Izimo lapho kwenzeka ukuphuma kwamandla okungalindelekile ekhaya noma ehhovisi imininingwane ebalulekile ilahlekile, ivele njalo. Ukuphuma kwamandla akukwazi nje ukubhubhisa imiphumela yamahora amaningi omsebenzi, kodwa futhi kuholele ekuhlulekeni kwezingxenye zekhompyutha. Kulesi sihloko sizobona ukuthi singakhetha kanjani idivayisi ekhethekile evikela ngezinkinga ezinjalo - ukunikezwa kwamandla okungenakuguqulwa.
Ukukhetha i-UPS
I-UPS noma i-UPS - amandla angenakuguqulwa kwamandla - iyisisetshenziswa esakwazi ukunikeza ugesi kwimishini ehlangene nayo. Esimweni sethu, lena ikhompyutha yomuntu siqu. Ngaphakathi kwe-UPS amabhethri nezinsimbi ze-elektroniki zokuphathwa kwamandla. Kunezinqubo eziningi zokukhetha amadivaysi anjalo, futhi ngezansi sizokutshela ukuthi ungabheka nini uma uthenga.
Criterion 1: Amandla
Le parameter ye-UPS ibaluleke kunazo zonke, ngoba inquma ukuthi iwukuvikela okusebenzayo. Okokuqala udinga ukunquma amandla okuphelele wekhompyutha namanye amadivayisi azosizwa "bespereboynik". Enethiwekhi, kunezibalo ezikhethekile ezisiza ukuthila ukuthi bangaki ama-watts ukucushwa kwakho okudliwayo.
Funda kabanzi: Indlela ongakhetha ngayo ukunikezwa kwamandla kwikhompyutha
Ukusetshenziswa kwamandla kwamanye amadivaysi kungatholakala kwiwebhusayithi yomkhiqizi, ekhadini lomkhiqizo wesitolo se-inthanethi noma kumbhalo womsebenzisi. Okulandelayo udinga ukwengeza izinombolo eziholele.
Manje sibheke izici ze-UPS. Amandla ayo awalinganiselwe kuma-watts (W), kodwa ku-volt-amperes (VA). Ukuze uthole ukuthi ngabe idivaysi ethile izosithatha, kubalulekile ukwenza izibalo ezithile.
Isibonelo
Sinomshini odla ama-watts angu-350, uhlelo lwesipikha - ama-watts angu-70 kanye nokuqapha - cishe ama-watts angu-50. Inani
350 + 70 + 50 = 470 W
Inani esilitholile libizwa ngokuthi amandla asebenzayo. Ukuze uthole ngokugcwele, udinga ukwandisa leli xabiso ngesici 1.4.
470 * 1.4 = 658 VA
Ukwandisa ukuthembeka nokuqina kwaleso sonke isimiso, sidinga ukungeza kule nzuzo 20 - 30%.
658 * 1.2 = 789.6 VA (+ 20%)
noma
658 * 1.3 = 855.4 VA (+ 30%)
Izibalo zibonisa ukuthi izidingo zethu zihambelana nokunikezwa kwamandla okungenakuguqulwa ngamandla okungenani 800 VA.
Criterion 2: Ukuphila kwebhethri
Lesi esinye isici, ngokuvamile esiboniswe ekhadini lezinto futhi sithinta ngokuqondile intengo yokugcina. Kuncike emandleni kanye nekhwalithi yamabhethri, okuyiyona ingxenye enkulu ye-UPS. Lapha sidinga ukunquma ukuthi yiziphi izenzo esizozithatha uma kutholakala ugesi. Uma nje udinga ukuqedela umsebenzi - gcina imibhalo, vala izinhlelo zokusebenza - amaminithi angu-2-3 ayokwanela. Uma uhlela ukuqhubeka uhlobo oluthile lomsebenzi, isibonelo, uqedele nxazonke noma ulinde ukucubungula idatha, khona-ke kuzodingeka ubheke kumadivayisi amaningi anamandla.
Criterion 3: Voltage and Protection
Lezi zimingcele zihlobene eduze. I-voltage encane etholakala kwinethiwekhi (okokufaka) nokuphambuka kusuka ekuqanjweni kuyizinto ezithinta isikhathi sokusebenza nokusebenza kwe-UPS. Kufanelekile ukunaka ukubaluleka lapho idivayisi ishintshe amandla ebhetri. Ukunciphisa inombolo kanye nokuphakama okuphambukayo, kancane kancane kuzofakwa emsebenzini.
Uma inethiwekhi kagesi ekhaya lakho noma ehhovisi ingaqiniseki, okungukuthi, ukuxhaswa noma ukujula kuyabonakala, ngakho-ke kuyadingeka ukhethe amadivayisi anezivikelo ezifanele. Ikuvumela ukuba unciphise umthelela ekukhuphukeni kwemishini futhi ukwandise inani elidingekayo emsebenzini, ngoba kuncishisiwe. Amadivaysi ane-voltage controller eyakhelwe ngaphakathi enamandla futhi emakethe, kepha sizoxoxa ngakho emva kwesikhathi.
Criterion 4: Uhlobo lwe-UPS
Kunezinhlobo ezintathu ze-UPS, ezihlukile esimweni sokusebenza nezinye izici.
- Okungaxhunyiwe ku-intanethi noma ukugcina ube nesimiso esilula - uma kwenzeka ukuhluleka kwamandla, ukugcwaliswa kwe-elektroniki kushintshela ukunikezwa kwamandla okuvela kwamabhethri. Ukungahleleki kwalawo madivaysi kukhona amabili - ukulibaziseka okukhulu uma ushintsha nokuvikeleka okubuthakathaka ekubhekaneni nokungahloniphi. Isibonelo, uma i-voltage yehla kancane, khona-ke idivayisi ishintsha ibhethri. Uma amaconsi ejwayelekile, khona-ke i-UPS izovula kaningi, okuholela ekuwohlokeni kwayo okusheshayo.
