Rated at 18 lb-in of torque with a 15-second travel time, it delivers reliable blade positioning without the need for ongoing maintenance. The unit ships with an integrated wiring terminal block for clean, straightforward field connections. A NEMA1-rated housing protects the motor in conditioned-air environments, and the actuator can be mounted in any orientation, giving installers flexibility during rough-in and retrofit applications. UL Listed for code-compliant installations.\u003c\/p\u003e\n\u003cp\u003eThis actuator is suited for use in zoned forced-air systems where individual dampers must be independently driven open and closed in response to thermostat or zone controller signals. The EMA15S is compatible with standard 24 VAC zone control panels and works with dampers requiring a 3-wire power-open\/power-close drive signal. Dual end-stop adjustments allow field-setting of the maximum open and minimum close blade positions, making it adaptable to varying duct geometries and airflow requirements. A positional arrow on the actuator body provides at-a-glance visual confirmation of blade travel status. An optional auxiliary end-switch, Model S1A, can be added when end-of-travel feedback is required by the control system.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e24 VAC 3-wire power-open\/power-close operation for direct zone controller compatibility\u003c\/li\u003e\n  \u003cli\u003e18 lb-in torque rating with 15-second travel time for positive damper blade positioning\u003c\/li\u003e\n  \u003cli\u003eDual end-stop adjustments for field-configurable maximum open and minimum close positions\u003c\/li\u003e\n  \u003cli\u003eIntegrated wiring terminal block simplifies field wiring connections\u003c\/li\u003e\n  \u003cli\u003eNEMA1-rated housing suitable for conditioned-area installation in any orientation\u003c\/li\u003e\n  \u003cli\u003eUL Listed; includes 5-year manufacturer warranty\u003c\/li\u003e\n  \u003cli\u003eOptional Model S1A auxiliary end-switch available for end-of-travel feedback\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 24 VAC zone control systems requiring a 3-wire power-open\/power-close motor actuator.

De-energize the zone control panel and associated air handler before connecting or disconnecting the actuator. Verify the control panel output is rated for a 3-wire power-open\/power-close actuator before wiring. Actuator orientation is flexible, but the unit must be installed within a conditioned space as specified by the NEMA1 housing rating.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 24 VAC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePower Consumption\u003c\/strong\u003e: 1.5 W\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTorque\u003c\/strong\u003e: 18 lb-in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTravel Time\u003c\/strong\u003e: 15 seconds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperation Type\u003c\/strong\u003e: 3-wire power-open\/power-close\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHousing Rating\u003c\/strong\u003e: NEMA1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eListing\u003c\/strong\u003e: UL Listed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: 5 years\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: EMA15S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EWC CONTROLS","offers":[{"title":"Default Title","offer_id":51343436448050,"sku":"EMA15S","price":177.05,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310554844.jpg?v=1782021441","url":"https:\/\/voomisupply.com\/products\/ewc-controls-ema15s-motor-actuator-24-vac-18-lb-in","provider":"Voomi Supply","version":"1.0","type":"link"}
