A DC connector (los yog DC plug, rau ib hom kev sib txuas) yog ib qho hluav taws xob txuas rau kev muab cov tam sim no ncaj qha ( DC ) lub zog rau lub teeb. Piv nrog rau cov khoom siv hluav taws xob hauv tsev AC fais fab thiab cov sockets, DC connectors muaj ntau ntau hom qauv uas tsis hloov pauv tau.

Xav txog qhov no, DC adapter txhais li cas?

Direct Tam sim no Adapters A DC adapter txawv ntawm AC adapter hauv qhov ntawd DC adapter converts AC hluav taws xob rau hauv DC hluav taws xob. Piv txwv li, 12 V DC adapter muag hauv Tebchaws Meskas yuav Hloov 120 V AC ntawm 60 Hz rau 12 V DC . Zoo li nws AC counterpart, a DC adapter tseem nyob rau qhov siab tshaj plaws lub zog tso zis hauv watts.

Dab tsi yog qhov zoo ntawm DC plug? Qhov chaw zoo daim duab ntawm sab laug qhia tias qhov chaw nruab nrab (ntsiab) ntawm cov zis ntsaws yog zoo (+) thiab lub thoob ntawm cov zis ntsaws yog negative (-). Symbol rau lub center- zoo fais fab mov. Outer Barrel yog qhov tsis zoo.

Ib yam li ntawd, nws raug nug, DC txhais li cas ntawm lub monitor?

DC -IN 19V (Hwj chim) - Nkag mus rau qhov txuas saib xyuas lub zog. Sab nraud fais fab mov, siv me me saib xyuas , qhov no yog ua nyob rau hauv thiaj li yuav txo lub thickness ntawm lub saib xyuas thiab ua kom cov khoom siv hluav taws xob hloov tau yooj yim thaum muaj kev ua haujlwm tsis zoo.

DC qhov chaw yog dab tsi?

DC qhov chaw xa mus rau qhov chaw ntawm hluav taws xob hluav taws xob uas cuam tshuam nrog qhov tsis tu ncua voltages thiab tam sim no. A DC fais fab mov tuaj yeem tsim ua hluav taws xob hluav taws xob ua haujlwm los ntawm cov khoom siv hluav taws xob ac thiab tsim rau lub hom phiaj.
