It operates on 24 VAC or 24 VDC power supply and accepts an analog control signal for precise proportional positioning. With a compact, direct-coupled design, this actuator mounts directly to damper shafts without the need for crank arms or linkage in most applications. The NEMA 2 and IP54 enclosure ratings provide protection against dripping water and dust, making it suitable for a range of mechanical room and air handling unit environments. HVAC technicians and mechanical contractors install this unit as part of VAV, mixed-air, and economizer control sequences.\u003c\/p\u003e\u003cp\u003eThe LMX24-SR-T is suited for use in commercial HVAC systems where modulating damper control is required. Typical applications include outside air, return air, and exhaust air dampers in air handling units, rooftop units, and built-up systems. Its analog input allows integration with DDC building automation systems and standalone controllers that output a modulating signal. Because this is a non-spring return actuator, the damper position is held by motor torque rather than a return spring, which is appropriate for applications where fail-in-place behavior is acceptable.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e45 in-lb rated torque for direct-coupled damper control\u003c\/li\u003e\n\u003cli\u003eNon-spring return design holds position on power loss\u003c\/li\u003e\n\u003cli\u003eAccepts analog control signal for modulating proportional positioning\u003c\/li\u003e\n\u003cli\u003eOperates on 24 VAC or 24 VDC power supply\u003c\/li\u003e\n\u003cli\u003eNEMA 2 and IP54 enclosure rating for moisture and dust resistance\u003c\/li\u003e\n\u003cli\u003eLow 3 VA power draw minimizes transformer loading\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation actuator for HVAC damper assemblies requiring a 45 in-lb non-spring return modulating actuator with a 24-volt supply.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician or mechanical contractor familiar with low-voltage control wiring and damper actuator mounting procedures. Disconnect and lock out all power to the air handling unit and control panel before beginning installation or wiring. The actuator should be mounted directly to the damper shaft per the manufacturer mounting instructions, ensuring the shaft clamp is fully secured before restoring power. Verify control signal wiring and supply voltage against the building automation system output specifications before commissioning.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTorque\u003c\/strong\u003e: 45 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: 3 VA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eControl Signal\u003c\/strong\u003e: Analog (Modulating)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Return\u003c\/strong\u003e: Non-Spring Return\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnclosure Rating\u003c\/strong\u003e: NEMA 2, IP54\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: LMX24-SR-T\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BELIMO","offers":[{"title":"Default Title","offer_id":51284097368370,"sku":"LMX24-SR-T","price":239.78,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309279124.jpg?v=1781068523","url":"https:\/\/voomisupply.com\/products\/belimo-lmx24-sr-t-damper-actuator-45-in-lb-24v-modulating","provider":"Voomi Supply","version":"1.0","type":"link"}
