Switching power supply kev ruaj ntseg ntawv pov thawj
Lub hwj chim hloov yog qhov tseem ceeb tshaj plaws txhua hnub, thiab nws qhov kev thov kuj tseem loj heev. Cov ntawv pov thawj sib txawv yog luam tawm ntawm cov ntawv cim ntawm kev hloov cov khoom siv hluav taws xob lossis lwm yam khoom. Nws tuaj yeem pom tias daim ntawv pov thawj tau nkag mus rau peb lub neej thiab tau muaj qee yam cuam tshuam. . Yog tias tau txais daim ntawv pov thawj, nws txhais tau tias cov khoom zoo ua tau raws li lub teb chaws lossis thoob ntiaj teb cov qauv.
Cov khoom pov thawj feem ntau rau kev hloov khoom siv hluav taws xob yog:
1. Tuam Tshoj CCC, CQC, Tuam Tshoj Zog Efficiency Label. 3C ntawv pov thawj yog cov khoom siv hluav taws xob ntau tshaj plaws hauv Suav teb, thiab nws lub npe lus Askiv yog Tuam Tshoj Compulsory Certification, uas yog "Tuam Tshoj Compulsory Product Certification". 3C daim ntawv pov thawj yog cov khoom lag luam kev ntsuas kev ua tau zoo los ntawm tsoomfwv Suav raws li kev cai lij choj thiab kev tswj hwm txhawm rau tiv thaiv cov neeg siv khoom kev nyab xeeb thiab kev nyab xeeb hauv tebchaws, ntxiv dag zog rau kev tswj xyuas cov khoom zoo. 3C ntawv pov thawj yog daim ntawv pov thawj kev nyab xeeb tshaj plaws, tsis yog cov khoom lag luam zoo. Cov neeg siv khoom tuaj yeem mus rau Tuam Tshoj Cov Ntawv Pov Thawj Zoo los nug txog cov chaw tsim khoom siv hluav taws xob los ntawm 3C daim ntawv pov thawj tus lej ntawm cov khoom siv hluav taws xob.
2. EU CE, ROHS, EuP cov lus qhia. CE los ntawm Fabkis "CommunateEuroppene", uas txhais tau tias European Union. CE kuj tseem yog daim ntawv pov thawj kev nyab xeeb. Peb tuaj yeem suav nws raws li European "3C" tus qauv. Cov khoom lag luam nrog cov cim CE tuaj yeem muag hauv EU cov tswvcuab lub xeev yam tsis tas yuav ua kom tau raws li cov cai ntawm txhua lub xeev cov tswvcuab. Txhawm rau kom paub qhov kev xa tawm dawb ntawm cov khoom, Tuam Tshoj cov khoom siv hluav taws xob hauv tsev feem ntau tau dhau daim ntawv pov thawj no. RoHS yog tus qauv yuav tsum tau tsim los ntawm EU txoj cai lij choj, thiab nws lub npe tag nrho yog "Kev txwv tsis pub muaj phom sij hauv cov khoom siv hluav taws xob thiab hluav taws xob". Tus qauv tau ua tiav thaum Lub Xya Hli 1, 2006, thiab feem ntau yog siv los tsim cov khoom siv thiab cov txheej txheem ntawm cov khoom siv hluav taws xob thiab hluav taws xob, ua kom muaj txiaj ntsig zoo rau tib neeg kev noj qab haus huv thiab kev tiv thaiv ib puag ncig. Lub hom phiaj ntawm tus qauv no yog txhawm rau tshem tawm 6 yam khoom xws li txhuas, mercury, cadmium, hexavalent chromium, polybrominated biphenyls thiab polybrominated diphenyl ethers hauv cov khoom siv hluav taws xob thiab hluav taws xob, thiab nws feem ntau hais tias cov ntsiab lus ntawm cov hlau lead yuav tsum tsis pub tshaj 0.1%. ROHS yog lub cim tseem ceeb ntawm kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig. Thaum yuav khoom siv hluav taws xob, koj yuav tsum ua tib zoo saib seb lub tshuab hluav taws xob puas tau dhau daim ntawv pov thawj no, txhawm rau kom muaj txiaj ntsig zoo rau koj tus kheej kev noj qab haus huv thiab txo cov pa phem ib puag ncig thaum nws muab pov tseg yav tom ntej.
3. American UL, ETL, FCC, CEC thiab Energy Star. Lub npe tag nrho ntawm UL yog Underwriter Laboratories Inc. (Underwriters Laboratories) yog lub koom haum soj ntsuam kev nyab xeeb uas tsis muaj txiaj ntsig tshaj plaws hauv Tebchaws Meskas. Nws tsuas yog ua cov kev ntsuam xyuas kev nyab xeeb thiab kev tshuaj xyuas ntawm ntau yam khoom siv, tshuab thiab cov ntaub ntawv kom paub meej tias puas muaj kev phom sij rau lub neej thiab khoom, thiab tshaj tawm cov txiaj ntsig tshuaj xyuas. UL tau tshaj tawm ntau pua tus qauv, feem ntau tau txais los ntawm ANSI (American National Standards Institute), thiab tam sim no UL ntawv pov thawj tau dhau los ua ib daim ntawv pov thawj nruj tshaj plaws hauv ntiaj teb. Feem ntau, UL cov qauv tuaj yeem muab faib ua: cov kev xav tau rau cov qauv khoom, cov kev xav tau rau cov khoom siv raw siv hauv cov khoom, cov kev xav tau rau cov khoom siv hauv cov khoom, cov kev cai rau kev ntsuas cov cuab yeej thiab cov qauv kev xeem, cov khoom siv rau cov cim thiab cov lus qhia, thiab lwm yam. UL daim ntawv pov thawj muaj ntau yam cim nyob ntawm seb qhov kev thov thiab thaj tsam ntawm daim ntawv thov. Koj tuaj yeem siv cov khoom siv hluav taws xob nrog hom ntawv pov thawj no nrog kev ntseeg siab.
4. Canadian CSA, CUL, IC.
5. Australia SAA, C-tick, MEPS.
6. Kaus Lim Kauslim KC, Mic-kos, Kauslim zog efficiency daim ntawv lo.
7. German GS, thoob ntiaj teb CB.
8. Kuwait KUCAS, Nigeria SONCAP, Saudi Arabia SASO.
9. Nyiv PSE, Philippines ICC, Kenya PVOC, Iran VOC.
Nyob rau hauv cov nqe lus ntawm cov tshuaj tiv thaiv ib puag ncig kuaj, ntxiv rau cov RoHS ib txwm, peb tseem tuaj yeem nqa tawm REACH, PAHs polycyclic aromatic hydrocarbons, POHS, CPSIA, California 65, LMBG, Phthalates, TBBP-A tetrabromobisphenol A, MSDS, azo AZO, Roj teeb. Cov Lus Qhia, Ntim Cov Lus Qhia, Halogen, PCB Polychlorinated Biphenyls, PVC Polyvinyl Chloride, thiab lwm yam.
