Belimo LMB24-10P-HM Non Fail-Safe Damper Actuator 45 in-lb 24V On/Off VAV Retrofit

The Belimo LMB24-10P-HM is a non fail-safe damper actuator designed specifically for retrofit applications in Variable Air Volume (VAV) systems. This 45 in-lb (5 Nm) actuator is engineered as a drop-in replacement for Belimo LM24-M and LM24-10P-M actuators used in OEM VAV controllers that have reached the end of their service life, requiring no alteration to the existing VAV system.

Key Features:

• 45 in-lb (5 Nm) torque output for reliable damper control
• AC/DC 24V dual voltage operation for flexible installation
• On/Off control with 95° angle of rotation
• Direct-coupled electronic design requires no crank arm or linkage
• Brushless Halomo motor technology for precise position control
• Electronic overload protection at all angles of rotation
• Visual position indicator for easy status verification
• Manual override with external push button on cover
• Low power consumption: 1.5W running, 0.2W holding
• Includes anti-rotation strap to prevent lateral movement

Installation and Operation:

The actuator mounts directly to damper shafts from 1/4" to 5/8" diameter using the included universal clamp (shafts up to 3/4" diameter can be accommodated with optional accessory clamp). The existing 5-pin Molex connector plugs directly into the replacement actuator, and 24 VAC/DC power is applied via a separate plenum-rated power cable. The actuator automatically stops when reaching end positions and provides electronic feedback to the VAV controller.

Specifications:

• Operating temperature range: -22°F to 122°F (-30°C to 50°C)
• Humidity range: 5 to 95% RH non-condensing
• NEMA 2 (IP54) protection rating
• cULus listed, CE approved
• UL94-5VA rated housing material
• Weight: 1.2 lbs (0.55 kg)

This actuator is ideal for building automation systems requiring reliable, maintenance-free damper control in HVAC applications. Backed by Belimo's 5-year warranty and ISO 9001 quality standards.
