Yog tias koj tso koj lub teeb taws teeb lossis xov tooj cua nyob ib hmos, lub roj teeb hauv koj lub tsheb yuav luag tas. Kom them lub roj teeb tuag tom tsev, koj tuaj yeem yuav lossis teeb tsa lub tsheb siv roj tsheb.
Nws yog qhov tsim nyog
- - lub computer fais fab muab;
- - 25-volt tso zis capacitors;
- - txha hniav laus hlau d0, 5-0, 6 hli;
- - kev tawm tsam 2 W;
- - ammeter;
- - soldering hlau;
- - ham;
- - flux thiab soldering acid.
Cov Lus Qhia
Kauj ruam 1
Nqa lub computer fais fab mov TX lossis ATX, kuaj nws rau kev ua haujlwm. Tshem tawm sab saum toj ib nrab ntawm rooj plaub thiab pom daim txiag twg nws tau ua. Lub voj voog TL494CN (cov lus sib piv ntawm KA7500, DBL494, A494, IR3M02, mPC494C, MV3759, M1114EU, thiab lwm yam) tsim nyog rau peb.
Kauj ruam 2
Tshem tag nrho cov xov hluav taws xob tawm ntawm pawg thawj coj, tawm tsuas yog 2 daj (12 volts) thiab 2 xim dub (qhov no yog "COM", av). Cov cuab yeej hluav taws xob ATX chav ntsuas hluav taws xob tseem muaj lub xov hlau ntsuab coj los tso cai rau tig PS-ON, ham nws hauv av. Cov xov ntawm tus kiv cua thiab 220 volt network yuav tsum tsis txuas.
Kauj ruam 3
Tshem lub rooj tsavxwm los ntawm rooj plaub thiab hloov lub 16-volt tso zis electrolytic capacitors nrog 25-volt. Thov nco ntsoov tias koj yuav tsum tsis txhob txo qis ntawm tus neeg ntawm daim pib (koj tuaj yeem nce nws).
Kauj ruam 4
Saib ntawm cov ciav hlau ntawm thawj cov zis ntawm microcircuit, txiav tawm tag nrho cov ntsiab lus tsis tsim nyog (los ntawm kev txiav lossis nthuav tawm ntawm seem). Muab cov ntsuas hluav taws xob tsis sib xws rau cov teeb meem pem hauv ntej ntawm rooj plaub, nws yuav ua raws li cov khoom siv hluav taws xob tsim hluav taws xob (teeb tsa voltage ntawm 3 txog 24 volts). Yog tias koj npaj yuav siv cov cuab yeej tsuas yog siv lub roj teeb tsheb, koj tuaj yeem tsim qhov tsis hloov nrog qhov ntsuas ntawm 14.4 volts.
Kauj ruam 5
Tshem tawm txhua qhov tsis txuas sib txuas 2 thiab 3 pins ntawm microcircuit. Ntawm plaub ceg tawm, tso tawm cov kev tiv thaiv uas thaiv kev tshaj tawm ntawm cov pulses, tawm qhov "pib ua haujlwm" ua haujlwm, txiav txhua qhov tsis tsim nyog.
Kauj ruam 6
Ntawm qhov thib 15 thiab 16 pins, teeb tsa qhov kev txwv ntawm cov zis tam sim no kom thaum twg los ntawm qhov tsis kam tiv thaiv tam sim no tsis tshaj tus nqi thiab koj tsis ntshai ntawm kev luv luv. Ua li no, ua rau lub zog tam sim no nyob rau hauv txoj kev no: coj ob-watt tsis kam ntawm cov hom MLT, cua ib tus txha hniav laus xaim d0, 5-0.6 hli rau nws, hauv ib kab (tig mus rau sab hauv), thiab solder xaus rau cov terminals ua hauj. Hloov chaw ntawm lub ntsuas hluav taws xob tam sim no, koj tuaj yeem txhim kho ib qho kev ntsuas kom haum.
Kauj Ruam 7
Hloov cov kuj tsis paub meej nrog ib qho sib txawv los ntawm kev teeb tsa qhov siab tshaj plaws kev them nyiaj tam sim no. Yog tias koj npaj yuav them 60 amp-teev txhuas kua qaub roj teeb, teeb lub lub sijhawm them mus rau 6 amp.
