It supports a wide power range—AC 24–240 V or DC 24–125 V—with 50\/60 Hz operation to fit a variety of building automation systems, and includes two auxiliary switches for additional signaling tied to damper position. Two-position operation means the damper is either fully open or fully closed, enabling rapid, decisive movement in response to simple open\/close commands. The SFU-S2 is listed by Belimo as the predecessor to the current SFA-S2, which catalogs show as the replacement model, reflecting the company’s evolution of two-position dampers actuators. Common applications include air damper control in commercial and light-industrial HVAC installations where straightforward two-position actuation and robust torque are required.\u003c\/p\u003e\u003c\/div\u003e","brand":"Belimo","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51676861989166,"sku":null,"price":116.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_812db713-b3d2-4ea1-9baa-edad26eab35e.jpg?v=1769554456","url":"https:\/\/plgautomation.com\/products\/belimo-sfu-s2-damper-actuator-open-close-2-position","provider":"PLG Automation ","version":"1.0","type":"link"}
