Qhov txawv ntawm dc fais fab mov thiab ac fais fab mov
Aug 09, 2018| Noj 12V dc fais fab mov thiab 12V ac fais fab mov raws li piv txwv, qhov sib txawv ntawm dc thiab ac fais fab mov yog txheeb xyuas los ntawm cov khoom poob, kev siv, kev ntsuas thiab kev nyab xeeb.
Direct tam sim no tsis haum rau kev sib kis mus ntev vim nws qhov kev sib kis loj heev.
Hloov tam sim no muaj kev sib kis tsis zoo, yog li nws tsim nyog rau kev sib kis mus ntev
Lub dc voltage yog ruaj khov thiab tsis muaj suab nrov dawb. Yog li ntawd, nws yog qhov tsim nyog rau kev siv cov khoom siv hluav taws xob (xws li TV teeb, xov tooj cua thiab computer, thiab lwm yam).
Hloov tam sim no (ac) hloov mus rau tam sim no ncaj qha (dc) los ntawm kev hloov kho / hloov hluav taws xob (switching fais fab mov) siv rau hauv cov khoom siv hluav taws xob
Qhov sib txawv ntawm kev ntsuas ntawm 12V ac / dc:
Ntsuas nrog cov multimeter, ntsuas nrog 20V ac voltage thiab 20V dc voltage cov ntaub ntawv feem, qhov tshwm sim yuav txawv, yooj yim ntsuas txoj kev: siv induction mem hluav (tsis yog ib txwm hluav taws xob cwj mem) sab nraum cov hlau sheath, 12V ac tseem yuav pom tseeb tam sim no thiab tsis pom kev nyab xeeb
12V ncaj qha tam sim no muaj kev nyab xeeb dua li 12V alternating tam sim no. Thaum lub cev tsis kam ntawm tib neeg lub cev raug txo, 12V alternating tam sim no tseem tuaj yeem cuam tshuam cov neeg tuag, thaum 12V ncaj qha tam sim no tsis tuaj yeem cuam tshuam cov neeg tuag hauv 100% rooj plaub.
