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.

The thing they say about the overload protection is absolutely true. Would have to spend another plenty if not for this feature after a recent power surge we had. Absolutely must-have.
A perfect fit
My HVAC system benefits greatly from this actuator. Free shipping offer is great, thanks!
Cool wireless control
This damper actuator from Belimo can be easily monitored and controlled wireless. It is the most lightweight and minimal in size device you would ever have for your heating system. There is no need to have a dedicated electric line to give it power and you will be amazed by the rotating head of the valve. The actuator has a direct connection to the thermostat, and you can stay reassured that any possible malfunction or system overload would instantly trigger the alarms.
