▍ CTUVus & ETL CERTIFICATION yog dab tsi?

OSHA (Occupational Safety and Health Administration), koom nrog US DOL (Department of Labor), xav kom txhua yam khoom siv hauv chaw ua haujlwm yuav tsum tau kuaj thiab ntawv pov thawj los ntawm NRTL ua ntej muag hauv khw. Cov qauv xeem siv tau suav nrog American National Standards Institute (ANSI) cov qauv; American Society for Testing Material (ASTM) cov qauv, Underwriter Laboratory (UL) cov qauv, thiab lub koom haum kev sib nrig sib lees paub cov qauv.

▍OSHA, NRTL, cTUVus, ETL thiab UL cov ntsiab lus txhais thiab kev sib raug zoo

OSHA:Abbreviation of Occupational Safety and Health Administration. Nws yog kev koom tes ntawm US DOL (Department of Labor).

NRTL:Abbreviation of Nationally Recognized Testing Laboratory. Nws yog tus saib xyuas ntawm lab kev lees paub. Txog tam sim no, muaj 18 lub koom haum thib peb uas tau pom zoo los ntawm NRTL, suav nrog TUV, ITS, MET thiab lwm yam.

cTUV:Daim ntawv pov thawj ntawm TUVRh hauv North America.

ETL:Abbreviation of American Electrical Testing Laboratory. Nws tau tsim nyob rau xyoo 1896 los ntawm Albert Einstein, tus neeg tsim khoom Asmeskas.

UL:Cov ntawv luv ntawm Underwriter Laboratories Inc.

▍ Qhov txawv ntawm cTUVus, ETL & UL

▍ Vim li cas MCM?

● Kev txhawb nqa muag los ntawm kev tsim nyog thiab thev naus laus zis:Raws li lub chaw kuaj neeg ua pov thawj ntawm TUVRH thiab ITS hauv North American Certification, MCM muaj peev xwm ua tau txhua yam kev sim thiab muab kev pabcuam zoo dua los ntawm kev sib pauv tshuab ntsej muag.

● Kev txhawb nqa nyuaj los ntawm kev siv tshuab:MCM tau nruab nrog tag nrho cov khoom siv ntsuas rau cov roj teeb ntawm qhov loj me, me me thiab cov haujlwm ua tau zoo (xws li lub tsheb fais fab, lub zog cia, thiab cov khoom siv hluav taws xob digital), muaj peev xwm muab tag nrho.roj teebCov kev pabcuam kuaj thiab ntawv pov thawj hauv North America, suav nrog cov qauv UL2580, UL1973, UL2271, UL1642, UL2054 thiab lwm yam.

Tshooj 4 ntawm cov lus pom zoo yuav muaj feem cuam tshuam rau lub roj teeb tsim: ib zaug kev hloov kho cov lus pom zoo ntawm kev ua txhaum ntawm cov khoom tiv thaiv thiab cov khoom siv hluav taws xob tau txais, thaum kev tiv thaiv tau ua los ntawm ob lub voj voog lossis cov khoom siv, lwm yam kev tiv thaiv yuav tsum tau ntxiv vim tias cov cov thawj yuav tsum tau faulted. Piv txwv li, nyob rau hauv qhov kev xeem overcharge, yog tias ob tug tib MOSFETs siv rau kev tiv thaiv overcharge
yuav tsum tau faulted yam tsis muaj lwm yam overcharge tiv thaiv designs ua hauj lwm, lub roj teeb poob lub overcharge tiv thaiv thiab kev ntsuam xyuas yog tsis yooj yim sua kom dhau.Nyob rau hauv cov ntsiab lus, nws yog pom zoo kom manufacturers txais ob txoj kev tiv thaiv sib txawv thaum tsim lub roj teeb los daws cov kev hloov tom ntej.
