Ngaphambi kokuba ukhethe umlawuli wombane weTV, kubalulekile ukuba uqiniseke ukuba unayo imfuno. Uninzi lwezixhobo zasemakhaya zanamhlanje zixhotywe zizinzi zokuzimela, ezinokukwazi ukuhlangabezana ngokugqithiseleyo ngophawu oluphezulu lwamandla kumnatha. Kodwa ukuba intanethi ekhaya lakho ayikwazi ukuziqhayisa ngesantya esiphezulu okanye kukho iimeko zokungaphumeleli kwezixhobo ngenxa yokuqhubeka kwamandla, unokucinga ngokuthenga le fowuni.
Iintlobo zezilawuli zombane
Ngokupheleleyo, i-voltage regulators ye-LCD, i-LED kunye neTV ye-TV iyahlula zibe ziintlobo ezine, ezahlukileyo kwisixhobo nakwiipropati.
- Ukulungiswa kohlobo lwe-relay zineendleko eziphantsi kakhulu, kodwa uvimba lwazo lukhawuleza, kwaye ukuguqulwa kwamandla kwimveliso kunokufikelela kwi-15%.
- I-Servomotor okanye i-stabilizers ye-mechanical ixabiso elincinci ngaphezu kokuguqulwa kwangaphambili, kodwa ubomi babo benkonzo bukhulu kakhulu. Impendulo yodwa yale fowuni ngumsebenzi othe ngcipheko kunye nesidingo sokutyelela ngokukhawuleza isikhungo seenkonzo ukuba sithathe indawo yokutshiza.
- I-Thyristor okanye i-triac yamandla okuqinisela kwi-TV isethi ezininzi zokuyeka ukukhetha kwabo. Kuyilo lwabo alukho iindawo ezihambayo (njengeibhothi), zikhawuleza zilinganisa ukuxhatshazwa. Kodwa lo mzekelo ukwesaba ukutshisa (ukutshisa i-thyristors), kubiza, kwaye kudala inethiwekhi ukuphazamiseka okungadingekile.
- Ikhethelo elikhethekileyo phakathi kwamagunya okulawula i-plasma kunye ne-TV entsha yesizukulwana
umsebenzi wenguqu ephindwe kabini. Ayinanto engabonakaliyo, inomlinganiselo omkhulu wamandla angenayo, angaphazamisi inethiwekhi kwaye ivelisa kakhulu. Ziyabiza kakhulu, kodwa le nkqubo isondeleyo kwaye iphephile kakhulu.
Nangona kunjalo, ungakulibali malunga noko kwathethwa ekuqaleni kwezinto eziphathekayo: ii-TV ezininzi zanamhlanje zixhotyiswe nge-auto-voltage system. Kule meko, impendulo kumbuzo wokuba ufuna i-stabilizer yeTV, unokuziphawula kuphela. Ewe, inokuthengwa ngenxa yokukhathazeka, kodwa inokubaluleka ngokwenene ukuba unesibhubhu okanye i-TV yoshicilelo lwaluhlobo oludala. Ukuba unomzekelo omtsha, ukuthenga le fowuni kuya kuba yinkcitho yemali. Okukhethiweyo, njenjalo, nje kuwe!
