2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:29

Kuv twb tau ua ob peb PSU. Thaum pib kuv ib txwm xav tias kuv xav tau PSU nrog ntau Amps, tab sis nyob rau ob peb xyoos ntawm kev sim thiab tsim cov khoom Kuv pom tau tias kuv xav tau PSU me me nrog kev ruaj khov thiab zoo Voltage kev tswj thiab txwv tam sim no, uas tsis siv ntau qhov chaw ntawm kuv lub workbench.

Zoo li feem ntau ntawm kuv txoj haujlwm nws txhua qhov pib nrog khaws cov khoom uas tau los ntawm kuv tus tswv. Kuv tus phooj ywg tau muab kuv tus hloov pauv 230V/16V los ntawm lub tswb qub uas yog lub hauv paus tseem ceeb ntawm kuv li PSU.

Kauj Ruam 2: ATX Housing Adaptation - Hardware Work

Thaum kuv muaj txhua feem ntawm kuv txhais tes nws yog lub sijhawm rau kev tswj chaw hauv PSU. Vim tias kuv txiav txim siab siv ATX cov khoom siv hluav taws xob nyob hauv tsev Kuv yuav tsum tswj hwm txhua yam ua tib zoo thiab qhov kev npaj chaw no coj kuv sijhawm ntau.

Tom qab txhua yam tau txias, Kuv tau ua daim ntawv rau pem hauv ntej ntawm kuv lub PC kom yooj yim rau kos.

Feem ntau nws tsuas yog drilling, lub qhov rau ampere/volt-meter Kuv tau siv lub laum me me (tsis paub nws hu li cas)

Hauv qab ntawm lub tsev kuv tau teeb tsa plaub qhov sawv ntsug uas kuv tau rhuav tshem los ntawm cov kas fes qub

Kov rau sab nraub qaum yog los ntawm lub qhov (socket) chav ua noj qub, ntsia nrog ob lub txiv ntseej M4 nrog lub tshuab ntxhua khaub ncaws:)

Kauj ruam 3: Schematic

Nov yog cov txheej txheem ntawm PSU (Kuv tsis yog tus kws tshaj lij nrog kev kos duab ntawm cov txheej txheem, zoo li koj tuaj yeem pom). Yog tias qee yam tsis meej thov koj xav nug hauv cov lus, Kuv paub tias cov phiaj xwm tuaj yeem ua tau zoo dua thiab thaum kuv pom qee lub sijhawm kuv yuav rub tawm cov ntawv zoo dua.

Kuv ntxiv cov ntsuas cua sov rau qhib lub kiv cua, thaum kuv siv PSU ntawm qhov me me tam sim no lossis ntawm tos kuv tsis xav hnov kiv cua. Kuv tau teeb tsa transistor thiab ntsuas hluav taws xob ruaj khov IC (7812), ntawm qhov txias dua.

Kuv drilled qhov rau qhov ntsuas cua sov mus rau hauv lub txias.

Rau kev teeb tsa lub kiv cua ntawm lub tshuab txias kuv siv 1.5 hli tooj liab xaim thiab txhawm rau kho lub kiv cua thiab txias dua mus rau lub tsev kuv tau siv plaub 1cm kev sawv ntsug.

Cov tiv thaiv rau cov LEDs tau muag ncaj qha rau ntawm 3mm LED thiab tom qab ntawd cais nrog cov raj nqaim.

Lub hauv paus ntsiab lus zoo ib yam yog siv rau kev txuas cov neeg sib txuas

Kauj Ruam 4: Carbon Fiber Vinyl Wrap

Kuv xav ua kom zoo saib rau lub tsev, yog li kuv siv Carbon Fiber Vinyl Wrap tsis txhob pleev xim. Kuv kuj tau txais lub tswv yim uas kuv tuaj yeem kho PSU nrog kuv kos npe:), Kuv tau txiav kuv lub cim cim ntawm lub thawv ntawv thiab npog nws nrog cov yas qhwv, kuj kuv tsis xav muaj qhov tsis tsim nyog ntawm lub tsev yog li kuv siv thawv lub thawv los ntawm qhov kuv nyiam ncuav qab zib thiab npog lub qhov thiab tseem npog nrog cov yas yas

Kauj Ruam 5: Pem Hauv Ntej thiab Tom Qab

Kuv xav kom muaj lub vaj huam sib luag pem hauv ntej zoo, yog li kuv tau tsim lub vaj huam sib luag pem hauv ntej ntawm kuv lub khoos phis tawj (siv qhov program twg uas koj nyiam) thiab luam tawm ntawm lub tshuab luam ntawv. Qhov no yooj yim heev kuj rau kho vajtse ib feem ntawm kev drilling thiab txiav. Pem hauv ntej ntawm daim ntawv nplaum kuv tau txwv nrog daim kab xev pom. Sab nraum qab ntawm daim ntawv nplaum yog txwv tsis pub muaj ob kab xev thiab kaw rau ntawm lub tsev.

