Operating on 24 VAC or 24 VDC power at 2 VA, it accepts two-position and floating point control signals, making it compatible with standard on\/off and tri-state zone controllers. The unit carries an NEMA 2 and IP54 enclosure rating, providing protection against light moisture and dust ingress in typical mechanical room and air handling environments. Licensed HVAC technicians and controls specialists are the primary installers of this component.\u003c\/p\u003e\n\u003cp\u003eThe LUB24-3 is suited for damper control applications in variable air volume systems, zone control setups, and air handling units where non-spring return actuation is appropriate. Its floating point control capability allows incremental positioning via open and close pulse signals from a building automation system or standalone zone controller. This actuator is appropriate for both new construction and retrofit installations where direct-coupled damper actuation is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e27 in-lb torque output for reliable damper shaft engagement\u003c\/li\u003e\n  \u003cli\u003eAccepts 24 VAC or 24 VDC power supply at 2 VA draw\u003c\/li\u003e\n  \u003cli\u003eTwo-position and floating point control signal compatibility\u003c\/li\u003e\n  \u003cli\u003eNon-spring return design holds last position on power loss\u003c\/li\u003e\n  \u003cli\u003eNEMA 2 and IP54 enclosure rating for light moisture and dust protection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style direct-coupled replacement damper actuator for HVAC systems requiring 24V non-spring return actuation with on\/off or floating point control.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or controls specialist familiar with low-voltage wiring practices and applicable mechanical codes. Disconnect and lock out all power to the air handling system before mounting or wiring the actuator. The actuator mounts directly to the damper shaft without additional linkage in most applications; verify shaft size compatibility before installation. Follow all local codes and manufacturer wiring diagrams when connecting control signal and power supply terminals.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTorque\u003c\/strong\u003e: 27 in-lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePower Supply\u003c\/strong\u003e: 24 VAC \/ 24 VDC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSupply VA\u003c\/strong\u003e: 2 VA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eControl Signal\u003c\/strong\u003e: Two Position, Floating Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnclosure Rating\u003c\/strong\u003e: NEMA 2, IP54\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpring Return\u003c\/strong\u003e: Non-Spring Return\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: BELIMO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: LUB24-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BELIMO","offers":[{"title":"Default Title","offer_id":51284123779378,"sku":"LUB24-3","price":171.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309279086.jpg?v=1781069117","url":"https:\/\/voomisupply.com\/products\/belimo-lub24-3-damper-actuator-27-in-lb-24v-on-off","provider":"Voomi Supply","version":"1.0","type":"link"}
