Cov haujlwm tseem ceeb ntawm DC stabilized voltage thiab tam sim no stabilized fais fab mov, ceev faj rau kev siv lub hwj chim mov
Qhov no yog ib qho khoom siv hluav taws xob uas tuaj yeem muab lub zog DC ruaj khov rau lub nra. Feem ntau DC tswj fais fab khoom siv hluav taws xob yog cov khoom siv hluav taws xob AC. Qhov hluav taws xob DC tso zis hluav taws xob ntawm kev tswj hwm hluav taws xob tseem nyob ruaj khov txawm tias qhov hluav taws xob ntawm AC qhov chaw lossis qhov hloov pauv hloov pauv. Nrog rau txoj kev loj hlob ntawm cov khoom siv hluav taws xob nyob rau hauv cov kev taw qhia ntawm high precision, siab stability thiab siab ntseeg, DC tswj fais fab khoom muab tso rau pem hauv ntej siab yuav tsum tau rau lub hwj chim ntawm cov khoom siv hluav taws xob.
1. Cov haujlwm tseem ceeb ntawm DC tswj fais fab mov
1. Tus nqi hluav taws xob tso zis tuaj yeem teeb tsa arbitrarily, thiab nws tuaj yeem ua haujlwm ib txwm nyob rau hauv cov xwm txheej ntawm qis dua tus nqi tso zis voltage.
2. Tus nqi tsis tu ncua tam sim no ntawm cov zis tam sim no tuaj yeem teeb tsa arbitrarily, thiab nws ua haujlwm ib txwm thaum nws qis dua qhov ntsuas cov zis tam sim no.
3. Lub xeev ruaj khov thiab ruaj khov tam sim no ntawm DC fais fab mov yuav raug hloov dua siab tshiab, thiab lub xeev sib thooj yuav tshwm sim.
4. Cov zis voltage thiab tam sim no qhov tseem ceeb yuav tsum raug muab tso tawm kom raug thiab txheeb xyuas.
5. Rau cov khoom siv hluav taws xob DC uas xav tau qhov tseeb tso zis hluav taws xob thiab qhov tseem ceeb tam sim no, ntau lub tshuab tig potentiometers thiab potentiometers rau qhov zoo-tuning voltage thiab tam sim no lossis ncaj qha digital input feem ntau yog siv.
6. Yuav tsum muaj kev tiv thaiv kom tiav. Txawm hais tias cov zis terminals yog luv luv thiab ua qhov txawv txav, cov tswj DC fais fab mov yuav tsum tsis txhob puas. Tom qab qhov kev zam raug daws lawm, nws yuav ua haujlwm li qub.
2. Cov teeb meem xav tau kev saib xyuas thaum siv DC stabilized voltage thiab stabilized tam sim no fais fab mov
1. Ua ntej maj mam kho lub pob "coarse" raws li qhov xav tau nro, tom qab ntawd maj mam kho lub pob "zoo" kom ntseeg tau tias haum. Piv txwv li, yog tias koj xav tau qhov hluav taws xob ntawm 12V, koj yuav tsum teeb tsa lub pob "hloov kho" mus rau 15V, thiab tom qab ntawd teeb lub pob "hloov zoo" rau 12V, txwv tsis pub nws yuav tsis ncav cuag 12v, thiab qhov siab tshaj plaws tso zis voltage yuav. tsis ncav cuag 12V.
2. Teem qhov xav tau qhov hluav taws xob thiab rov txuas nws rau lub nra.
3. Yog tias koj yuav tsum tau hloov lub iav "coarse adjustment" thaum lub sijhawm ua haujlwm, koj yuav tsum xub txiav lub load, teeb tsa cov zis hluav taws xob mus rau qhov xav tau, thiab tom qab ntawd txuas lub load.
4. Yog hais tias lub load yog luv luv los yog overloaded thaum lub sij hawm ua hauj lwm, thov disconnect lub load ua ntej, ces nias lub "Resume" khawm los yog tua lub hwj chim thiab tig rau nws rov qab rau lub voltage mus rau lub qub kev khiav hauj lwm lub xeev. Txuas tom qab teeb meem kev thauj khoom.
5. Thaum txuas cov khoom siv hluav taws xob nrog cov sib txawv nominal tam sim no nyob rau hauv series, cov zis tam sim no yuav tsum sib haum rau tus nqi nominal ntawm qhov tsawg kawg nkaus nominal tam sim no.
6. Txhua lub hwj huam mov muaj lub ntsuas lub taub hau rau kev nthuav tawm cov zis tam sim no lossis cov zis hluav taws xob ntawm cov channel hauv cov xeev A / V sib txawv. Feem ntau muab tso rau hauv qhov ntsuas qhov ntsuas hluav taws xob.
7. Txhua channel muaj ob qhov tso zis connectors, liab thiab dub. Ib qho kev sib txuas liab sawv cev rau "ntxiv", qhov kev sib txuas dub sawv cev rau "-", thiab kev sib txuas dub nrog lub cim dub "lub ntiaj teb" nyob rau hauv nruab nrab ntawm cov tswj vaj huam sib luag sawv cev rau kev sib txuas. Txuas rau lub tsev, thiab txuas mus rau txhua qhov hluav taws xob. Ib qho kev tso zis tsis muaj hluav taws xob sib txuas thiab tsuas yog siv los ua cov xaim kev nyab xeeb xwb. Nws yog ib qho yooj yim to taub tias lub cim "hauv av" txhais tau tias hauv av, thiab "ntxiv" thiab "-" txhais tau hais tias lub zog zoo thiab qhov tsis zoo uas ua rau lub op amp ntawm ob lub zog.
8. Ob qhov hluav taws xob tuaj yeem txuas nrog hauv series. Txwv tsis pub siv ib txhij. Txij li cov khoom siv hluav taws xob yog cov khoom siv hluav taws xob, cov khoom siv hluav taws xob tsis tuaj yeem ua rau luv luv rau lub sijhawm ntev.
