{"product_id":"blown-fuse-indicator","title":"Electric Blown Fuse Indicator","description":"\u003cp\u003eIn the kit \u003cstrong\u003eBlown Fuse Indicator\u003c\/strong\u003e is a common device that is used in every electrical or electronic equipment or device. Fuse is a protective element of every device which protects the electrical equipment against high voltage. When equipment indicates no power, the cause may be just a blown fuse. Here is a circuit that shows the condition of the fuse through LEDs. This compact circuit is very useful and reliable.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e \u003cstrong\u003ePower Electronic Blown Fuse\u003c\/strong\u003e uses very few components. Under normal conditions (when the fuse is alright), green LED glow. Whereas the red LED remains off. When the fuse blows off, the supply to green LED gets blocked, and because only one LED is in the circuit, the red LED glows. In case of power failure, both LEDs remain ‘off’.\u003c\/p\u003e\n\u003cp\u003eThis \u003cstrong\u003eBlown Fuse Indicator\u003c\/strong\u003e circuit can be easily modified to produce a siren in fuse-blown conditions. An optocoupler (MCT2E) is used to trigger the siren. When the fuse blows, a red LED glows. Simultaneously it switches ‘on the siren. Two LEDs of red and green color can be used. Similarly, two diodes are used to increase the voltage drop, since the two LEDs may produce different voltage drops.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eBlock Diagram\u003c\/h3\u003e\n\u003cdiv id=\"p_info\" style=\"text-align: start;\"\u003e\u003cimg border=\"0\" alt=\"LGKT057\" src=\"https:\/\/i.postimg.cc\/gJ6qYydz\/LGKT057.jpg\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003ePhysical Attributes\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eDimensions (cm) L x W x H : 20 x 15 x 5\u003c\/li\u003e\n\u003cli\u003eWeight (gm): 200\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eProduct Video\u003c\/h3\u003e\n\u003cdiv id=\"p_video\"\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/K1AY5ScKMgs\" height=\"400\" width=\"800\" allowfullscreen=\"\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" frameborder=\"0\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003cdiv id=\"p_video\"\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/6rmErwU5E-k\" height=\"400\" width=\"800\" allowfullscreen=\"\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" frameborder=\"0\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003cdiv id=\"p_video\"\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/Fp37DPZVdRI\" height=\"400\" width=\"800\" allowfullscreen=\"\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" frameborder=\"0\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003c\/div\u003e","brand":"KitsGuru","offers":[{"title":"DO IT YOURSELF","offer_id":40708848156853,"sku":"LGKT057","price":599.0,"currency_code":"INR","in_stock":true},{"title":"READY TO USE","offer_id":40708848189621,"sku":"LGKT057_R","price":699.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/products\/KITSGURU_LGKT057_1.jpg?v=1633524422","url":"https:\/\/kitsguru.com\/de\/products\/blown-fuse-indicator","provider":"KitsGuru","version":"1.0","type":"link"}
