UL Daim Ntawv Dawb, UPS vs ESS Status ntawm North American cov cai thiab cov qauv rauUPS thiab ESS,
UPS thiab ESS,
▍ 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 tsis zoo |
| Tsawg hom kev lees paub ntau dua li ntawm UL | Kev lees paub tsawg dua li ntawm UL hauv kev lees paub ntawm cov khoom lag luam |
▍ 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-loj, 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 cov roj teeb kuaj thiab ntawv pov thawj cov kev pabcuam hauv North America, npog cov qauv. UL2580, UL1973, UL2271, UL1642, UL2054 thiab lwm yam.
Uninterruptible power supply (UPS) technologies tau siv nyob rau hauv ntau yam kev siv rau ntau xyoo los pab txhawb kev ua haujlwm txuas ntxiv ntawm cov khoom tseem ceeb thaum lub sij hawm cuam tshuam ntawm lub zog ntawm daim phiaj. Cov tshuab no tau siv nyob rau hauv ntau qhov chaw sib txawv los muab kev tiv thaiv ntxiv los ntawm cov kab sib chaws cuam tshuam cuam tshuam nrog kev ua haujlwm ntawm cov khoom thauj. UPS systems feem ntau siv los tiv thaiv cov khoos phis tawj, khoos phis tawj thiab cov khoom siv sib txuas lus. Nrog rau kev hloov pauv tsis ntev los no ntawm cov thev naus laus zis tshiab, lub zog khaws cia (ESS) tau nthuav dav sai. ESS, tshwj xeeb tshaj yog cov uas siv roj teeb thev naus laus zis, feem ntau yog muab los ntawm cov khoom siv txuas ntxiv dua tshiab xws li hnub ci lossis cua zog thiab ua kom lub zog khaws cia los ntawm cov peev txheej no siv sijhawm sib txawv.
Tam sim no US ANSI tus qauv rau UPS yog UL 1778, Tus Qauv rau Cov Hluav Taws Xob Hluav Taws Xob. thiab CSA-C22.2 No. 107.3 rau Canada. UL 9540, Tus Qauv rau Kev Siv Hluav Taws Xob thiab Khoom Siv Hluav Taws Xob, yog Asmeskas thiab Canadian lub teb chaws tus qauv rau ESS. Txawm hais tias ob qho tib si UPS cov khoom lag luam paub tab thiab kev hloov pauv sai sai ntawm ESS tsim muaj qee qhov sib xws hauv kev daws teeb meem, kev ua haujlwm thiab kev teeb tsa, muaj qhov sib txawv tseem ceeb. Daim ntawv no yuav tshuaj xyuas qhov sib txawv tseem ceeb, piav qhia txog cov khoom siv kev nyab xeeb uas cuam tshuam nrog txhua tus thiab sau cov lej yuav hloov pauv li cas hauv kev hais txog ob hom kev teeb tsa.
UPS system yog ib qho hluav taws xob uas tsim los muab kev hloov pauv tam sim no-raws li lub zog ib ntus rau cov khoom tseem ceeb thaum muaj hluav taws xob tsis ua hauj lwm lossis lwm yam khoom siv hluav taws xob tsis ua haujlwm. UPS yog qhov loj los muab qhov txuas ntxiv tam sim ntawm lub zog uas tau txiav txim siab ua ntej rau lub sijhawm tshwj xeeb. Qhov no tso cai rau lub zog thib ob, piv txwv li, lub tshuab hluav taws xob, tuaj online thiab txuas ntxiv nrog lub zog thaub qab. UPS tuaj yeem kaw cov khoom tsis tseem ceeb thaum txuas ntxiv muab lub zog rau cov khoom siv tseem ceeb dua. UPS cov tshuab tau muab cov kev pabcuam tseem ceeb no rau ntau daim ntawv thov rau ntau xyoo. Lub UPS yuav siv lub zog khaws cia los ntawm qhov chaw siv hluav taws xob sib xyaw. Qhov no feem ntau yog lub txhab nyiaj roj teeb, supercapacitor lossis lub tshuab txav ntawm lub flywheel ua lub zog.
Ib tug raug UPS siv lub txhab nyiaj roj teeb rau nws cov khoom muaj xws li cov hauv qab no lub ntsiab Cheebtsam:
