Damper Actuator | 180 in-lb | Non-Spg Rtn | 24V | On/Off/Floating Point



For on/off and floating point control 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, 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 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 AM... 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 AM...24-3… 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.

The AM...24-3-S version is provided with 1 built-in auxiliary switch. This SPDT switch is provided for safety interfacing or signaling, for example, for fan start-up. The switching function is adjustable 0 to 95°. The auxiliary switch is double insulated so an electrical ground connection is not necessary.

Add-on auxiliary switches or feedback potentiometers are easily fastened directly onto the actuator body for signaling and switching functions.

Energy efficient

I got a deal on free shipping which is amazing. It also comes with a 5-year warranty from Belimo which is a testament of quality work. The actuator used for our ventilation unit works like a charm and is very reliable. The device is very energy efficient.

Effective and reliable

We use the AMB24-3 on our air conditioning units. They have a 5 year warranty and I got free shipping which saves some bucks. Built to last and priced right.

Best for my ventilation and air conditioning systems

Ive heard about the AMB24-3 Damper Actuator since I needed to buy new stuff for my ventilation and air conditioning systems. When my friends heard about my upgrade needs, they recommended this one since it works so well. It has a brush-less DC motor that is connected to an integrated circuit. This is so that the device can be safely interacted within the maximum rotation of around 95 degrees. The device is also insulated properly so theres no issue with grounding or what. If thats not enough, the AMB24-3 has a five-year warranty and free shipping by Belimo should you push with this one as well. Totally worth it.

Thats a great choice

This AMB24-3 Damper Actuator made by Belimo is such a great device to buy for my electrical and high ventilation needs. It provides up to 95 degrees of rotation, and contains an anti-rotation strap to prevent any loose movement around. Its power consumption is greatly reduced even with a sensor-less, brush-less DC motor. In turn, the motor is controlled by a circuit which ensures that everything that passes through the system gets monitored. The device is also electronically and doubly insulated. Ultimately, this product is worth buying due to its durability and performance to keep my ventilation system as fixed as possible.
