Operating on 24 VAC at 1.5 amps, this ND-series damper uses a power open\/power closed, 3-wire configuration with fail-safe LED indicators that let technicians confirm damper position at a glance. The aluminum frame with nylon bushings reduces operating noise, and the motor delivers enough torque for consistent blade control with a 97% leak-proof rating. A quick-connecting terminal block eliminates wire nuts and speeds up commissioning. The motor includes a manual gear release and is UL Listed for field confidence.\u003c\/p\u003e\u003cp\u003eThis damper is designed for duct-mounted zone control in forced-air HVAC systems, particularly those using multi-zone controllers. It suits residential new construction and retrofit zoning work where accurate airflow control across multiple zones is required. The motor is always mounted on the second dimension specified, which simplifies ordering and installation planning. Heat pump systems are supported, and the damper is compatible with network zoning configurations. Rated for ambient temperatures from 0 degrees F to 140 degrees F, it handles the range of conditions found in unconditioned duct chases and mechanical rooms.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePower open\/power closed 3-wire operation with fail-safe LED indicators for quick diagnostic checks\u003c\/li\u003e\n\u003cli\u003e97% leak-proof rating achieved through overlapping blades and a strong positive-stop motor\u003c\/li\u003e\n\u003cli\u003eNylon bushings reduce operating noise for quieter zone control\u003c\/li\u003e\n\u003cli\u003eUL Listed motor with manual gear release for service flexibility\u003c\/li\u003e\n\u003cli\u003eQuick-connecting terminal block eliminates wire nuts and speeds installation\u003c\/li\u003e\n\u003cli\u003eHeat pump compatible and supports network zoning systems\u003c\/li\u003e\n\u003cli\u003eMade in the USA from aluminum construction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with the EWC Controls Ultra-Zone zoning system and other 24 VAC zone control boards that support power open\/power closed damper wiring.

Shut down the air handler and de-energize the control board before wiring the damper. Follow NEC low-voltage wiring practices for the 24 VAC control circuit. Note that the motor is always factory-mounted on the second dimension of the size designation, so confirm duct orientation before ordering or installing.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 12 x 16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 24 VAC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 1.5 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency\u003c\/strong\u003e: 50\/60 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhase\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDamper Type\u003c\/strong\u003e: Zone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Rectangle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmbient Temperature Range\u003c\/strong\u003e: 0 degrees F to 140 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 185 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Silver\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type\u003c\/strong\u003e: Face plate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeat Pump Compatible\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNetwork Zoning\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApprovals\u003c\/strong\u003e: UL Listed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: USA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 21 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 6.8 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: END-12X16-MA15S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EWC CONTROLS","offers":[{"title":"Default Title","offer_id":51344341106994,"sku":"END-12X16-MA15S","price":301.75,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310555036.webp?v=1782033624","url":"https:\/\/voomisupply.com\/products\/ewc-controls-end-12x16-ma15s-motorized-zone-damper-12x16","provider":"Voomi Supply","version":"1.0","type":"link"}