Kauj Ruam 6: Txhim Kho Cov Txheej Txheem ntawm Pem Hauv Ntej Vaj Huam Sib Luag thiab Hauv Vaj Tsev

Thaum cov vaj tse tau npaj kuv tau pib nrog kev teeb tsa cov khoom ntawm/hauv nws. Vaj tsev muaj ob ntu, yog li kom yooj yim sib dhos yuav tsum muaj cov xov hlau ntev txaus rau kev ua haujlwm thaum sib dhos.

Cov av nyob hauv tsev yog qhov tseem ceeb heev, ATX feem ntau muaj qhov chaw txuas hauv av hauv tsev, txheeb xyuas nws ntawm cov duab

Ua ntej kuv tau teeb tsa txhua yam hauv vaj tsev thiab pib thaiv txhua yam ua ke raws li cov phiaj xwm. Txhua qhov kev sib cuag tau zoo soldered tsim kom muaj kev sib cuag tau zoo thiab txhim khu kev qha thiab cais tawm nrog cov raj nqaim.

Kauj Ruam 7: Kev ntsuas thiab ntsuas qhov ntsuas sov

Amper/Volt meter muaj lub zog me me (me me) nyob tom qab ntawm lub ntsuas vaj huam sib luag, siv rau kev ntsuas ntsuas.

Tom qab thaiv txhua yam txhua qhov ua ke ntsuas qhov ntsuas hluav taws xob thiab ampere meter yog qhov tsim nyog. Nrog Volt meter yog qhov yooj yim thiab raug, kuv tau qis qhov hluav taws xob mus rau 4.5V thiab siv lub zog ntsuas hluav taws xob nyob tom qab ntawm voltmeter los teeb nws nrog kuv lub ntsuas cua, kuv rov hais dua qhov no ntawm 12V thiab 13.7V.

Kev ntsuas ntsuas ntawm Ampere meter yog qhov nyuaj me ntsis, Kuv tau suav tam sim no rau 5W teeb P = U*I, yog li tam sim no yuav tsum yog ntawm 12V I = 5 /12 = 0.416A. Qhov no tsis yog thawj chav ampermeter tab sis kuv tswj kom teeb tsa nws nyob ze rau qhov xav tau tshaj plaws, Kuv rov ua cov kauj ruam no nrog 15W thiab 21W teeb thiab tswj kom ntsuas kom ze rau qhov tseem ceeb tshaj plaws, thiab sib piv qhov no nrog kuv lub multimeter thiab nws yog qhov tseeb txaus rau ib txwm thiab siv tau zoo Tsis txhob cia siab tias lab PSU yog qhov tseem ceeb….

Cov ntsuas cua sov tau teeb tsa kom qhib lub kiv cua ntawm 40 C °, teeb tsa lub ntsuas cua sov tsis yog qhov nyuaj heev thiab cov lus qhia raug nyob ntawm qhov chaw uas kuv yuav lub ntsuas sov. Tom qab ob lub hlis ntawm kev siv ua haujlwm tau zoo.

Kauj Ruam 8: Kev Sib Txuas Cable rau Weller Soldering Station

Kuv muaj TCP-S Weller soldering chaw nres tsheb uas muaj 50W /24VAC hloov pauv uas zoo tshaj rau kuv PSU. Los ntawm tus qub Weller tuav Kuv tau sau cov khoom sib txuas thiab ua txuas txuas txuas txuas txuas haum rau kuv PSU yog tias kuv xav tau ntau Voltage thiab kua txiv.

Raws li koj tuaj yeem pom ntawm cov txheej txheem, rau lub hom phiaj no kuv tau ntxiv 24VAC txuas ntawm cov tswv yim, thaum lwm qhov chaw ntxiv PSU cia li hloov mus rau cov lus qhia no yog lub cim nrog xiav LED ntawm lub vaj huam sib luag.

Kauj Ruam 9: Cov Khoom Kawg

Nws yog PSU zoo nrog qhov me me, nws ua haujlwm tau zoo thiab kuv zoo siab nrog nws. Ib qho lus pom thiab txhim kho tau txais tos.
