The unit ships with a 24-volt, two-position motor actuator that is powered in both directions — powered open and powered closed — eliminating reliance on spring return. The motor uses a 3-wire hookup consisting of a common, a power-open leg, and a power-closed leg. Built-in LED position indicators display red when the blade is fully closed and green when the blade is fully open, confirming full-travel completion before illuminating. Licensed HVAC technicians and sheet metal mechanics are the primary installers of this type of damper in residential and light-commercial zoning systems.\u003c\/p\u003e\n\u003cp\u003eThe EURD-5-MA15S fits 5-inch round ductwork and is suited for air quality and zone control installations where a reliable, bidirectional actuated damper is required. The powered-open, powered-closed operation makes it appropriate for zoning applications where fail-safe spring return is not preferred. It is commonly installed in forced-air systems alongside zone control boards that switch 24-volt signals to open and close individual zones on demand.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSingle-blade round damper sized for 5-inch round duct\u003c\/li\u003e\n  \u003cli\u003e24-volt, two-position motor actuator — powered open and powered closed\u003c\/li\u003e\n  \u003cli\u003e3-wire hookup: common, power-open leg, power-closed leg\u003c\/li\u003e\n  \u003cli\u003eLED position indicators — red for fully closed, green for fully open\u003c\/li\u003e\n  \u003cli\u003eLEDs confirm full blade travel before illuminating, serving as a position failsafe\u003c\/li\u003e\n  \u003cli\u003eNo spring return required — motor drives the blade in both directions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style motorized damper replacement or new-installation component for 5-inch round ductwork in residential and light-commercial forced-air zoning and air quality systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed HVAC technician or qualified sheet metal mechanic. De-energize the zone control board and disconnect 24-volt power to the damper circuit before wiring or replacing the actuator. Connect the 3-wire harness to the zone board per the board manufacturer's wiring diagram, observing the common, power-open, and power-closed terminals. Verify full blade travel and confirm LED indicator response before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: URD Motorized Damper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Voltage\u003c\/strong\u003e: 24 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Operation\u003c\/strong\u003e: Two-position, powered open and powered closed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWires to Motor\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Air Quality\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: EWC CONTROLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: EURD-5-MA15S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EWC CONTROLS","offers":[{"title":"Default Title","offer_id":51344683958578,"sku":"EURD-5-MA15S","price":205.29,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310554824.jpg?v=1782040272","url":"https:\/\/voomisupply.com\/products\/ewc-controls-eurd-5-ma15s-5-inch-round-motorized-damper","provider":"Voomi Supply","version":"1.0","type":"link"}
