Ukunikezwa kwamandla kunepharamitha: isilinganiso se-IP, okungukuthi, isilinganiso esingenalo uthuli nesingenawo amanzi. Sebenzisa i-IP ngezinombolo ezimbili ukukhombisa, inombolo yokuqala ikhombisa izinga lokuvikela izwe eliqinile, nenombolo yesibili
Ikhombisa izinga lokuvikelwa ketshezi kwemishini. Ngokuya ngezinombolo ezahlukahlukene zegobolondo lomkhiqizo, amandla wokuvikela womkhiqizo anganqunywa ngokushesha nangokushesha.
Vele, ukunikezwa kwamandla nakho kunamapharamitha wokuvikela amafushane, ukulayishwa ngokweqile, kanye nokushisa okushisa ngokweqile. Leli phuzu alidingi ukuchazwa ngokweqile, kuyincazelo oyiqondayo.
Q: Yiziphi izinyathelo zokuphepha zokukhetha ukunikezwa kwamandla okufiphaza okungamanzi kwe-LED?
Impendulo:
A.Ukwandisa impilo yensizakalo yomshayeli wamandla kagesi angahlali manzi, kunconywa ukuthi ukhethe imodeli enesilinganiso samandla sokukhipha esingaphezulu esingu-20%. Isibonelo, uma umthwalo ungu-120W, kunconywa ukuthi ukhethe ifayela le- Ukunikezwa kwamandla kagesi okungangenwa ngamanzi okungu-150W, njalonjalo ingathuthukisa ngempumelelo impilo yokuphakelwa kwamandla kagesi.
B. Kuyadingeka ukuthi kubhekwe ukushisa kwemvelo yokusebenza kokuphakelwa kwamandla okungangeni manzi nokuthi ngabe ikhona yini enye imishini yokusiza ukushisa okusizayo. Umthwalo ulingana nokukhuphuka lapho izinga lokushisa elizungezile liphezulu kakhulu, ngakho-ke ugesi ongangeni manzi udinga ukwehliswa
Inani lokukhiphayo.
C, ukusetshenziswa kwesibani samandla emigwaqo kanye namandla kagesi ajwayelekile kufanele bakhethe ukunikezwa kwamandla okuhambisanayo.
D, khetha isitifiketi somkhiqizo esidingekayo kanye nemingcele yokusebenza, imininingwane, efana nesitifiketi se-CE / PFC / EMC / ROHS / CCC, njll.
Q: Kungani ukunikezwa kwamandla okungangeni manzi kwehluleka ukuvula ngokushelela lapho umthwalo uyimoto, isibani noma umthwalo we-capacitive?
Impendulo:
Lapho umthwalo uyimoto, isibani esikhanyayo noma umthwalo we-capacitive, i-current inkulu kakhulu ngesikhathi sokuvula, edlula kude umthwalo ophakeme wamandla okungangenwa ngamanzi, ngakho-ke amandla okuhambisa amanzi ngeke akwazi ukuvula ngokushelela.
