Belimo CMB24-3-T 24V Floating Actuator 18 in-lb Non-Spring Return

The Belimo CMB24-3-T is a compact electric actuator designed for precise control of HVAC dampers and valves in commercial building automation systems. This non-spring return actuator operates on 24VAC/DC power and features floating control logic for two-position or modulating applications.

Key Specifications:

• Torque Output: 18 in-lb (2 Nm) for reliable damper positioning
• Power Supply: 24 VAC/DC universal voltage
• Control Type: ON/OFF floating point control
• Return Type: Non-spring return (holds position on power loss)
• Wiring: Screw terminal connections for easy installation
• Rotation Time: Approximately 90 seconds for 90° rotation
• Operating Temperature Range: -22°F to 122°F (-30°C to 50°C)

Features & Benefits:

• Compact design fits in tight mechanical spaces
• Robust construction for long service life in demanding applications
• Low power consumption for energy efficiency
• Manual override capability for testing and maintenance
• Position indication for visual verification
• Suitable for damper control in VAV systems, fan coil units, and air handling units

The CMB series actuators are ideal for controlling butterfly dampers, louver dampers, and zone control applications where precise positioning and reliable operation are essential. The non-spring return design maintains damper position during power outages, making it suitable for applications where fail-in-place operation is required.
