Xa unikezelo lwamandla lusetyenziswa, lunokuqhagamshelwa ngendlela engeyiyo okanye lufutshane.Ukongeza, unikezelo lwamandla ngokwalo lunokungasebenzi kakuhle kwaye lubangele ukuba umbane ophumayo ungasebenzi kakuhle.Ngoko ke, ekuyilweni nasekuveliseni umbane, iinkcukacha zokhuseleko ziyinxalenye ebaluleke kakhulu.Kukho imiba emibini ekukhuselweni kokunikezelwa kwamandla, enye kukuthintela ezinye izesekeli ukuba zitshiswe, kwaye enye kukukhusela kumonakalo.
Ukukhuselwa konikezelo lwamandla ngaphandle ikakhulu kukhuseleko lwe-voltage kunye ne-under-voltage, oku kuthetha ukuba xa i-voltage ephumayo yonikezelo lwamandla iphezulu kakhulu okanye iphantsi kakhulu ukuba ibe yinto engaqhelekanga, umbane uya kuyeka ukusebenza.Oku kubaluleke kakhulu kumatshini wonke, kuba uninzi lwamacandelo abiza kakhulu abuthathaka, kwaye kulula ukutshisa ngenxa yombane ophezulu.
Ukuthintela oku, kuyimfuneko ukubeka iliso kwi-voltage nganye yemveliso yonikezelo lwamandla.Indlela yomyili wamandla kukwenza isampulu yombane ophumayo ngesekethe yesampulu, kwaye isiginali yesampulu iqhagamshelwe kwicandelo lolawulo ngokuthelekisa.Nje ukuba i-voltage ephumayo ingaqhelekanga, umqondiso wesampulu uya kubonakaliswa ngokukhawuleza, kwaye inxalenye yolawulo iya kwaziswa ukuba ivale.Oku kunokukhusela ngokufanelekileyo iindawo zokudibanisa ngasemva.Ingaba unikezelo lwamandla lunokhuseleko olukhawulezayo lwe-overvoltage lubaluleke kakhulu kumatshini wonke.Ukuze kuthintelwe ukutshiswa okubangelwa ngamandla akhoyo ngoku, umbane uxhotyiswe ngefuse.
