Product Description P/N: GMX120-3
Description
The Belimo GMX120-3 is a heavy-duty, non-spring return damper actuator designed to regulate airflow within commercial building automation and HVAC systems. This 360 in-lb rotary actuator operates on a 100 to 240 VAC power supply, utilizing on/off and floating point control protocols to adjust damper positions accurately. By integrating advanced brushless DC motor technology, the unit provides consistent rotational torque output and minimizes mechanical wear during continuous climate control operations.

Information About GMX120-3
The GMX120-3 is a direct-coupled rotary actuator belonging to the robust GM series, constructed with a durable NEMA 2 rated housing to protect internal electrical components from dust and moisture exposure. It features an integrated universal mounting bracket that securely attaches directly to standard damper shafts, eliminating the need for complex external linkages or additional mounting hardware. System integrators utilize this component in large-scale air handling units, control dampers, and intake louvers where high torque and precise mechanical positioning are strictly necessary. The actuator incorporates electronic overload protection circuitry, allowing the motor to stall safely without sustaining internal damage when reaching the physical end limits of the damper stroke.
Key Features:
- High Torque Output: Generates 360 in-lb of rotational force to reliably manipulate large commercial control dampers under pressure.
- Brushless DC Motor: Reduces internal friction and mechanical fatigue while eliminating the need for periodic motor maintenance.
- Universal Power Compatibility: Operates efficiently across a wide alternating current voltage range of 100 to 240 VAC for seamless integration into existing electrical grids.
- Electronic Overload Protection: Automatically suspends motor operation at physical end-stops to prevent internal gear stripping and motor burnout.
- Manual Override Mechanism: Includes a localized push-button gear release that allows technicians to adjust the damper position manually without active electrical power.
- Direct-Coupled Mounting: Attaches straight to standard round or square damper shafts utilizing a single, standardized V-bolt clamp mechanism.
- On/Off and Floating Control: Supports versatile control signal configurations to match the specific automation logic of the building management network.
The GMX120-3 delivers the reliability and precision required for exact airflow calibration and heavy-duty damper manipulation in large-scale air handling networks.
