▍Iyini i-cTUVus & ne-ETL CERTIFICATION?
I-OSHA (Occupational Safety and Health Administration), exhumene ne-US DOL (Umnyango Wezabasebenzi), ifuna ukuthi yonke imikhiqizo ezosetshenziswa emsebenzini kufanele ihlolwe futhi iqinisekiswe yi-NRTL ngaphambi kokuba idayiswe emakethe. Amazinga okuhlola asebenzayo ahlanganisa amazinga e-American National Standards Institute (ANSI); Amazinga e-American Society for Testing Material (ASTM), amazinga e-Underwriter Laboratory (UL), kanye namazinga enhlangano yokuqaphela mutual yefekthri.
▍OSHA, NRTL, cTUVus, ETL kanye nencazelo yamagama e-UL kanye nobudlelwano
OSHA:Isifinyezo Sokuphepha Kwasemsebenzini Nokuphathwa Kwezempilo. Kuyinhlangano ehlangene ye-US DOL (Umnyango Wezabasebenzi).
I-NRTL:Isifinyezo Selabhorethri Yokuhlola Eyaziwa Kuzwelonke. Iphethe ukugunyazwa kwelebhu. Kuze kube manje, kunezikhungo zokuhlola ezivela eceleni eziyi-18 ezigunyazwe yi-NRTL, okuhlanganisa i-TUV, ITS, MET njalonjalo.
cTUVus:Uphawu lwesitifiketi se-TUVRh eNyakatho Melika.
I-ETL:Isifinyezo se-American Electrical Testing Laboratory. Yasungulwa ngo-1896 ngu-Albert Einstein, umsunguli waseMelika.
UL:Ukulinganisa kwenkampani Underwriter Laboratories Inc.
▍Umehluko phakathi kwe-cTUVus, i-ETL ne-UL
| Into | UL | cTUVus | I-ETL |
| Kusetshenziswe okujwayelekile | Ngokufanayo | ||
| Isikhungo esifanelekile ukuthola irisidi yesitifiketi | I-NRTL (ilabhorethri egunyazwe kuzwelonke) | ||
| Imakethe esetshenziswayo | I-North America (US ne-Canada) | ||

▍Kungani i-MCM?
● Ukusekelwa Okuthambile okuvela kuziqu nobuchwepheshe:Njengelebhu yokuhlola yofakazi ye-TUVRH kanye ne-ITS kusitifiketi saseNyakatho Melika, i-MCM iyakwazi ukwenza zonke izinhlobo zokuhlola futhi inikeze isevisi engcono ngokushintshisana ngobuchwepheshe ubuso nobuso.
● Usekelo oluqinile oluvela kubuchwepheshe:I-MCM ifakwe zonke izinto zokuhlola amabhethri amaphrojekthi amakhulu, amancane futhi anembayo (okungukuthi imoto ephathwayo esebenza ngogesi, amandla okugcina, kanye nemikhiqizo yedijithali), ekwazi ukuhlinzeka ngezinsizakalo zokuhlola ibhethri kanye nezitifiketi eNyakatho Melika, ezihlanganisa izindinganiso. UL2580, UL1973, UL2271, UL1642, UL2054 njalonjalo.
UL 1973:2022yashicilelwa ngomhla zingama-25 kuNhlolanja. Le nguqulo isuselwe kokusalungiswa okubili kweziphakamiso ezikhishwe ngoMeyi nango-Okthoba ka-2021. Izinga elishintshiwe landisa ububanzi balo, okuhlanganisa uhlelo lwamandla omsizi wemoto (isb. ukukhanya nokuxhumana).
Faka i-7.7 Transformer: i-transformer yohlelo lwebhethri izogunyazwa ngaphansi kwe-UL 1562 ne-UL 1310 noma amazinga afanelekile. I-voltage ephansi ingagunyazwa ngaphansi kwe-26.6.
Buyekeza 7.9: Izifunda Zokuvikela Nokulawula: isistimu yebhethri izohlinzeka ngeswishi noma isinqamuli, ubuncane bayo obudingekayo ukuze kube ngu-60V esikhundleni sika-50V. Isidingo esingeziwe somyalelo we-overcurrent fuse.
Buyekeza Amaseli angu-7.12 (amabhethri ne-electrochemical capacitor): Kumaseli e-Li-ion aphinde ashajwa, ukuhlolwa ngaphansi kwe-annex E kuyadingeka, ngaphandle kokucabangela i-UL 1642. Amaseli ayadingeka futhi ukuthi ahlaziywe uma ehlangabezana nesidingo sedizayini ephephile, njengempahla nendawo yesivikeli mandla, ukumbozwa kwe-anode ne-cathode, njll.
Faka inkokhiso Yezinga Eliphezulu elingu-16: Hlola ukuvikelwa kokushaja kwesistimu yebhethri ngokushaja okuphezulu kwamandla wamanje. Kudingeka ukuhlola ngo-120% wesilinganiso sokushaja esiphezulu.
Faka Ukuhlolwa Kwesekethe Efushane engu-17: Yenza ukuhlolwa kwesekethi emfushane yamamojula webhethri adinga ukufakwa kwefayela noma ukushintshwa.
