Qhov tseeb no tuaj yeem siv los them txhua lub roj teeb uas koj xav tau tam sim no thiab qhov hluav taws xob tas li.

Hauv cov lus qhia no kuv yuav coj koj mus dhau tag nrho cov txheej txheem los tsim cov kab ke kaw zaum kawg. Nws yuav siv cov tswv yim los ntawm ib qho AC/DC adapter nrog lub jack. Koj tsuas yog yuav tsum paub tseeb tias tus adapter tau ntsuas rau qhov hluav taws xob thiab tam sim no koj xav tsim. Cov kab ke no yuav tso cai txog 36V thiab 2Amps.

Kauj Ruam 1: Cov Cheeb Tsam & Cov Cuab Yeej Xav Tau

Cov khoom xav tau yog: Project Box, 220nF capacitor, 100nF capacitor, xaiv cov resistors nruab nrab ntawm 1and 5 Ohms, 5K/10K potentiometer, 820 Ohm resistorWiring - qee qhov dhia ua (haum rau txuas qhov txuas ntawm Circuit board ua ke), qee qhov cable nrog ob lub zog nqa ua rau sab hauv (pos + neg) GrommettCrocodile/Spade clips2.1mm lossis 2.5mm input jack (nyob ntawm koj lub zog qhov chaw) Cov tooj liab tooj liab L200CHeatsinkTxhua lub voj voos ncig L200C tam sim no/qhov ntsuas hluav taws xob (daim duab qhia chaw peb yuav ua raws nrog hauv qab no). Koj tuaj yeem rub cov ntaub ntawv los ntawm HERETools xav tau yogSoldering IronScrewdriver (Philips) thiab lub taub hau me me me

Kauj ruam 2: Lub thawv

Lub phiaj xwm phiaj xwm yog tsim los ntawm ABS yas, yog tias koj npaj yuav siv lub nti rau nws lub peev xwm tag nrho koj yuav xav tau lub thawv hlau. Qhov no yuav piav me ntsis tom qab. Nws yuav tsum yog qhov loj txaus kom tso rau hauv koj daim ntawv tooj liab thiab tseem muaj qee lub hauv paus rau L200C nti - cov nti no tuaj yeem tsim hluav taws kub thiab tshwj tsis yog lub thawv yog hlau koj tsis xav kom nws nias tawm tsam lub thawv.

Koj tuaj yeem pom tias lub qhov tau raug laum rau hauv lub thawv kom haum nrog DC Input jack. Yog tias koj saib ntawm DC cov tswv yim koj yuav pom tias nws muaj 3 tabs. Ib qho txuas rau hauv nruab nrab yog qhov zoo, qhov txuas ntxiv mus yog qhov tsis zoo - cov no tsuas yog ob peb peb nyiam. xyuas. (Kuv txawm hu xov xwm tseem ceeb ib puag ncig hauv liab)

Kauj Ruam 3: Thawj Yam Ua Ntej

Txheeb xyuas tias daim kab xev tooj liab haum rau hauv koj lub thawv, tej zaum koj yuav tsum tau txiav nws - Kuv tau tsim lub Circuit Court yog li nws yuav haum lub rooj tsavxwm nrog 23 qhov thiab 9 kab ntawv. Ib lub qhov twg los qhov kawg tsis siv los tso cai rau nws mus rau hauv lub qhov uas tau muab los ntawm qhov phiaj xwm phiaj xwm. Qhov zoo tshaj plaws kom ntseeg tau tias haum tam sim no ua ntej koj pib siv cov laug.

Koj kuj tseem yuav tsum tau tho qhov 2 nyob rau lwm qhov kawg ntawm lub thawv. Cov xaim dub uas muaj koj lub ntsiab ob txoj kab hluav taws xob tso tawm yuav tsum haum los ntawm cov yas grommit. Laum lub qhov, teeb tsa grommit thiab tshawb xyuas kab ntawv hla mus - nws yuav tsum yog qhov nruj kom koj lub xovtooj tsis rub tawm thiab ua rau lub rooj sibtham curcuit.

Kauj Ruam 4: Kuv Yuav Siv Qhov Voltage/Tam Sim No Li Cas?

Koj yuav tsum them koj cov roj teeb kua qaub raws li qhov tshwj xeeb ntawm cov chaw tsim khoom. Hauv qab no koj tuaj yeem pom qhov uas kuv tau them - 6.5volts ntawm.7Amps. Ua kom koj nyob ib ncig ntawm cov roj teeb uas koj xav tau kom them.

