Lub tswv yim O ~ 30V Adjustable Regulated Power Supply nrog kev ua tau zoo heev
Kev cai tso zis tau lav
Qhov tso zis ntawm lub hwj huam mov no yog tswj los ntawm ob theem thiab peb lub terminals, yog li nws tuaj yeem tau txais kev ruaj ntseg zoo (tsis qis dua ± {{0}}}.5 feem pua). Cov zis adjustable voltage ntawm 1.25 ~ 35V dhau los ntawm D6, D thiab BG: 2.8v qhov pib voltage tsim los ntawm ob lub BE junctions tuaj yeem paub qhov kev hloov pauv tas li ntawm 0 ~ 32V ntawm qhov kawg ntawm cov khoom siv hluav taws xob. Vim hais tias Darlington raj BG txuas nrog rau hauv daim ntawv ntawm emitter follower, qhov tam sim no yuav tsum tau rau peb lub davhlau ya nyob twg tso zis ntawm LM317 yog heev me me, kom ntseeg tau ib tug tas li tso zis voltage ntawm lub hwj chim mov.
txhim khu kev qha tiv thaiv
Thaum lub luv luv Circuit Court tshwm sim ntawm qhov tso zis davhlau ya nyob twg, BG nyob rau hauv lub saturated lub xeev, thiab nws tiv thaiv resistor bears tag nrho cov saturation voltage poob. Qhov voltage ntawm A thiab B poob sai sai rau 40V lossis qis dua, BGi raug txiav tawm, ob qhov kawg ntawm relay J_excitation coil raug tso tawm vim tsis muaj 24V excitation voltage, J raug txiav, thiab T -transformer raug kaw ib zaug, thiab D qhia tias lub teeb-emitting raj tawm mus, tag nrho lub tshuab tsis ua haujlwm, thiab kev tiv thaiv luv luv ua tiav. Nyob rau hauv tib txoj kev, thaum lub voltage ntawm ob kawg ntawm A thiab B yog<40V, the protection circuit operates, BG- is cut off, Jl is released, and the whole machine also stops working, realizing the over-current protection action. If you want to restart the power supply, you need to release the short circuit state, press the reset button to restart the whole machine. . The instrument completes the overcurrent protection and short circuit protection with the same protection circuit, which realizes the ultimate protection control and provides a strong guarantee for the reliable operation of the whole machine.
Kev siv lub sijhawm ntev ntawm cov khoom siv hluav taws xob no hauv peb txoj haujlwm tiag tiag tau ua pov thawj tias nws muaj kev ua haujlwm ruaj khov, muaj kev ntseeg siab, ua haujlwm yooj yim thiab muaj zog ua haujlwm. Ntxiv rau qhov tsim nyog rau kev tshawb fawb thiab kev tsim cov khoom siv hluav taws xob dav dav, nyob rau hauv cov xwm txheej ntawm cov khoom me me. Nws kuj tseem tuaj yeem muab qhov chaw ruaj khov rau qhov ntsuas ntsuas ntsuas qhov ntsuas. Ntawm no, cov khoom siv hluav taws xob kuj tseem tuaj yeem txuas ntxiv mus rau plaub qhov kev tso tawm ywj pheej (4 pawg ntawm cov cua ntsawj ntshab thib ob yog qhov txhab ntawm qhov kawg ntawm lub tshuab hloov pauv), thiab ntau yam kev tso tawm ywj pheej xws li 0 ~ 60V, 0-120V , ± 30v, thiab ~ 60V tuaj yeem tau yooj yim. Cov khoom siv hluav taws xob zoo li no nthuav dav rau kev siv lub sijhawm ntawm cov khoom siv hluav taws xob.
