation systems. With its universal 24V AC/DC power input and a torque of 18 inch-pounds (2 Nm), this actuator is the ideal solution for modulating control of VAV terminals, air handlers, and other low-torque damper applications.

Designed for direct mounting onto Belimo damper linkages, the TF24-US simplifies installation and reduces maintenance needs. Its robust construction and silent operation ensure long-term, trouble-free performance, making it a trusted choice for HVAC professionals worldwide.

Key Features & Benefits:

• 18 in-lb (2 Nm) Torque: Provides ample rotational force for small to medium-sized dampers, ensuring smooth and accurate damper modulation for optimal airflow control.

• Universal 24V AC/DC Power: Offers exceptional flexibility for integration into both AC and DC control systems (50/60 Hz), simplifying procurement and inventory.

• Non-Spring Return (Floating) Control: The TF24-US is a modulating actuator that drives the damper to a commanded position and holds it without the need for a spring to return to a failsafe position. Ideal for standard control sequences.

• Low Power Consumption (2.5W): Energy-efficient operation reduces overall system energy costs and is compatible with low-capacity control transformers.

• Compact & Lightweight Design: Saves space in tight mechanical units and plenums, and is easy to handle during installation.

• Direct Mounting: Specifically designed for easy, direct attachment to Belimo damper linkages, reducing installation time and hardware requirements.

• Manual Override: Features a built-in manual override knob, allowing for testing, balancing, and manual control during setup or power loss.

• Long Service Life: Built with high-quality materials and brushless DC motor technology for exceptional durability and millions of duty cycles.
