Step-up cable yog dab tsi?

Boosterkabyog ib hom hlau uas ua rau kom cov zis voltage.Nws lub ntsiab tseem ceeb muaj nuj nqi yog hloov tsis tshua muaj hluav taws xob USB chaw nres nkoj inputs rau 9V / 12V DC outputs kom tau raws li qhov yuav tsum tau ntawm tej yam khoom siv uas yuav tsum tau 9V / 12V voltage fais fab mov.Txoj haujlwm ntawm txoj kab txhawb nqa yog muab cov khoom siv ruaj khov thiab txhim khu kev qha rau cov khoom siv hluav taws xob tsawg uas xav tau 9V 12V voltage, ua rau lawv ua haujlwm ib txwm.

Muaj qhov sib txawv tseem ceeb hauv kev ua haujlwm ntawm cov kab txhawb nqa thiab cov ntaub ntawv kab.Cov ntaub ntawv cables feem ntau yog siv rau kev xa cov ntaub ntawv thiab cov ntaub ntawv, tsis muaj kev hloov pauv voltage.Nws feem ntau yog siv los hloov cov ntaub ntawv, suab, video, thiab lwm yam ntaub ntawv ntawm cov khoom siv hluav taws xob.Cov ntaub ntawv cables raug cuam tshuam los ntawm cov teeb liab cuam tshuam thaum kis tau tus mob, yog li yuav tsum muaj qee qhov kev siv los ua kom ntseeg tau ntawm cov ntaub ntawv xa mus.Thiab cov kab boost tsom rau kev hloov pauv hluav taws xob los muab cov khoom siv hluav taws xob siab, xws li routers thiab optical modem, uas tsis cuam tshuam nrog cov ntaub ntawv xa mus.

Lub luag haujlwm ntawmnce kab yog qhov dav thiab tseem ceeb heev.Ntau yam khoom siv, xws li feem ntau cov routers, optical miv, FM xov tooj cua, lossis lwm yam khoom siv me me, yuav tsum muaj qhov hluav taws xob ntawm 9V lossis 12V kom ua haujlwm tau zoo.Cov kab txhawb nqa muab qhov yuav tsum tau muaj hluav taws xob los ntawm kev hloov pauv sab hauv ntawm PCB pawg thawj coj saib, ua kom cov haujlwm ruaj khov ntawm cov khoom siv no thiab tiv thaiv kev ua haujlwm tsis zoo lossis tsis ua haujlwm los ntawm qhov tsis txaus voltage.Tsis tas li ntawd, hauv qee qhov kev siv, lub boost cable kuj tseem tuaj yeem txuas nrog lub xov tooj ntawm tes them lub taub hau kom them lwm yam khoom siv hluav taws xob tsawg, xws li Bluetooth hais lus, cov khoom ua si me me, thiab xov tooj cua.

Hauv luv, ib qho kev txhawb nqakabyog ib hom hlau siv rau kev hloov hluav taws xob, nws lub luag haujlwm tseem ceeb yog hloov cov khoom siv hluav taws xob tsawg rau hauv cov zis hluav taws xob siab.Nws txoj haujlwm yog muab cov khoom siv hluav taws xob ruaj khov rau cov khoom siv uas yuav tsum muaj qhov tshwj xeeb voltage (tsawg dua 20V) kom ntseeg tau tias cov khoom siv ua haujlwm ib txwm muaj.Hauv qhov sib piv, cov ntaub ntawv cables yog cov cables siv rau kev xa cov ntaub ntawv thiab cov ntaub ntawv, uas muaj qhov sib txawv tseem ceeb hauv kev ua haujlwm thiab daim ntawv thov piv rau boost cables.Hom kab txhawb zog no tuaj yeem muab lub zog xwm txheej ceev rau koj lub router thaum muaj hluav taws xob poob.
