Belimo LMB24-MFT-A02 Non Fail-Safe Damper Actuator 24V 45 in-lb MFT Programmable

The Belimo LMB24-MFT-A02 is a non fail-safe multifunction technology (MFT) damper actuator designed for proportional modulation of dampers in commercial HVAC systems. This direct-coupled actuator provides precise control for building automation systems without requiring spring return functionality.

Key Specifications:

• Torque: 45 in-lb (5 Nm) for reliable damper control
• Voltage: AC/DC 24V nominal (AC 19.2-28.8V / DC 21.6-28.8V range)
• Control: MFT programmable with 2-10 VDC default control signal
• Position Feedback: 2-10 VDC for accurate positioning confirmation
• Running Time: 150 seconds default (variable, programmable)
• Power Consumption: 2.5W in operation, 1.2W at rest
• Rotation: 95° maximum adjustable angle

Features:

• Brushless DC motor with Application Specific Integrated Circuit (ASIC) for intelligent control
• Digital rotation sensing (DRS) provides electronic overload protection throughout rotation
• Universal clamp accommodates damper shafts from 1/4" to 5/8" diameter (up to 3/4" with accessory clamp)
• Manual override with external push button release mechanism
• On-site programmable using Belimo PC-Tool software for custom configurations
• Compatible with add-on auxiliary switches and feedback potentiometers
• Anti-rotation strap included to prevent lateral movement
• NEMA 2 / IP54 rated plenum cable with 1/2" NPT conduit connector

Applications:

• Suitable for damper areas up to 11 square feet
• Ideal for non-spring return applications in building automation systems
• Designed for proportional control in typical commercial HVAC environments

The LMB24-MFT-A02 features reduced power consumption in holding mode and includes a reflective visual position indicator. Backed by Belimo's 5-year warranty and manufactured under ISO 9001 quality standards, this actuator delivers reliable, programmable damper control for modern HVAC applications.
