Ukufezekisa ukusebenza kakuhle konikezelo lwamandla kwibhentshi, kubalulekile ukuqonda imigaqo yayo esisiseko. Unikezelo lwamandla ebhentshini luguqula amandla ombane we-AC ukusuka kwindawo yokuphuma eludongeni ukuya kumandla eDC asetyenziselwa ukunika amandla amacandelo ahlukeneyo ngaphakathi kwekhompyuter. Isebenza ngokuqhelekileyo kwinqanaba elinye legalelo le-AC kwaye libonelela ngee-voltages ezininzi ze-DC, ezifana ne- +12V, -12V, + 5V, kunye + 3.3V.
Ukuguqula amandla egalelo le-AC abe ngumbane we-DC, unikezelo lwamandla ebhentshini lusebenzisa isiguquli ukuguqula amandla ombane aphezulu kunye namandla asezantsi akhoyo engeniso ye-AC abe ngumbane ophantsi kunye nophawu oluphezulu lwangoku lwe-AC. Lo mqondiso we-AC uya kulungiswa kusetyenziswa ii-diode, eziguqula isignali ye-AC ibe yi-voltage ye-DC.
Ukuphucula amandla ombane we-DC, umbane we-desktop usebenzisa ii-capacitors ezigcina intlawulo egqithisileyo kwaye ziyikhulule ngexesha lombane ophantsi, okukhokelela kumbane wokuphuma kwe-DC ozinzile ngakumbi. I-voltage ye-DC ilawulwa kusetyenziswa i-voltage regulator circuit ukuqinisekisa ukuba ihlala ngaphakathi kokunyamezela okuqinileyo, ukuthintela umonakalo kumacandelo. Ukhuseleko olwahlukeneyo, olufana nokhuseleko olugqithisileyo, ukhuseleko olungaphaya, kunye nokhuseleko lwesekethe emfutshane, nalo lwakhelwe kwizixhobo zombane zedesktop ukukhusela umonakalo kumacandelo xa kukho iimpazamo.
Ukuqonda imigaqo esisiseko yonikezelo lwamandla edesktop kunokuncedisa ekukhetheni unikezelo lwamandla olufanelekileyo lwenkqubo yekhompyutha nokuqinisekisa ukusebenza kakuhle.
Kweli nqaku, siza kugubungela iziseko zokuba yintoni umbane webhentshi, indlela yokuwusebenzisa ngokufanelekileyo, kwaye ujonge ntoni xa ukhetha imodeli.
Yintoni iBenchtop Power Supply?
Xa usebenza kwiprojekthi efuna isixa esichanekileyo samandla e-DC, unikezelo lwamandla ebhentshini luza luncedo. Ngokusisiseko umbane omncinci owenzelwe ukuhlala kwibhentshi yakho yokusebenza.
Ezi zixhobo zikwabizwa ngokuba yi-lab power supply, i-DC power supply, kunye ne-programmable power supply. Zilungele umbane kwabo bafuna ukufikelela kumthombo wamandla othembekileyo nekulula ukuwusebenzisa.
Ngelixa kukho iintlobo ezininzi zobonelelo lwamandla kwi-benchtop ekhoyo-kubandakanya ezinemisebenzi yonxibelelwano, iintlobo zemveliso ezininzi, kunye nezineempawu ezahlukeneyo-zonke ziyilelwe ukwenza imisebenzi yakho ibe lula kwaye ichaneke ngakumbi.
Ingaba isebenza kanjani?
Unikezelo lwamandla ebhentshisi sisixhobo esisebenza ngeendlela ezininzi esibonelela ngamandla alawulwayo kwizixhobo zombane. Isebenza ngokuzoba intambo yombane ye-AC ukusuka kwimibhobho engundoqo kunye nokuyihluza ukubonelela ngemveliso ye-DC engaguqukiyo. Inkqubo ibandakanya amacandelo amaninzi, kubandakanywa i-transformer, i-rectifier, i-capacitor, kunye ne-voltage regulator.
Ngokomzekelo, kunikezelo lwamandla ombane, i-transformer ibeka phantsi i-voltage ukuya kwinqanaba elilawulekayo, i-rectifier iguqula i-AC yangoku kwi-DC, i-capacitor ihluza nayiphi na ingxolo eseleyo, kwaye umlawuli we-voltage uqinisekisa imveliso ezinzileyo ye-DC. Ngokukwazi ukulungelelanisa i-voltage kunye namanqanaba angoku kunye nokukhusela izixhobo ezivela kumandla angaphezu kwamandla, umbane we-benchtop sisixhobo esibalulekileyo kwiinkqubo zokuhlola ngokuzenzekelayo, uncedo loqeqesho lweSikolo, njl.
Kutheni ibalulekile nje?
Unikezelo lwamandla ombane okwi-benchtop lusenokungabi sesona sixhobo sinomtsalane kwilebhu yenjineli yombane, kodwa ukubaluleka kwayo akunakubaxwa. Ngaphandle komnye, uvavanyo kunye neprototyping ayizukwenzeka kwasekuqaleni.
Ubonelelo lwamandla eBenchtop lubonelela ngomthombo othembekileyo nozinzileyo wombane wovavanyo kunye nokunika amandla iisekethe zombane. Bavumela iinjineli ukuba zitshintshe amandla ombane kunye nangoku kumacandelo okuvavanya imida yazo, bajonge indlela abaqhuba ngayo kwizicelo ezahlukeneyo, kwaye baqinisekise ukuba baya kusebenza ngokuchanekileyo kwimveliso yokugqibela.
Utyalo-mali kunikezelo lwamandla lwebhentshi esemgangathweni lunokubonakala ngathi yeyona nto ithengwayo. Sekunjalo, ingenza impembelelo ebalulekileyo kwimpumelelo kunye nokusebenza kakuhle koyilo lwe-elektroniki kunye nophuhliso.
