{"product_id":"automatic-three-phase-changeover","title":"Automatic Three Phase Changeover","description":"An \u003cstrong\u003eAutomatic Three Phase Changeover\u003c\/strong\u003e feature is now the need of the day. It is user-friendly and easy to use. It saves time too. This kit is also a proto-type to automation of the system. In the earlier days (even today at some places) the manual operations are frequent. When the main supply goes off the person manually turns on the generator. In the case of the electrical appliance control using automation causes more safety.\u003cbr\u003e\u003cbr\u003e This \u003cstrong\u003eAutomatic Three Phase Changeover Kit\u003c\/strong\u003e is a prototype for the same which is auto change over to generator when the main supply fails. In this system, we are designing an embedded circuit to control this. In case there are two phases, then the switching will be in the default phase. Three relays are there to control the switching.\u003cbr\u003e\u003cbr\u003e This system can be used to \u003cstrong\u003eautomate the electrical system\u003c\/strong\u003e where switching is required. It also serves for safety in heavy industrial duty. Manual changeover can be replaced by the automatic changeover in the home. The main part of the kit is the microcontroller. We have to convert the 220 V ac supply to 5 v dc from each phase. This 5v supply is given to the microcontroller and it is programmed to fulfill the above requirements. The output of the microcontroller is given to the ULN2803 relay driver. The relay finally selects the phase in terms of the ac voltage.\u003cbr\u003e\u003cbr\u003e\n\u003cdiv class=\"product_info\" style=\"text-align: start;\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eBlock Diagram\u003c\/h3\u003e\n\u003cp\u003e\u003cimg height=\"75%\" width=\"75%\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/files\/LGEC065.jpg?v=1635419585\" style=\"float: none;\"\u003e\u003c\/p\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 : 28 x 24 x 8\u003c\/li\u003e\n\u003cli\u003eWeight (gm): 1000\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 width=\"800\" height=\"400\" src=\"https:\/\/www.youtube.com\/embed\/J12Et0T4dHY\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen=\"\"\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":40708804870325,"sku":"LGEC065","price":1999.0,"currency_code":"INR","in_stock":true},{"title":"READY TO USE","offer_id":40708804903093,"sku":"LGEC065_R","price":2599.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/products\/Automatic-Three-Phase-Changeover.jpg?v=1635419457","url":"https:\/\/kitsguru.com\/es\/products\/automatic-three-phase-changeover","provider":"KitsGuru","version":"1.0","type":"link"}