- I-line-interactive. Amadivaysi anjalo afakwe izindlela ezithuthukisiwe zokulawula umthamo futhi akwazi ukumelana nokuxhaswa okujulile. Izikhathi zabo zokushintsha ziphansi kakhulu kunezipele.
- Ukuguqulwa okuphindwe kabili ku-intanethi. Lawa ma-UPS anesifunda esiyinkimbinkimbi kunazo zonke. Igama labo lizikhulumela ngokwalo - Umshini wokufaka we-AC uguqulwa ku-DC, futhi ngaphambi kokuba udliwe ezixhumi eziphumayo, futhi ku-AC. Le ndlela ivumela ukuthola umthamo ophephile kakhulu owenziwe. Amabhethri kumadivayisi anjalo ahlale ehlanganiswa esiteshini sokunikezwa amandla (ku-intanethi) futhi ayidingi ukushintshwa lapho okwamanje kugridi yamandla ibonakala.
Amadivaysi avela esigabeni sokuqala anezindleko eziphansi kakhulu futhi afanelekile ukuxhuma amakhompyutha asekhaya nasehhovisi. Uma i-PC ifakwe neyunithi yokunikezela yamandla ephezulu ngokuvikelwa emagqumeni amandla, khona-ke i-UPS yokusekelayo ayiyona into embi kakhulu. Imithombo yokuxhumana ayikho ebiza kakhulu, kepha ibe nemithombo ephezulu yomsebenzi futhi ayidingi ukuthuthukiswa okungeziwe kusuka ohlelweni. I-UPS e-inthanethi - amadivayisi wezobuchwepheshe obuphezulu kunazo zonke, ezithinta intengo yawo. Ziklanyelwe ukwenza amandla okusebenza kanye namaseva, futhi ingakwazi ukugijima kuma-betri isikhathi eside. Akufanelekile ukusetshenziswa kwekhaya ngenxa yezinga eliphakeme lomsindo.
Criterion 5: I-Connector Kit
Into elandelayo okufanele uyiqaphele yizixhumanisi eziphumayo zamadivayisi wokuxhuma. Ezimweni eziningi, ikhompiyutha nezinsimbi zifuna amasokedi ajwayelekile. CEE 7 - "izisekelo ze-euro".
Kunezinye izindinganiso, isibonelo, IEC 320 C13, kubantu abavamile okuthiwa ikhompyutha. Ungakhohliswa yilokhu, ngoba ikhompyutha ingaxhunyaniswa kuphela nezixhumi ezinjalo besebenzisa ikhebula elikhethekile.
Ezinye izinto ezingenakuguqulwa kwamandla nazo zingavikela imigqa yocingo kanye namaphakethe enethiwekhi wekhompyutha noma router kusuka emthelela omubi. Amadivayisi anjalo anezixhumi ezihambelanayo: Rj-11 - ngefoni, Rj-45 - ikhebula lenethiwekhi.
Yiqiniso, udinga ukunakekela inombolo edingekayo yezimboni ukunikeza amandla kuwo wonke amadivayisi asolwayo. Sicela uqaphele ukuthi akuzona zonke izisekelo "eziwusizo ngokulinganayo." Amanye angase abe amandla webhethri (UPS), kanti abanye kungenzeka. Lezi zikhathi eziningi zisebenza ngesikhuseli esakhiwe ngaphakathi esinikezela ukuvikela ukungazinzi kwenethiwekhi kagesi.
Criterion 6: Amabhethri
Njengoba amabhethri avuselelekayo yiyona ingxenye enkulu kakhulu ethwele, angase ahluleke noma amandla awo angeke akwanele ukuqinisekisa isikhathi sokusebenza esidingekayo kuwo wonke amadivayisi axhunyiwe. Uma kunokwenzeka, khetha i-UPS ngamasekhondi angeziwe namabhethri ashisayo.
Criterion 7: Isofthiwe
Isofthiwe efika ngezikhwebu ngamanye amadivaysi, isiza ukuqapha isimo samabhethri kanye nemodi yokusebenza ngokuqondile kwesikrini sokuqapha. Kwezinye izimo, isofthiwe ingasindisa futhi imiphumela yomsebenzi futhi igcwalise kahle iseshini ye-PC ngenkathi inciphisa izinga lokushaja. Kufanelekile ukunaka i-UPS enjalo.
Criterion 8: Bonisa isikrini
Isikrini esingaphambili kwephaneli yedivaysi ikuvumela ukuba uhlole ngokushesha imingcele bese uthola ukuthi ngabe kukhona ukuphuma kwamandla.
Isiphetho
Kulesi sihloko sizame ukuhlaziya izindlela ezibaluleke kakhulu zokukhetha amandla angenakuguqulwa kwamandla ngangokunokwenzeka. Yiqiniso, kukhona nokubukeka nobukhulu, kodwa lezi zivele ziyimingcele encane futhi zikhethiwe kuphela ngokuvumelana nesimo futhi, mhlawumbe, ngokuhambisana nokunambitheka komsebenzisi. Ukubamba iqhaza, singasho lokhu okulandelayo: okokuqala udinga ukunaka amandla namandla nenamba edingekayo yamasokhethi, bese ukhetha uhlobo, oluqondiswa usayizi wesabelomali. Ungalandeli amadivaysi ashibhile, njengoba zivame kakhulu izinga eliphansi futhi esikhundleni sokuvikelwa bangakwazi "ukubulala" i-PC oyikhonzile.
