The Belimo LMB24-3-P10-T is a high-torque rotary actuator designed for the precise control of dampers in specialized HVAC systems. Engineered for On/Off and floating point control, this 24V damper actuator delivers a consistent 45 in-lb torque rating, ensuring reliable operation for medium-sized air handling units and zone control dampers. The non-spring return design incorporates a brushless DC motor technology, providing accurate positioning and long-term performance stability without the maintenance overhead of traditional motors. Contractors utilize this direct-mount actuator for its versatile compatibility with 24VAC or 24VDC power supplies and its integrated 10-foot plenum-rated cable, which simplifies Field wiring and speeds up installation in cramped plenums or mechanical rooms. This model features a manual override button and 0 to 95-degree angle of rotation, making it a standard choice for VAV systems and custom HVAC zone control applications where industrial-grade reliability is non-negotiable.

Key Benefits

• 45 in-lb Torque Output: Provides ample power for dampers up to approximately 11 square feet.
• Multi-Voltage Compatibility: Operates efficiently on both 24VAC and 24VDC power sources for site flexibility.
• Floating Point Control: Allows for incremental positioning in complex air distribution sequences.
• Plenum-Rated Cable: Includes a 10-foot P10-T cable for direct connection without additional conduit in most jurisdictions.
• Simple Installation: Tool-free manual override and universal shaft clamp accommodate standard damper spindles.

Common Questions

How do I wire the Belimo LMB24-3-P10-T for floating point control?
This actuator uses a 3-wire configuration. Terminal 1 is common, Terminal 2 is the 24V supply for clockwise rotation, and Terminal 3 is the 24V supply for counter-clockwise rotation.

Can this actuator be used on round dampers?
Yes, the universal clamp is designed to secure onto both round and square damper shafts, typically ranging from 1/4 inch to 5/8 inch.

What happens if the actuator reaches its end of stroke?
The Belimo LMB24-3-P10-T features electronic stall protection; it automatically stops at the end of its rotation without the need for mechanical limit switches, preventing motor burnout.