Kauj ruam 5: Circuit Court

Kuv suav nrog ob qhov hloov pauv ntawm daim phiaj xwm hluav taws xob, Koj muaj daim duab kab ke ib txwm muaj thiab cov duab sawv cev ntawm cov tooj liab tooj liab. C1 yog 220nF capacitorC2 yog 100nF capacitor Ob lub capacitors pab ua kom du thiab lim cov tswv yim thiab cov hluav taws xob tso tawm. R2 yog 820 Ohm Resisitor. W1 txog rau W6 yog txhua lub xov hlau txuas ntawm ntau qhov ntev. Cov khw muag khoom siv hluav taws xob feem ntau muaj lawv nyob. X cim koj pom ntawm cov ciav hlau tawg hauv cov kab tooj liab. Koj tuaj yeem tsoo lawv siv cov kab hluav taws xob rhuav tshem cov cuab yeej - tus neeg muag khoom kuv siv rau lawv tuaj yeem nrhiav tau ntawm Cov Hluav Taws Xob Hauv OnlineR1 yog 5K lossis 10K potentiometer. Daim ntawv ceeb toom tias lawv tau teeb tsa ua ntu zus. Qhov no yog siv 0.25W muaj peev xwm tiv taus ua rau tag nrho ntawm 0.75W. Tam sim no hla ncaj qha los ntawm cov resistors no nws yuav tsum tau ntsuas kom raug. Peb yuav tham txog qhov sib npaug rau xam qhov tseeb raug qhov tseeb sai kawg koj tuaj yeem pom L200C. Nws muaj tus lej lej uas koj tuaj yeem sib phim los ntawm cov ntawv teev npe. Koj yuav tsum ua qhov me me ntawm kev khoov maj mam kom tau cov kab pins raws li kuv muaj lawv - tu siab cov pins tsuas yog me ntsis nyob ze ua ke kom haum txig rau hauv pawg thawj coj saib. Pin 1 lees txais lees txais qhov ua tau zoo los ntawm lub zog. Pin 3 yog av (tsis zoo). Pin 5 yog cov zis. Pin 2 thiab Pin 4 tau siv los txiav txim qhov tseeb qhov hluav taws xob thiab tam sim no. Equations! R3 = 0.45 / Amps Yog li hauv kuv qhov xwm txheej kuv xav kom nws txwv qhov tam sim no rau 700mAR3 = 0.45 / 0.7 = 0.64 Ohms Hauv kuv kis kuv siv 3 qhov sib txawv sib txawv kom tau txais ze rau tus nqi ntawd - 1, 2.5 thiab 5 Ohms. Txoj hauv kev los suav cov resistors hauv kev sib luag yog 1/((1/R1) + (1/R2) + (1/R3)) hauv kuv cov ntaub ntawv uas yog 1/((1/1) + (1/2.5) + (1/ 5)) = 1 / (1 + 0.4 + 0.2) = 1 / 1.6 = 0.625 Ohms Qhov twg ze txaus! Txhawm rau ua haujlwm tam sim no koj tau txais los ntawm teeb tsa Ohm tus nqi koj tuaj yeem thim rov qab - nws muaj txiaj ntsig zoo los nrhiav seb koj kwv yees li cas nrog cov neeg tawm tsam tau txais koj. Tam sim no = 0.45 / 0.625 Ohms = 0.72Amps Lub zog dhau los ntawm R3 yog 0.45*0.45 / R3 hauv Ohms Hauv kuv qhov xwm txheej no yog 0.45 *0.45 / 0.625 = 0.324W, txiav txim siab 3 resistors tso cai rau tag nrho 0.75W peb ua tau zoo hauv kev ua siab ntev. Ua haujlwm tawm tus nqi ntawm R1 tau yooj yim. R1 = (Vout / 2.77 - 1) * R2 Peb paub tias R2 yog 820 Ohms thiab peb paub tias peb xav tawm VOut li cas (hauv kuv cov ntaub ntawv) R1 = ((6.5V/2.77) - 1) * 820 = 1104 Ohms Tom qab ntawd kho lub hwj chim qhov tseem ceeb 1) koj cov Volts IN xav tau txog 2Volts siab dua qhov koj xav tau Volts tawm. 2) Cov nti hlawv ntawm qhov hluav taws xob ntau/tam sim no raws li cua sov. Txhawm rau ua kom cua sov qis kom tsis txhob muaj VIN ntau dua li VOut - suav nrog tus lej 1. To ua haujlwm Watts tau tawg los ntawm cov nti koj yuav tsum tau ua (Vin -Vout) * xaiv tam sim no. Kuv qhov version yog 12V-6.5V * 0.7 = 3.85W. Kuv kuj tseem tau kaw lub rhaub dej kub rau kuv lub nti thiab lub thawv TSIS sov heev - txawm hais tias nws zoo li muaj peev xwm daws tau nws. Tej yam yuav ua rau nyuaj heev yog tias Vin yog 24V thiab Vout yog 6V thiab koj nyob ntawm 2A tam sim no tag nrho…. zoo nkauj kub ntawm 36W.. QHOV TSEEB lol

