Zoo siab rau Weeyu tau txais daim ntawv pov thawj UL ntawm peb M3P series rau qib 2 32amp 7kw thiab 40amp 10kw tsev EV them chaw nres tsheb. Raws li thawj thiab tsuas yog cov chaw tsim khoom tau txais UL teev rau tag nrho cov charger tsis yog cov khoom siv los ntawm Tuam Tshoj, peb cov ntawv pov thawj suav nrog Asmeskas thiab Canada. Daim ntawv pov thawj tus lej E517810 tam sim no tau lees paub ntawm UL lub vev xaib.

Lawv lees paub cov khoom nrog lub hom phiaj ua kom lub ntiaj teb muaj kev nyab xeeb dua rau cov neeg ua haujlwm thiab cov neeg siv khoom. Dhau li ntawm kev sim, lawv tau teeb tsa cov qauv kev lag luam kom ua raws thaum tsim khoom tshiab. Xyoo tas los ib leeg, kwv yees li 14 billion cov khoom lag luam nrog UL foob nkag mus rau hauv kev lag luam thoob ntiaj teb.
Hauv kev txiav txim siab, UL yog lub koom haum kev nyab xeeb uas teeb tsa kev lag luam thoob plaws cov qauv ntawm cov khoom tshiab. Lawv txuas ntxiv xyuas cov khoom no kom ntseeg tau tias lawv ua raws li cov qauv no. UL kuaj xyuas kom paub tseeb tias qhov loj ntawm cov xaim yog qhov tseeb lossis cov khoom siv tuaj yeem tswj cov nqi tam sim no lawv thov kom muaj peev xwm. Lawv kuj xyuas kom meej tias cov khoom tsim tau raug tsim kom muaj kev nyab xeeb tshaj plaws.
Ib qho kev xav tsis zoo yog tias UL kuaj txhua yam khoom lawv tus kheej. Qhov no tsis yog ib txwm muaj. Hloov chaw, UL tso cai rau cov chaw tsim khoom los kuaj cov khoom lawv tus kheej siv UL stamp. Lawv mam li ua raws li niaj zaus kom paub tseeb tias lawv sim lawv cov khoom thiab ua raws li cov lus qhia kom raug. Qhov no yog ib qho ntawm ntau qhov laj thawj uas UL daim ntawv pov thawj txaus nyiam rau cov lag luam.
Yog li hauv paus UL yog daim ntawv pov thawj tshaj plaws ntawm kev nyab xeeb thiab kev ntsuas zoo hauv Teb Chaws Asmeskas Yog li yog tias cov khoom yog UL teev, nws txhais tau tias cov khoom muaj kev nyab xeeb thiab zoo, nrog rau cov neeg txaus siab muag nws thiab siv yam tsis muaj kev txhawj xeeb. Qhov ntawd yog lub logic.
Vim li cas UL daim ntawv pov thawj txaus nyiam rau kev lag luam? UL tau siv ntau tshaj ib puas xyoo los tsim lub koob npe nrov thiab txhawb kev ntseeg siab. Thaum tus neeg siv khoom pom UL daim ntawv pom zoo ntawm cov khoom, lawv yuav xav zoo dua txog kev yuav khoom.
Piv txwv li, yog hais tias ib tug neeg yuav khoom rau ib tug tshiab Circuit Court breaker los yog contactor, UL ntawv pov thawj yuav sway lawv qhov kev txiav txim.

Nws tau pom tias UL cim tuaj yeem yog lub cuab yeej ua lag luam muaj zog rau kev lag luam, thiab ntau ntawm lawv siv zog kom tau txais lawv cov khoom pom zoo. Lub logo UL muab cov neeg siv khoom sib haum xeeb ntawm lub siab, thiab kev lag luam muaj kev pom zoo rau pej xeem.
Thaum peb rub rov qab thiab saib yav dhau los ntawm kev lag luam, nws tau nkag siab tias cov tshuab yog lub neej ntawm kev lag luam. Ua cov kauj ruam los tiv thaiv qhov kev nqis peev no thiab cov neeg siv nws yog qhov tseem ceeb rau kev ua tiav ntev ntawm lub tuam txhab. Ntau qhov kev lag luam tau pib tsim cov khoom tshiab nyob ib puag ncig UL cov qauv kev nyab xeeb.
Yuav ua li cas cov lag luam thiab cov neeg siv khoom tau txais txiaj ntsig los ntawm kev xa tawm UL cov npe khoom?
1.Smooth kev lis kev cai clearance: nrog UL ntawv pov thawj, US kev lis kev cai tso tawm lub cargo sai heev, tab sis tsis muaj nws, tej zaum yuav ntev thiab dull tshuaj ntsuam.
2.Thaum muaj teeb meem kev nyab xeeb, CPSC yuav txiav txim lub luag haujlwm yog tias cov khoom muaj ntawv pov thawj UL, uas yuav pab kom tsis txhob muaj teeb meem tsim nyog thiab tsis sib haum xeeb yog li ntau tus neeg muag khoom tsuas yog muag cov khoom nrog UL ntawv pov thawj.
3.Nrog UL daim ntawv pov thawj ua rau muaj kev cia siab thiab kev ntseeg siab ntawm cov neeg siv khoom kawg los yuav cov khoom no thiab cov neeg muag khoom muag cov khoom no.
4.Nws pab kom nthuav kev muag khoom.
5.Qhov kev muag khoom yooj yim dua thiab sai dua.
Ev them nyiaj ua lag luam tsis yog tshiab tab sis twv yuav raug hu, nyob rau theem pib ntawm lub zog tshiab kev lag luam yog li ntau lub tuam txhab tab tom nrhiav rau hauv kev lag luam no yog tshiab rau kev lag luam, nyob rau hauv cov xwm txheej no, UL yuav pab tau koj.
