SIV LUB TSEV KAWM NTAWV
Ntu no muab ib qho ntxivview ntawm cov kev sib txuas thiab con-figuration xaiv ntawm CTD221-BB-1.5 kev ntsuam xyuas pawg thawj coj saib. Txhua pawg kev sib txuas uas tau hais tseg hauv daim duab 2 muaj cov ncauj lus nthuav dav hauv qab no. Cov ntaub ntawv cov khoom lag luam muaj cov ncauj lus kom ntxaws txog kev siv thiab kev ua haujlwm ntawm txhua tus pin thiab yuav tsum tau sab laj rau cov ntaub ntawv nthuav dav dua li muaj nyob hauv phau ntawv qhia tus neeg siv no.
Lub Rooj Tswjhwm Saib Xyuas Kev Ntsuam Xyuas yog siv los ntawm kev sib txuas ntawm DV bias voltage ntawm VCC thiab GND pins ntawm PCB. Lub OUT tus pin ntawm PCB yuav tsum txuas nrog lub digital voltmeter (DVM) lossis oscilloscope los saib xyuas cov zis ntawm CT220 tam sim no sensor. Cov ntaub ntawv tam sim no nyob rau hauv seem no yog rau 5 V bias voltage.
Hom qis tam sim no
Hauv hom qis tam sim no, tam sim no dhau los ntawm 0.9 hli-dav kab nyob rau sab saum toj txheej ntawm PCB. Hom no tuaj yeem siv los ntsuas qhov tam sim no hauv thaj tsam ntawm ± 3.85 A. Kev tshem tawm ntawm cov kab thiab IC pads yog 0.35 hli, uas muab kev sib cais ntawm 1 kV ntawm cov kab tam sim no thiab SOT23 tus pins. Ntxiv rau qhov zoo tshaj plaws linearity thoob plaws qhov kub thiab txias, lub teeb liab-rau-lub suab nrov piv (SNR) ntawm CT220 ua rau nws ntsuas qhov qis qis heev. CTD221 tuaj yeem ntes cov tam sim no tsawg li 5 mA.
Nruab nrab-Tam sim no hom
Nyob rau hauv nruab nrab-tam sim no hom, tam sim no dhau los ntawm 2 hli-dav kab nyob rau hauv qab txheej ntawm PCB. Qhov kev nthuav dav no (piv rau hom qis tam sim no) tso cai rau pom qhov tam sim no loj dua. Hom no tuaj yeem siv los ntsuas qhov tam sim no ntawm ± 10 A, nrog rau kev daws teeb meem hauv 10 mA cov kauj ruam. Kev rho tawm ntawm CT220 rau qhov kev teeb tsa no yog 5.1 kVrms vim qhov kev ncua deb ntawm cov kab hauv qab thiab SOT23 tus pins yog 1.6 hli.
High-Tam sim no hom
Hom-tam sim no siab yog siv rau cov ntawv thov uas muaj cov dej ntws loj dhau los ntawm PCB kab. Nyob rau hauv hom no, tam sim no yog dhau los ntawm tooj liab busbar. Lub busbar yog 1/2 "dav thiab 1/16" tuab. Tus neeg siv tau yooj yim los kho qhov kev ncua deb ntawm lub busbar los ntawm sab saum toj ntawm PCB siv yas, temper-ature-resistant washers. CTD221 kev soj ntsuam pawg thawj coj yog xa nrog spacers kom muaj qhov sib txawv ntawm 4 hli ntawm PCB thiab lub busbar. Nrog rau qhov kev teeb tsa no, CTD221 tuaj yeem siv los ntsuas qhov tam sim no hauv tag nrho ntawm 50 A thiab ntsuas qhov tam sim no hauv thaj tsam ntawm ± 50 A nrog 50 mA daws teeb meem. Nrog rau qhov sib nrug ntawm 4 hli ntawm CT220 thiab lub busbar, qhov kev sib cais voltage tshaj 5.1 kVrms nyob rau hauv high-tam sim no hom.
