Dab tsi yog kev ceev faj thaum siv DC stabilized fais fab mov?
1. Cov haujlwm tseem ceeb ntawm DC tswj cov khoom siv hluav taws xob. Ntau qhov tso zis feem ntau muaj nyob hauv DC tswj cov khoom siv hluav taws xob:
Piv txwv li, muaj ib qho kev tso tawm ruaj khov muaj nyob ntawm 5V thiab 2A, thiab muaj ob qhov kev hloov kho tau (A thiab B) muaj nyob ntawm 0 ~ 24V thiab 0 ~ 1A. Kev ruaj ntseg tam sim no thiab voltage stabilization yog ob hom kev ua haujlwm tseem ceeb ntawm cov zis adjustable. Lub ntsuas hluav taws xob pem hauv ntej LED qhia txog CV thiab CC hom, uas tau hloov pauv ntawm ob hom kev ua haujlwm no thaum lub thauj khoom sib txawv. Feem ntau, lub teeb liab qhia txog qhov tam sim no tsis tu ncua (CC) thaum lub teeb ntsuab qhia tias muaj hluav taws xob ruaj khov (CV). Tsis tas li ntawd, qee qhov kev tswj hwm hluav taws xob muaj kev tswj hwm tus qhev thiab A thiab B series ua haujlwm. Thaum nyob rau hauv kev khiav hauj lwm hom, qhov tso zis voltage ntawm qhev Circuit Court hloov nyob rau hauv tandem nrog lub ntsiab Circuit Court yog txoj kev A yog lub ntsiab Circuit Court thiab txoj B yog qhev Circuit Court. Qhov no ua rau nws tsim nyog rau cov xwm txheej uas xav tau kev siv hluav taws xob bipolar symmetrical. Nws muaj peev xwm tso zis 0~48V, 0~1A DC fais fab mov thaum txuas hauv series nrog B; nyob rau hauv series taug qab hom, nws muaj peev xwm tso zis 024V, 0 ~ 1A DC fais fab mov.
Kev ceev faj rau kev siv
1. Los lav kev sib koom tes kom zoo, tig lub pob qhov "coarse adjustment" ua ntej raws li qhov tsim nyog voltage, thiab tom qab ntawd lub pob qhov "hloov zoo" maj mam. Piv txwv li, koj yuav tsum tau teeb tsa "kev hloov kho kom zoo" pob qhov rooj rau 12V thiab "kev hloov kho ntxhib" rau 15V thaum koj xav tau tsim 12V ntawm lub zog. Txawm li cas los xij, koj yuav tsum tsis txhob teeb tsa "kev hloov kho ntxhib" pob qhov rooj rau 10V. Yog tsis yog, qhov siab tshaj plaws tso zis voltage yuav tsis yog 12V.
2. Txuas lub thauj khoom tom qab hloov mus rau qhov tsim nyog voltage.
3. Thaum hloov lub iav "coarse adjustment" thaum lub cuab yeej ua haujlwm, disconnect lub load pib, thiab reconnect nws ib zaug cov zis voltage tau coj mus rau theem tsim nyog.
4. Nyob rau hauv cov ntaub ntawv uas ib tug load luv luv Circuit Court los yog overload tiv thaiv thaum lub sij hawm siv, disconnect lub load ua ntej nias lub "Reset" khawm los yog tig lub hwj chim rov qab mus rau lub qub voltage ua hauj lwm. Thaum qhov teeb meem tau daws lawm, rov txuas nws dua. nqa.
5. Cov zis tam sim no ntawm cov txheej txheem ntawm cov khoom siv hluav taws xob sib txawv nrog cov ntsuas ntsuas sib txawv yog sib npaug rau cov nqi ntsuas hluav taws xob nrog cov ntsuas qis tshaj tam sim no.
6. Ib lub 'meter' uas qhia tau hais tias cov channel tso zis voltage lossis tam sim no nyob rau hauv ntau lub xeev A / V yog suav nrog txhua qhov khoom siv hluav taws xob. Feem ntau nyob rau hauv lub xeev ntawm qhov taw qhia voltage.
7. Ob qhov tso zis tawm rau txhua lub channel yog xim dub thiab liab. "+" yog sawv cev los ntawm lub davhlau ya nyob twg liab, thiab "-" yog sawv cev los ntawm lub davhlau ya nyob twg dub. Hauv nruab nrab ntawm lub vaj huam sib luag, muaj lub davhlau ya nyob twg dub uas txuas nrog lub cim "lub ntiaj teb", qhia tias nws txuas nrog ob lub chassis thiab txhua lwm lub davhlau ya nyob twg. Ib qho kev tso zis tsuas yog siv los ua ib txoj hlua ruaj ntseg thiab raug txiav tawm hluav taws xob. Qee tus neeg nquag siv nws kom pom zoo tias "+" thiab "-" cov cim sawv cev rau qhov zoo thiab qhov tsis zoo ntawm lub zog siv hluav taws xob siv hluav taws xob dual fais fab mov op amps, thiab lub cim "lub ntiaj teb" qhia txog av.
8. Nws tuaj yeem siv ob qhov hluav taws xob hauv series. Kev siv Parallel yog txwv tsis pub siv. Txij li thaum lub hwj chim mov yog ib qho cuab yeej siv, ncua luv luv Circuit Court ntawm cov zis davhlau ya nyob twg yog tsis tso cai.
