Belimo AHQB24-MFT-100 Actuator

The Belimo AHQB24-MFT-100 is a high-performance linear damper actuator engineered for precise control in demanding commercial HVAC systems. This non-spring return actuator delivers a consistent 44 lbf (200 N) of actuating force, making it an ideal choice for modulating air dampers up to 12 sq. ft. Equipped with Belimo’s Multi-Function Technology (MFT), this unit supports a wide range of control signals, including 2-10 VDC, 4-20 mA (with a 500 Ohm resistor), PWM (1500 Ohm), and floating point or on/off configurations. Its brushless DC motor is managed by an ASIC for digital rotation sensing, ensuring overload protection throughout the entire 4-inch (100 mm) stroke. With a quick running time of 7 seconds, it provides near-instantaneous response for critical airflow adjustments. The NEMA 2 rated housing and plenum-rated cable allow for versatile installation in ceiling spaces and air handling units.

• Programmable Versatility: Standard 2-10 VDC input can be field-reconfigured for PWM, floating point, or 4-20 mA using the Belimo PC-Tool or ZTH handheld device.
• Efficient Performance: The brushless DC motor significantly reduces power consumption to 1.5W in holding mode while maintaining a constant 7-second runtime.
• Simplified Installation: Features a manual override button for gear disengagement and mechanical end stops to adjust stroke increments by 0.8 inches.
• Direct Integration: Use as a proportional control actuator for AHUs, VAV terminals, and louvers without the need for complex linkages.

• How do I change the control signal from 2-10V to 4-20mA? Use a 500 Ohm resistor (ZG-R01) to convert the 4-20 mA signal into a 2-10 V control signal for immediate compatibility.
• Can this actuator be used in return air plenums? Yes, the AHQB24-MFT-100 is UL 2043 listed, making it suitable for use in air plenums per NEC requirements.
• Is manual override available during power loss? This is a non-spring return model. It features an external push button for manual gear disengagement to position the damper during setup or maintenance.
