Yuav ua li cas kom 12 volt dc fais fab mov tsis muaj transformer
Yog tias koj tsis muaj lub tshuab hloov pauv, koj tuaj yeem sim ua ib qho 12-volt DC fais fab mov siv cov hauv qab no:
1. Resistor-capacitor kauj ruam-down Circuit Court: qhov no yog ib txoj hauv kev yooj yim thiab tus nqi qis, tshwj xeeb tshaj yog tsim nyog rau lub sijhawm uas tsis tshua muaj hluav taws xob, xws li kev siv hluav taws xob rau qee qhov ICs lossis cov qauv ntsuas thiab ntsuas cov lus tawm tswv yim tam sim no. Qhov no Circuit Court siv ib tug ua ke ntawm capacitors thiab resistors los txo qhov voltage. Koj yuav tsum xaiv cov capacitors thiab cov resistors tsim nyog los ua kom muaj qhov hluav taws xob tawm ntawm li 12 volts. Nco ntsoov, txawm li cas los xij, tias qhov tso zis voltage ruaj khov ntawm qhov Circuit Court no kuj tsis zoo thiab muaj teeb meem nrog overvoltage thiab tiv thaiv overcurrent.
2. Siv Rectifier thiab Filter Capacitor: Hloov 220 volts AC mus rau pulsating DC los ntawm lub rectifier thiab ces du cov zis siv lub lim capacitor. Txoj kev no muab qhov hluav taws xob DC smoother, tab sis yuav tsum tau txo qis ntxiv kom tau txais 12 volts DC. Koj tuaj yeem txiav txim siab ntxiv cov kauj ruam-down Circuit Court tom qab kho thiab lim, xws li siv cov resistors lossis voltage regulator diodes, txhawm rau txo qhov voltage mus rau 12 volts.
3. Siv lub tshuab hluav taws xob sib xyaw ua ke: Lub tshuab hluav taws xob sib xyaw ua ke yog lub tshuab hluav taws xob hluav taws xob uas tau hloov kho qhov tso zis hluav taws xob. Koj tuaj yeem xaiv qhov sib xyaw ua ke hluav taws xob tswj hluav taws xob nrog cov khoom siv hluav taws xob ntau ntawm 220 volts thiab cov zis hluav taws xob ntawm 12 volts thiab txuas mus rau lub zog hluav taws xob. Qhov kom zoo dua ntawm txoj kev no yog tias qhov tso zis hluav taws xob yog qhov ruaj khov, tab sis nws yuav tsum muaj qee qhov kev paub txog kev siv hluav taws xob los xaiv thiab txuas cov kev tswj hwm kev sib koom ua ke.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias txoj kev twg koj xaiv, koj yuav tsum ua kom muaj kev nyab xeeb ntawm lub voj voog. Thaum lub sijhawm ua haujlwm, yuav tsum tau saib xyuas kom tsis txhob muaj xwm txheej txaus ntshai xws li hluav taws xob poob siab thiab luv luv Circuit Court. Nyob rau tib lub sijhawm, cov khoom siv hluav taws xob tsim yuav tsum ua raws li cov qauv hluav taws xob cuam tshuam los xyuas kom meej tias nws muaj kev nyab xeeb rau kev siv.
Tsis tas li ntawd, yog tias koj daim ntawv thov yuav tsum muaj lub zog siab dua lossis muaj qhov tso zis ntau dua, nws raug nquahu kom xav txog kev siv lub tshuab hluav taws xob tshaj lij lossis kev yuav khoom npaj ua DC fais fab mov los xyuas kom muaj kev ruaj ntseg thiab kev ntseeg siab ntawm cov khoom siv hluav taws xob.
