Ukuze kuzuzwe ukusebenza kahle kokuphakelwa kwamandla kwebhentshi, kubalulekile ukuqonda izimiso zayo eziyisisekelo. Ukunikezwa kwamandla ebhentshini kuguqula amandla okufaka e-AC asuka odongeni abe amandla e-DC asetshenziselwa ukunika amandla izingxenye ezihlukahlukene ngaphakathi kwekhompyutha. Ivamise ukusebenzisa okokufaka kwe-AC kwesigaba esisodwa futhi inikeza amandla kagesi amaningi okukhiphayo e-DC, njenge-+12V, -12V, +5V, kanye +3.3V.
Ukuze uguqule amandla okufakwayo e-AC abe amandla e-DC, indawo yamandla ebhentshini isebenzisa isiguquli ukuze iguqule amandla kagesi aphezulu kanye namandla okufaka we-AC aphansi abe amandla kagesi aphansi kanye nesiginali ye-AC ephezulu. Le siginali ye-AC ibe isilungiswa kusetshenziswa ama-diode, aguqula isignali ye-AC ibe i-voltage ye-DC edonsayo.
Ukuze wenze bushelelezi i-voltage ye-DC ephehlayo, indawo kagesi yedeskithophu isebenzisa ama-capacitor agcina ukushajwa okweqile futhi ayikhulule ngezikhathi zamandla kagesi aphansi, okuholela ekuphumeni kwe-DC ezinze kakhudlwana. I-voltage ye-DC ibe isilawulwa kusetshenziswa i-voltage regulator circuit ukuqinisekisa ukuthi ihlala ngaphakathi kokubekezelelana okuqinile, ukuvimbela ukulimala ezingxenyeni. Ukuvikela okuhlukahlukene, okufana nokuvikela i-overvoltage, ukuvikelwa kwe-overcurrent, nokuvikelwa kwesekethe emfushane, nakho kwakhelwe ezintweni zamandla edeskithophu ukuvimbela ukulimala kwezingxenye uma kwenzeka kuba namaphutha.
Ukuqonda izimiso eziyisisekelo zokuphakelwa kwamandla edeskithophu kungasiza ekukhetheni ukunikezwa kwamandla okufanelekile kwesistimu yekhompyutha nokuqinisekisa ukusebenza okuphelele.
Kulesi sihloko, sizofaka izisekelo zokuthi kuyini ukunikezwa kwamandla kwebhentshi, ukuthi usetshenziswa kanjani kahle, nokuthi yini okufanele uyibheke lapho ukhetha imodeli.
Iyini i-Benchtop Power Supply?
Uma usebenza kuphrojekthi edinga inani elinembile lamandla e-DC, ukunikezwa kwamandla kwebhentshi kungaba usizo. Empeleni indawo encane kagesi eklanyelwe ukuhlala ebhentshini lakho lomsebenzi.
Lawa madivayisi aziwa nangokuthi izinsiza zamandla elebhu, izinto zikagesi ze-DC, nezinto zikagesi ezihlelekayo. Alungele okogesi kulabo abadinga ukufinyelela kumthombo wamandla onokwethenjelwa nokusebenziseka kalula.
Yize kunezinhlobo ezimbalwa zamandla e-benchtop atholakalayo–okuhlanganisa lawo anemisebenzi yokuxhumana, izinhlobo zemikhiqizo eminingi, kanye nalezo ezinezici ezihlukahlukene—zonke zakhelwe ukwenza imisebenzi yakho ibe lula futhi inembe kakhudlwana.
Isebenza kanjani?
I-benchtop power supply iwucezu lwesisetshenziswa esishintshashintshashintshayo esinikeza amandla alawulwayo emishinini kagesi. Isebenza ngokudweba ulayini wamandla we-AC kusuka kumapayipi amakhulu nokuyihlunga ukuze inikeze okukhiphayo okungaguquki kwe-DC. Inqubo ibandakanya izingxenye eziningana, okuhlanganisa i-transformer, i-rectifier, i-capacitor, nesilawuli se-voltage.
Isibonelo, kugesi olayini, i-transformer yehlisa i-voltage ibe sezingeni elilawulekayo, i-rectifier iguqulela i-AC yamanje ibe yi-DC, i-capacitor ihlunga noma yimuphi umsindo osele, futhi isilawuli sikagesi siqinisekisa ukuphuma okuzinzile kwe-DC. Ngokukwazi ukulungisa amaleveli kagesi kanye namanje nokuvikela amadivayisi amandla angaphezu kwamandla, ukunikezwa kwamandla kwebhentshi kuyithuluzi elibalulekile lamasistimu okuhlola okuzenzakalelayo, usizo lokuqeqesha Isikole, njll.
Kungani ibalulekile?
Ukunikezwa kwamandla ebhentshini kungase kungabi ucezu lwesisetshenziswa esihle kakhulu elebhu kanjiniyela kagesi, kodwa ukubaluleka kwawo angeke kweqiswe. Ngaphandle kokukodwa, ukuhlolwa kanye ne-prototyping ngeke kwenzeke kwasekuqaleni.
Amandla kagesi e-Benchtop ahlinzeka ngomthombo onokwethenjelwa nozinzile wamandla kagesi ukuze ahlolwe futhi anike amandla amasekhethi kagesi. Bavumela onjiniyela ukuthi baguqule amandla kagesi kanye namanje ezingxenyeni ezithile ukuze bahlole imikhawulo yabo, babheke ukuthi basebenza kanjani ezinhlelweni ezihlukene, futhi baqinisekise ukuthi bazosebenza kahle emkhiqizweni wokugcina.
Ukutshala imali ekunikezeni amandla ebhentshini lekhwalithi kungase kungabonakali njengokuthenga okuhle kakhulu. Noma kunjalo, ingaba nomthelela omkhulu empumelelweni nasekusebenzeni kahle komklamo nokuthuthukiswa kwe-elekthronikhi.
