Belimo TFRB120 Actuator
The Belimo TFRB120 is a specialized spring return actuator designed for reliable on/off control in HVAC systems. Delivering 22 in-lb of torque, this fire and smoke damper actuator ensures fail-safe positioning during power interruptions, making it a critical component for life safety applications. Engineered for versatility, it features a universal power supply that accepts 100 to 240 VAC, simplifying field installations across various line voltage requirements. The compact NEMA 2 housing allows for installation in tight mechanical spaces while maintaining robust performance. This spring return damper motor is commonly utilized in small-to-medium dampers and regional air handling units where precise mechanical operation is non-negotiable. By utilizing a brushless DC motor controlled by an ASIC, the TFRB120 provides consistent run times and overload protection without the need for limit switches, preventing motor burnout and ensuring long-term operational integrity in demanding commercial environments.
Key Benefits for Technicians:- Mechanical Fail-Safe: Reliable spring return functionality ensures dampers return to their safety position upon power loss.
- Broad Compatibility: The 100 to 240 VAC input range eliminates the need for external transformers in many retrofit scenarios.
- Simplified Mounting: Direct-coupled design with a universal shaft clamp facilitates fast installation on various shaft diameters.
- High Efficiency: Low power consumption during holding cycles reduces overall building energy load.
- Durable Construction: Built to meet UL60730 requirements, providing proven performance in professional HVACR applications.
Can the Belimo TFRB120 be used for modulating control?
No, this model is designed strictly for 2-wire on/off control. For modulating applications, a 2-10VDC or 4-20mA compatible model should be selected.
Does this actuator require a specific mounting orientation?
The TFRB120 is designed for multi-position mounting; however, it should be installed in an environment consistent with its NEMA 2 rating to protect against moisture and debris.
What is the typical run time for the spring return?
Under standard load conditions, the spring return timing is typically less than 25 seconds, ensuring rapid closure for safety sequences.
