UL 1973:2022 magadzirirwo makuru
UL 1973:2022kuchinja kukuru,
UL 1973:2022,
▍ Chii chinonzi cTUVus & ETL CERTIFICATION?
OSHA (Occupational Safety and Health Administration), yakabatana neUS DOL (Department of Labor), inoda kuti zvigadzirwa zvese zvinofanirwa kushandiswa munzvimbo yebasa zviongororwe nekupihwa zvitupa neNRTL zvisati zvatengeswa pamusika. Miyero yekuyedza inoshanda inosanganisira American National Standards Institute (ANSI) zviyero; American Society for Testing Material (ASTM) zviyero, Underwriter Laboratory (UL) zviyero, uye fekitori mutual-recognition sangano zviyero.
▍OSHA, NRTL, cTUVus, ETL uye UL tsananguro yematemu nehukama
OSHA:Kupfupisa kweOccupational Safety uye Health Administration. Iyo mubatanidzwa weUS DOL (Dhipatimendi reVashandi).
NRTL:Kupfupisa kweNationally Recognized Testing Laboratory. Ndiyo inotarisira kubvumidzwa kwe lab. Kusvika parizvino, kune gumi nemasere echitatu-bato rekuyedza masangano akabvumidzwa neNRTL, kusanganisira TUV, ITS, MET zvichingodaro.
cTUVus:Certification chiratidzo cheTUVRh muNorth America.
ETL:Kupfupisa kweAmerican Electrical Testing Laboratory. Yakavambwa muna 1896 naAlbert Einstein, muvambi weAmerica.
UL:Nhoroondo ye Underwriter Laboratories, Inc.
▍Musiyano pakati pecTUVus, ETL & UL
| Item | UL | cTUVus | ETL |
| Kushandiswa mwero | Same | ||
| Institution inokwanisa kuwana risiti yechitupa | NRTL (rabhoritari yakabvumidzwa nenyika) | ||
| Applied market | North America (US neCanada) | ||
| Testing uye certification institution | Underwriter Laboratory (China) Inc inoita bvunzo uye inoburitsa tsamba yekupedzisa chirongwa | MCM inoita bvunzo uye TUV nyaya chitupa | MCM inoita bvunzo uye TUV nyaya chitupa |
| Kutungamira nguva | 5-12W | 2-3W | 2-3W |

▍ Neiko MCM?
● Tsigiro yakapfava kubva kuhunyanzvi uye tekinoroji:Seyapupu yekuyedza lab yeTUVRH neITS muNorth America Certification, MCM inokwanisa kuita marudzi ese ekuyedza uye nekupa sevhisi iri nani nekuchinjana tekinoroji chiso nechiso.
● Tsigiro yakaoma kubva kune tekinoroji:MCM inoshongedzerwa nemidziyo yese yekuyedza mabhatiri ehukuru-hukuru, diki-hukuru uye chaiyo mapurojekiti (kureva yemagetsi nharembozha, simba rekuchengetera, uye zvemagetsi zvigadzirwa zvedhijitari), inokwanisa kupa bhatiri rese rekuyedza uye masevhisi etifiketi muNorth America, inovhara zviyero. UL2580, UL1973, UL2271, UL1642, UL2054 zvichingodaro.
UL 1973:2022yakabudiswa musi wa25 Kukadzi. Iyi vhezheni yakavakirwa pamazano maviri ekunyorwa akapihwa muna Chivabvu naGumiguru we2021. Iyo yakagadziridzwa mwero inowedzera huwandu hwayo, kusanganisira mota mubatsiri simba system (semuenzaniso kuvhenekera nekutaurirana).
Append 7.7 Transformer: transformer yebhatiri system ichapihwa chitupa pasi peUL 1562 uye UL 1310 kana mazinga akakodzera. Low voltage inogona kupihwa chitupa pasi pe26.6.
Kwidziridzo 7.9: Dziviriro Denderedzwa uye Kudzora: bhatiri system ichapa switch kana breaker, iyo shoma inodiwa kuve 60V pachinzvimbo che50V. Kuwedzera kunodiwa pakuraira kweiyo overcurrent fuse.
Gadziridza 7.12 Masero (mabhatiri uye electrochemical capacitor): Kune rechargeable Li-ion masero, bvunzo pasi peannex E inodiwa, pasina kufunga nezve UL 1642. Masero anodiwawo kuti aongororwe kana achizadzisa kudiwa kwekugadzirwa kwakachengeteka, sechinhu uye chinzvimbo che insulator, kufukidzwa kweanode uye cathode, nezvimwe.
Append 16 High Rate Charge: Ongorora kuchengetedzwa kwekuchaja kwebhatiri system ine yakawandisa yekuchaja ikozvino. Inoda kuyedza mu120% yehuwandu hwekuchaja.
Append 17 Short Circuit Test: Ita mapfupi dunhu bvunzo yemamodule ebhatiri anoda kuisirwa mafaira kana shanduko.