Kauj Ruam 6: Tsim Vaj Tsev - Kauj Ruam Ib

Nco ntsoov tias koj tau teeb tsa thaj chaw soldering thiab koj cov khoom nyob ze ntawm tes. Kuv siv daim txhuam cev los pab khaws kuv cov khoom hauv pawg thawj coj thaum kuv tig nws mus rau qhov muag … hmmm nws nyuam qhuav tshwm sim rau kuv.. yuav xiav-tack lossis qee yam ntawm cov tshuaj txhuam kom pab tuav lawv hauv qhov chaw … Kuv yuav sim qhov tom ntej thiab thiab qhia koj paub..

Luam tawm daim kab xev daim kab xev thiab muaj nws qhov twg koj tuaj yeem pom nws. Nco ntsoov tias thaum koj teeb tsa koj cov khoom siv rau hauv lub rooj tsavxwm koj yuav tsum tawm ntawm ib lub qhov ciam teb sab laug thiab sab xis yog li koj tuaj yeem xaub nws mus rau hauv lub thawv. Yog tias koj tau muaj kev paub me ntsis ntawm kev siv tshuaj - tsis txhob txhawj xeeb - muaj ntau qhov txuas hauv is taws nem thiab kab laug sab yog ib txoj hauv kev yooj yim tshaj plaws kom tau txais qee qhov kev coj ua.

Kauj Ruam 7: Txhim Kho Circuit - Kauj Ruam Ob

Thaum koj tau tsim lub Circuit Court rho tawm lub zog kawg ua, nws yog lub tswv yim zoo tsuas yog khi rau qee qhov kev coj ua ib ntus (kom lawv kov cov kab tooj liab raug) kom koj tuaj yeem ntsuas qhov Circuit. Ua ntej ntsuas qhov tam sim no nrog koj lub 'meter' thiab tom qab ntawd qhov hluav taws xob. Kho lub potentiometer kom txog thaum koj tau txais qhov xav tau hluav taws xob. Tom qab ntawd koj tuaj yeem txuas rau hauv lub zog kawg ua thiab tom qab ntawd ntxig rau hauv Circuit Court.

Tom qab ntawd koj yuav tsum tau txuas lub hwj chim nkag mus rau DC input jack (pom hauv daim duab 3 thiab 4). Koj kuj tseem yuav tsum ntxiv lub taub hau rau L200C - koj tuaj yeem pom nws hauv daim duab 4. Koj tuaj yeem pom tias cov pob zeb ntais/cov khej tau txuas nrog ib yam nkaus hauv daim duab 4. Ib qho lus qhia zaum kawg - yog tias koj lub rooj tsav xwm hauv Circuit yog xoob haum, koj ntxiv tau ob peb dabs ntawm cov kua nplaum uas lub rooj tsav xwm tau muab tso rau hauv lub thawv, piv txwv li ntawm cov neeg sib tw. Qhov no yuav tso tseg lub rooj tsavxwm nce thiab nqis. Koj tseem tuaj yeem pom los ntawm cov duab uas kuv muaj lub rooj tsav xwm nyob ntawd kom lub nti nyob ze rau hauv nruab nrab li sai tau - kom deb ntawm cov yas li kuv tuaj yeem tswj tau. Hais tias, hauv kev teeb tsa kuv xaiv lub thawv tsis kub.

Kauj ruam 8: Ua tiav

Thawj daim duab qhia txog lub thawv nrog txhua qhov kev sib txuas ua. Qhov thib 2 nrog lub hau rau thiab thib 3 thiab thib 4 them lub roj teeb.
