Damper Actuator | 180 in-lb | Non-Spg Rtn | 24V | Modulating
For proportional modulation of dampers in HVAC systems. Actuator sizing should be done in accordance with the damper manufacturer’s specifications.
The actuator is mounted directly to a damper shaft up to 1.05” in diameter by means of its universal clamp, 1/2” self-centered default. A crank arm and several mounting brackets are available for applications where the actuator cannot be direct coupled to the damper shaft.
The actuator operates in response to a 2 to 10 VDC, or with the addition of a 500 W resistor, a 4 to 20 mA control input from an electronic controller or positioner. A 2 to 10 VDC feedback signal is provided for position indication or master-slave applications.
The actuator is not provided with and does not require any limit switches, but is electronically protected against overload. The anti-rotation strap supplied with the actuator will prevent lateral movement.
The AMB(X) series provides 95° of rotation and a visual indicator indicates position of the actuator. When reaching the damper or actuator end position, the actuator automatically stops. The gears can be manually disengaged with a button on the actuator cover.
The AMB(X)24-SR… actuators use a sensorless brushless DC motor, which is controlled by an Application Specific Integrated Circuit (ASIC). The ASIC monitors and controls the actuator’s rotation and provides a digital rotation sensing (DRS) function to prevent damage to the actuator in a stall condition. Power consumption is reduced in holding mode.
Add-on auxiliary switches or feedback potentiometers are easily fastened directly onto the actuator body for signaling and switching functions.

Modulation At Its Finest
Control and modulation are important in HVAC systems, and this damper actuator is my go-to device for autonomy over my system. It watches over your pipes like a hawk, looking for leaks, pressure spikes or drops, and if “you know what” hits the fan, you can manually override the system without the risk of being overloaded. The direct pressure indications helped me check for problems, and gave an idea of what the ideal temperatures should be. Modulating HVAC systems would not be easy for me if it weren't for this product.
Cost containment and safety
I have finally found the damper actuator that doesnt require any limit switches. The overload is not a frequent incident though it can be addressed by the actuator in case of emergency. These series can provide a solid 95 degrees rotation and the function ends when the actuator reaches the end position. Low voltage functioning provides better cost containment and safety for the users. Extra switching functions can be added to the current actuator to give you more possibilities to efficiently control your system.
Great controlling device
Belimo has tried to create the best damper actuator that you may possibly have installed to your heating system. It can connect to the CPU part as well as the thermostat and give you direct pressure indications from every single part of your pipelines system. The actuator is directly mounted on the damper shaft. A crank arm and several other brackets are available when there is no chance to adjust it directly to the damper shaft. Overall, a great controlling device for any heating or cooling system.
