Product Description P/N: AMB24-3
Description
The Belimo AMB24-3 is a non-spring-return rotary damper actuator for on/off and floating-point control in commercial HVAC systems. Powered by 24 VAC/VDC, it delivers 180 in-lb of torque and completes 90° of travel in 95 seconds. Its direct-coupled mounting and adjustable rotation range support airflow regulation in ventilation and air handling equipment.

Information About AMB24-3
The AMB24-3 is part of Belimo’s AMB Series of electric damper actuators for applications requiring powered positioning without automatic spring return. A sensorless brushless DC motor and electronic rotation monitoring protect the drive against overload throughout its operating travel. Its universal clamp mounts directly onto compatible damper shafts up to 1.05 inches in diameter, while accessory brackets accommodate installations requiring linkage. A manual gear-release button, direction-selection switch, and mechanical position indicator assist with installation and adjustment.
Key Features:
- High Torque Output: Provides 180 in-lb for dampers selected according to the damper manufacturer’s torque requirements.
- Dual Control Modes: Supports on/off operation and floating-point, three-point positioning.
- AC/DC Power Compatibility: Operates from either 24 VAC or 24 VDC supplies.
- Direct Shaft Mounting: Uses a universal clamp for compatible damper shafts up to 1.05 inches in diameter.
- Selectable Rotation Direction: Includes a 0/1 switch to match actuator movement to the installation.
- Adjustable Angular Travel: Provides up to 95° of rotation with a mechanical end stop.
- Consistent Running Time: Maintains 95-second travel per 90° within its rated operating load.
- Manual Gear Release: Allows manual damper positioning through an external push button.
- Electronic Overload Protection: Monitors actuator rotation and protects the drive during stalled conditions.
- Visual Position Indication: Provides a mechanical indicator for checking damper position locally.
- Reduced Holding Consumption: Uses 0.5 W while maintaining position.
The AMB24-3 delivers the reliability and precision required for on/off and floating-point airflow control in commercial HVAC installations.
