Belimo TFRB24-3 Actuator
The Belimo TFRB24-3 is a spring return damper actuator designed for reliable on/off or floating point control in HVAC systems. Delivering 22 in-lb of torque, this direct-coupled actuator is engineered for small dampers and air terminal units where fail-safe operation is required. It operates on a universal 24VAC/DC power supply, drawing only 2W during runtime and 1.3W in the holding position, ensuring energy-efficient performance in demanding applications. The brushless DC motor provides consistent torque and precise control without the maintenance concerns associated with traditional brushed motors. Its compact chassis allows for easy installation in tight mechanical spaces, while the manual override feature assists in commissioning and system testing. Designed for a 95-degree rotation, the TFRB24-3 ensures positive shut-off and fail-safe positioning upon power loss, protecting critical system components and maintaining airflow control in VAV systems and air handling units.
- Fail-Safe Reliability: Mechanical spring return ensures the damper returns to the safety position during a power interruption.
- Universal Power Input: Compatible with both 24VAC and 24Vdc circuits for versatile field integration.
- Quiet Operation: Precision gearing and brushless motor design minimize acoustic impact in noise-sensitive environments.
- Compact Profile: Ideal for retrofit projects and tight plenum spaces where standard actuators cannot fit.
- Dual Control Logic: Supports both 3-point floating and on/off signals to match specific BAS controller requirements.
Common Questions
What is the typical runtime for the TFRB24-3?
This actuator features a motor runtime of 95 seconds and a spring return time of less than 25 seconds at ambient temperature.
Can the direction of the spring return be changed?
Yes, the fail-safe direction (clockwise or counter-clockwise) is determined by the orientation of the actuator mounting on the damper shaft.
Is this model compatible with floating point controllers?
Yes, the Belimo TFRB24-3 is specifically designed to handle floating point signals as well as standard on/off control.
