Ukuze kufezwe ukusebenza kahle kokunikezwa kwamandla e-benchtop, kubalulekile ukuqonda izimiso zayo eziyisisekelo. Ukunikezwa kwamandla e-benchtop kuguqula amandla okufaka e-AC avela odongeni abe amandla e-DC asetshenziselwa ukunika amandla izingxenye ezahlukene ngaphakathi kwekhompyutha. Ngokuvamile isebenza kokufakwayo kwe-AC kwesigaba esisodwa futhi inikeza ama-voltage amaningi okukhipha e-DC, njenge-+12V, -12V, +5V, kanye ne-+3.3V.
Ukuze kuguqulwe amandla okufaka e-AC abe amandla e-DC, ugesi we-benchtop usebenzisa i-transformer ukuguqula amandla okufaka e-AC aphezulu kanye namandla aphansi abe yi-voltage ephansi kanye nesignali ye-AC yamanje ephezulu. Lesi signali se-AC sibe sesilungiswa kusetshenziswa ama-diode, aguqula isignali ye-AC ibe yi-voltage ye-DC eshaya ngamandla.
Ukuze kulungiswe i-voltage ye-DC eshayayo, ugesi wedeskithophu usebenzisa ama-capacitor agcina ishaja eyengeziwe futhi ayikhulule ngezikhathi ze-voltage ephansi, okuholela ku-voltage yokuphuma ye-DC eqinile kakhudlwana. I-voltage ye-DC ibe isilawulwa kusetshenziswa isekethe yokulawula i-voltage ukuqinisekisa ukuthi ihlala ngaphakathi kokubekezelelana okuqinile, ivimbela ukulimala kwezingxenye. Ukuvikelwa okuhlukahlukene, njengokuvikelwa kwe-overvoltage, ukuvikelwa kwe-overcurrent, kanye nokuvikelwa kwe-short circuit, nakho kwakhelwe ezimpahleni zamandla zedeskithophu ukuvimbela ukulimala kwezingxenye uma kwenzeka amaphutha.
Ukuqonda izimiso eziyisisekelo zokunikezwa kwamandla edeskithophu kungasiza ekukhetheni ukunikezwa kwamandla okufanele kohlelo lwekhompyutha nokuqinisekisa ukusebenza kahle.
Kulesi sihloko, sizoxoxa ngezinto eziyisisekelo zokuthi iyini i-benchtop power supply, ukuthi isetshenziswa kanjani kahle, nokuthi yini okufanele uyibheke lapho ukhetha imodeli.
Kuyini i-Benchtop Power Supply?
Uma usebenza kuphrojekthi edinga inani eliqondile lamandla e-DC, ugesi osebenza phezu kwebhentshi ungaba usizo. Empeleni ugesi omncane owenzelwe ukuhlala ebhentshini lakho lokusebenza.
Lawa madivayisi aziwa nangokuthi izinsiza zamandla zelebhu, izinsiza zamandla ze-DC, kanye nezinsiza zamandla ezihlelwayo. Zilungele ama-elekthronikhi kulabo abadinga ukufinyelela emthonjeni wamandla othembekile futhi okulula ukuwusebenzisa.
Nakuba kunezinhlobo eziningana zamandla kagesi atholakalayo – okuhlanganisa nalawo anemisebenzi yokuxhumana, izinhlobo zokukhipha okuningi, kanye nalawo anezici ezahlukahlukene – konke kuklanyelwe ukwenza imisebenzi yakho ibe lula futhi inembe kakhudlwana.
Kusebenza kanjani?
Ukunikezwa kukagesi kwe-benchtop kuyithuluzi eliguquguqukayo elihlinzeka ngamandla alawulwayo kumadivayisi kagesi. Lisebenza ngokudweba umugqa wamandla we-AC kusuka kuma-mains bese liwuhlunga ukuze linikeze umphumela we-DC oqhubekayo. Le nqubo ihilela izingxenye eziningana, kufaka phakathi i-transformer, i-rectifier, i-capacitor, kanye ne-voltage regulator.
Isibonelo, ekuhlinzekweni kwamandla okuqondile, i-transformer yehlisa i-voltage iye ezingeni elilawulekayo, i-rectifier iguqula i-AC current ibe yi-DC, i-capacitor ihlunga noma yimuphi umsindo osele, kanti i-voltage regulator iqinisekisa ukuphuma kwe-DC okuzinzile. Njengoba inekhono lokulungisa amazinga e-voltage namanje kanye nokuvikela amadivayisi emandleni angaphezu kwamandla, i-benchtop power supply iyithuluzi elibalulekile lezinhlelo zokuhlola ezizenzakalelayo, usizo lokuqeqesha esikoleni, njll.
Kungani kubalulekile?
Ukunikezwa kukagesi okusebhentshini kungase kungabi yithuluzi elihle kakhulu elebhu yonjiniyela kagesi, kodwa ukubaluleka kwalo akunakuphikiswa. Ngaphandle kwalo, ukuhlola nokwenza amaphrothotayipi ngeke kwenzeke kwasekuqaleni.
Izinsiza zikagesi ze-Benchtop zinikeza umthombo we-voltage othembekile nozinzile wokuhlola nokunika amandla amasekethe kagesi. Zivumela onjiniyela ukuthi bashintshe i-voltage kanye ne-current kuya ezingxenyeni ukuze bahlole imikhawulo yazo, babheke ukuthi zisebenza kanjani ezinhlelweni ezahlukene, futhi baqinisekise ukuthi zizosebenza kahle kumkhiqizo wokugcina.
Ukutshala imali ekuhlinzekweni kwamandla kagesi okusezingeni eliphezulu kungase kungabonakali njengokuthenga okukhazimulayo kakhulu. Noma kunjalo, kungaba nomthelela omkhulu empumelelweni nasekusebenzeni kahle komklamo kanye nentuthuko ye-elekthronikhi.
