▍Yintoni i-cTUVus & ne-ETL CERTIFICATION?
I-OSHA (i-Occupational Safety and Health Administration), enxulumene ne-US DOL (iSebe lezeMisebenzi), inyanzelisa ukuba zonke iimveliso eziza kusetyenziswa kwindawo yokusebenza kufuneka zivavanywe kwaye ziqinisekiswe yi-NRTL ngaphambi kokuba zithengiswe emarikeni. Imigangatho yovavanyo esebenzayo ibandakanya imigangatho ye-American National Standards Institute (ANSI); Imigangatho ye-American Society for Testing Material (ASTM), imigangatho yeLabhoratri ye-Underwriter (UL), kunye nemigangatho yombutho wokuqaphela okufanayo.
▍OSHA, NRTL, cTUVus, ETL kunye ne-UL inkcazo yamagama kunye nobudlelwane
OSHA:Ushunqulelo loKhuseleko eMsebenzini kunye noLawulo lwezeMpilo. Lumanyano lwe-US DOL (iSebe lezaBasebenzi).
NRTL:Ushunqulelo lweLebhu yoVavanyo eyaMkelwe kuZwelonke. Ijongene noqinisekiso lwaselebhu. Ukuza kuthi ga ngoku, kukho i-18 amaziko ovavanyo lomntu wesithathu avunywe yi-NRTL, kubandakanya iTUV, ITS, MET njalo njalo.
cTUVus:Uphawu lwesatifikethi se-TUVRh eMntla Melika.
ETL:Ufinyezo lweLebhu yoVavanyo loMbane yaseMelika. Yasekwa ngo-1896 nguAlbert Einstein, umqambi waseMelika.
UL:Ushunqulelo lweUnderwriter Laboratories Inc.

| Ukusilela |
| Ukunakana kwebhrendi okuncinci kune-UL | Ukuqondwa okungaphantsi kunoko kwe-UL kwisiqinisekiso secandelo lemveliso |
▍Kutheni i-MCM?
● Inkxaso ethambileyo evela kwisiqinisekiso neteknoloji:Njengelebhu yovavanyo lwamangqina ye-TUVRH kunye ne-ITS kwiSiqinisekiso soMntla waseMelika, i-MCM iyakwazi ukwenza zonke iintlobo zovavanyo kunye nokubonelela ngenkonzo engcono ngokutshintshiselana ngetekhnoloji ubuso ngobuso.
● Inkxaso enzima evela kubuchwepheshe:I-MCM ixhotyiswe ngazo zonke izixhobo zovavanyo lweebhetri ezinkulu, ezinobungakanani obuncinci kunye neeprojekthi ezichanekileyo (oko kukuthi imoto yombane ephathwayo, amandla okugcina, kunye neemveliso zedijithali), ekwazi ukubonelela ngovavanyo lwebhetri ngokubanzi kunye neenkonzo zesatifikethi kuMntla Melika, ukugubungela imigangatho. UL2580, UL1973, UL2271, UL1642, UL2054 njalo njalo.
UL 1973:2022yapapashwa ngomhla wama-25 kuFebruwari. Olu guqulelo lusekwe kwidrafti yeengcebiso ezimbini ezikhutshwe ngoMeyi nango-Okthobha ka-2021. Umgangatho olungisiweyo wandisa uluhlu lwayo, kubandakanywa inkqubo yamandla yomncedisi wesithuthi (umzekelo, ukukhanya kunye nonxibelelwano).
Isihlomelo 7.7 Isiguquli: isiguquli senkqubo yebhetri siya kuqinisekiswa phantsi kwe-UL 1562 kunye ne-UL 1310 okanye imigangatho efanelekileyo. Amandla ombane aphantsi anokuqinisekiswa phantsi kwe-26.6.
Uhlaziyo lwe-7.9: IiSekethe eziKhuselekileyo kunye noLawulo: inkqubo yebhetri iya kubonelela ngokutshintsha okanye i-breaker, ubuncinane obufunekayo ukuba ibe yi-60V endaweni ye-50V. Imfuneko eyongezelelweyo yomyalelo we-overcurrent fuse.
Uhlaziyo lwe-7.12 Iiseli (iibhetri kunye ne-electrochemical capacitor): Kwiiseli ze-Li-ion ezinokutshajwa kwakhona, uvavanyo phantsi kwesihlomelo E lufunekayo, ngaphandle kokuqwalasela i-UL 1642. Iiseli nazo ziyafuneka ukuba zihlalutywe ukuba ziyahlangabezana nemfuno yoyilo olukhuselekileyo, njengezinto eziphathekayo kunye nendawo ye-insulator, ukugubungela i-anode kunye ne-cathode, njl.
Fakela iRhafu yeRhafu ePhakamileyo ye-16: Vavanya ukhuseleko lokutshaja lwesixokelelwano sebhetri enobuninzi bokutshaja bangoku. Kufuneka kuvavanywe nge-120% yezinga eliphezulu lokutshaja.
Faka i-17 yoVavanyo lweSekethe emifutshane: Yenza uvavanyo olufutshane lwesekethe kwiimodyuli zebhetri ezifuna ukufakwa kwefayile okanye utshintsho.
