▍Kodi cTUVus & ETL CERTIFICATION ndi chiyani?
OSHA (Occupational Safety and Health Administration), yogwirizana ndi US DOL (Department of Labor), ikufuna kuti zinthu zonse zogwiritsidwa ntchito kuntchito ziyenera kuyesedwa ndi kutsimikiziridwa ndi NRTL zisanagulitsidwe pamsika. Miyezo yoyezetsa yogwiritsidwa ntchito ikuphatikiza miyezo ya American National Standards Institute (ANSI); Miyezo ya American Society for Testing Material (ASTM), Miyezo ya Underwriter Laboratory (UL), ndi miyezo ya bungwe lozindikiritsa fakitale.
▍OSHA, NRTL, cTUVus, ETL ndi UL matanthauzo ndi ubale
OSHA:Chidule cha Occupational Safety and Health Administration. Ndi mgwirizano wa US DOL (Department of Labor).
Mtengo wa NRTL:Chidule cha Nationally Recognized Testing Laboratory. Ndiwoyang'anira kuvomerezeka kwa labu. Mpaka pano, pali mabungwe oyesa 18 omwe avomerezedwa ndi NRTL, kuphatikiza TUV, ITS, MET ndi zina zotero.
cTUVus:Chizindikiro cha TUVRh ku North America.
Mtengo wa ETL:Chidule cha American Electrical Testing Laboratory. Idakhazikitsidwa mu 1896 ndi Albert Einstein, woyambitsa waku America.
UL:Malingaliro a magawo a Underwriter Laboratories Inc.
▍Kusiyana pakati pa cTUVus, ETL & UL

▍Chifukwa chiyani MCM?
● Thandizo Lofewa kuchokera ku qualification ndi teknoloji:Monga labu yoyesa mboni ya TUVRH ndi ITS ku North America Certification, MCM imatha kuyesa mitundu yonse ndikupereka ntchito zabwinoko posinthana ukadaulo maso ndi maso.
● Thandizo lolimba laukadaulo:MCM ili ndi zida zonse zoyezera mabatire akuluakulu, ang'onoang'ono komanso olondola (mwachitsanzo, galimoto yamagetsi yamagetsi, mphamvu zosungiramo zinthu, ndi zinthu zamagetsi zamagetsi), zomwe zimatha kupereka ntchito zonse zoyezera batire ndi ziphaso ku North America, zomwe zimakwaniritsa miyezo. UL2580, UL1973, UL2271, UL1642, UL2054 ndi zina zotero.
UL 1973:2022 idasindikizidwa pa 25 February. Mtunduwu umachokera pamalingaliro awiri omwe adaperekedwa mu Meyi ndi Okutobala 2021. Mulingo wosinthidwa umakulitsa kuchuluka kwake, kuphatikiza makina othandizira mphamvu zamagalimoto (mwachitsanzo, kuwunikira ndi kulumikizana).
Zowonjezera 7.7 Transformer: thiransifoma ya makina a batri iyenera kukhala ndi satifiketi pansi pa UL 1562 ndi UL 1310 kapena milingo yoyenera. Magetsi otsika amatha kutsimikiziridwa pansi pa 26.6. Kusintha 7.9: Mayendedwe Otetezera ndi Kulamulira: dongosolo la batri lidzapereka chosinthira kapena chophwanyira, chochepa chomwe chiyenera kukhala 60V m'malo mwa 50V. Zofunikira zowonjezera pakuwongolera kwa fuse ya overcurrent.
Kusintha Maselo a 7.12 (mabatire ndi electrochemical capacitor): Kwa maselo a Li-ion omwe amatha kuchargeable, kuyesa pansi pa annex E kumafunika, popanda kuganizira UL 1642. Maselo amafunikanso kufufuzidwa ngati akwaniritsa zofunikira za mapangidwe otetezeka, monga zinthu ndi malo a insulator, kuphimba anode ndi cathode, etc.
