Automatic restart protection is included, while reverse polarity protection is not identified as included in the manufacturer specification.\u003c\/p\u003e\n\u003cbr\u003e\n\u003cp\u003e\u003cstrong\u003eWhat should be checked before ordering EE80251S1-000U-A99?\u003c\/strong\u003e\u003cbr\u003eConfirm the complete SUNON model number, 12 VDC rated supply, 145 mA rated current, 1.7 W rated power, 3200 RPM speed, 41 CFM airflow, 0.18 inH2O static pressure, lubricated sleeve bearing, 80 x 80 x 25 mm housing, 71.5 mm mounting-hole center spacing and two-wire connection. DigiKey identifies the model as obsolete and lists EF80251S1-1000U-A99 as a direct substitute, but mechanical dimensions, electrical characteristics and cooling requirements should still be checked. The related EE80251S1-D170-F99 configuration has different functional wiring and should not automatically be treated as interchangeable.\u003c\/p\u003e\n\u003c\/section\u003e\n\u003c\/main\u003e\u003c\/div\u003e\n\u003c\/div\u003e","brand":"SUNON","offers":[{"title":"Default Title","offer_id":67823719940175,"sku":"LL1-SU- EE80251S1000UA99","price":12.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/7569\/2623\/files\/EE80251S1-000U-A99-01.jpg?v=1792571662","url":"https:\/\/yunshuotrade.com\/products\/sunon-ee80251s1-000u-a99-fan","provider":"yunshuotrade","version":"1.0","type":"link"}
