Ƙirar ƙira guda uku da aka sake maimaitawa: ƙirar sake sakewa mai ban sha'awa, ƙirar ƙararrawar wutar lantarki, ƙirar wutar lantarki na iya rage ƙarancin aiki zuwa sifili. Wannan yana nufin cewa lokacin da babban mai motsa jiki ya kasa, zai iya canzawa zuwa mai kunnawa jiran aiki ci gaba; Ana haɗa na'urori masu ƙarfi da yawa, kuma na'urorin ƙara ƙarfin wutar lantarki suna da daidaituwa sosai.

Abubuwan haɓaka biyu suna jiran juna kuma suna da sauƙin maye gurbin; Ana ba da su ta hanyar samar da wutar lantarki da yawa a layi daya, kuma kwamfutar na iya saka idanu da daidaita yanayin aikin wutar lantarki ta atomatik.

Tsarin kulawa da hankali da kulawa, sanye take da hanyar sadarwa ta PC na waje. Cikakken aikin software na sarrafa kwamfuta, tare da aikin ganowa ta atomatik, gano bayanan fasaha, tsarin kulawa, da sauran ayyuka.

Matakan kariyar da aka haɗa da aka canza daga tsarin ƙirar ƙira na iya rage lalacewar kayan aiki. Wannan injin ba shi da kariyar bidiyo; Matsakaicin igiyoyin wutar lantarki yana da girma da yawa, zafi fiye da kima, kan tashin hankali, rashin kariyar lokaci, kariyar walƙiya.

Ƙarfin wutar lantarki, kan-a halin yanzu, ƙarancin ƙarfin lantarki, yawan zafin jiki, gajeriyar kewayawa, da kariya ta walƙiya. A lokaci guda, ana iya karanta duk sigogin fasaha ta hanyar LCD. Duk kayan wutan lantarki suna canza kayan wuta tare da inganci mai girma, kewayon daidaitawa mai faɗi, da ƙarfi mai ƙarfi don daidaitawa ga canje-canjen ƙarfin lantarki na waje. Zane-zane na sauye-sauyen zafi yana sa amplifier na wutar lantarki da sauyawar wutar lantarki yana goyan bayan zafi-swap, wanda ya dace don gyarawa da kiyayewa, kuma yana inganta aminci.

Karamin tsari da kyakkyawan bayyanar, tare da ginannen fan mai ƙarfi mai sanyaya.
