{"product_id":"mep-4255-actuator","title":"MEP-4255 Actuator","description":"ACTUATOR; 2-Position; 100-240VAC; Fail S MEP-4255\n\nThese compact but powerful direct-coupled ControlSet actuators provide two-position, tri-state, or proportional control for dampers or valves in HVAC systems. Efficient, durable, \u003cstrong\u003ecapacitor-driven fail-safe\u003c\/strong\u003e with switch-selectable direction provides consistent torque in both powered and fail-safe modes. A patented noise reducer provides whisper-quiet operation in both modes. A minimum torque of 25 (MEP-42xx), 45 (MEP-45xx), or 90 (MEP-49xx) in-lb. is available over the 95° angular rotation.\n\nMEP-4xx2 \u003cstrong\u003eproportional\u003c\/strong\u003e models accept either a 0–10 or 2–10 VDC control signal input from a thermostat, controller, or building automation system. “Anti-jitter” circuitry significantly reduces hunting and needless wear (from unnecessary miniscule position changes caused by undamped analog input signals) on the actuator, valve, or damper components. A user-initiated, auto-mapping feature provides more precise equipment control by reassigning the input signal range over a reduced rotation range. These models also feature a switch-selectable, 0–5 or 0–10 (or 1–5 or 2–10) VDC voltage feedback output that is proportional to the actuator position. (MEP-4252 shown in photo.)\n\nMEP-4xx1 \u003cstrong\u003etri-state\/two-position\u003c\/strong\u003e models are designed for use with floating thermostats, controllers, or building automation systems. MEP-4xx4\/4xx5 \u003cstrong\u003etwo-position\u003c\/strong\u003e models are available in 24 VAC\/VDC or 100-240 VAC models.\n\nMEP-4x7x models also have one fully adjustable, built-in SPDT \u003cstrong\u003eauxiliary switch\u003c\/strong\u003e for remote position indication or equipment interface. MEP-497x models include a second fixed switch at 10° from full CW direction. A three-foot cable is included with the switch(es).\n\nMEP-4xxx\u003cstrong\u003eV\u003c\/strong\u003e actuators have brackets with a patented, \u003cstrong\u003equick-mounting\u003c\/strong\u003e mechanism that mounts directly on VFB-43…BC and VFB-46…BC series valve bodies.\n\nAll actuators mount directly to 1\/4- to 5\/8-inch (6 to 16 mm) round shafts or 1\/4- to 7\/16-inch (6 to 11 mm) square shafts, eliminating the need for expensive and complicated linkages. A non-rotation bracket, to prevent lateral movement, is included with each actuator. A gear disengagement button allows easy manual positioning of the actuator.\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable class=\"woocommerce-product-attributes shop_attributes\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eActuator Type\u003c\/th\u003e\n\u003ctd\u003eElectric\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eKMC Controls\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eControl Input\u003c\/th\u003e\n\u003ctd\u003e100-240 VAC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFail-Safe\u003c\/th\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFail-Safe Type\u003c\/th\u003e\n\u003ctd\u003eElectronic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInput Types\u003c\/th\u003e\n\u003ctd\u003eTwo-position\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMounting\u003c\/th\u003e\n\u003ctd\u003eQuickmount\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eNormality (Fail)\u003c\/th\u003e\n\u003ctd\u003eSelectable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePower Supply\u003c\/th\u003e\n\u003ctd\u003e100-240 VAC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSelection Guide\u003c\/th\u003e\n\u003ctd\u003eActuator-Only\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTiming (sec)\u003c\/th\u003e\n\u003ctd\u003e30\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTorque\u003c\/th\u003e\n\u003ctd\u003e25 in-lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Engenuity Systems","offers":[{"title":"Default Title","offer_id":50732323340546,"sku":"KMC7B-33","price":236.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0827\/1839\/2578\/files\/MEP-4975-medium_a37f4b69-f142-492a-87ba-1981c663bda5.jpg?v=1792017637","url":"https:\/\/engenuity.com\/products\/mep-4255-actuator","provider":"Engenuity Systems","version":"1.0","type":"link"}
