Kuti mukwaniritse ntchito yabwino yamagetsi a benchtop, ndikofunikira kumvetsetsa mfundo zake zoyambira. Magetsi a benchtop amasintha mphamvu yolowera ya AC kuchokera pakhoma kukhala mphamvu ya DC yomwe imagwiritsidwa ntchito kupatsa mphamvu zida zosiyanasiyana mkati mwa kompyuta. Nthawi zambiri imagwira ntchito pagawo limodzi la AC ndipo imapereka ma voltages angapo a DC, monga +12V, -12V, +5V, ndi +3.3V.
Kuti asinthe magetsi a AC kukhala magetsi a DC, magetsi opangira benchi amagwiritsa ntchito thiransifoma kuti asinthe ma voliyumu okwera kwambiri komanso mphamvu yolowera ya AC kukhala yocheperako komanso siginecha yapamwamba ya AC. Chizindikiro cha AC ichi chimakonzedwanso pogwiritsa ntchito ma diode, omwe amasintha siginecha ya AC kukhala voteji ya DC.
Kuti muchepetse mphamvu yamagetsi ya DC, magetsi apakompyuta amagwiritsa ntchito ma capacitor omwe amasunga kuchuluka kwake ndikumamasula panthawi yamagetsi otsika, zomwe zimapangitsa kuti magetsi a DC azikhazikika. Mphamvu yamagetsi ya DC imayendetsedwa pogwiritsa ntchito ma voltage regulator circuit kuti iwonetsetse kuti imakhalabe mkati mwa kulekerera kolimba, kuteteza kuwonongeka kwa zigawozo. Zodzitchinjiriza zosiyanasiyana, monga chitetezo champhamvu kwambiri, chitetezo chopitilira muyeso, ndi chitetezo chafupipafupi, zimamangidwanso mumagetsi apakompyuta kuti ateteze kuwonongeka kwa zinthuzo ngati pangakhale zolakwika.
Kumvetsetsa mfundo zazikuluzikulu zamagetsi apakompyuta kungathandize posankha magetsi oyenera pamakompyuta ndikuwonetsetsa kuti akugwira ntchito bwino.
M'nkhaniyi, tikambirana zofunikira za magetsi a benchtop, momwe angagwiritsire ntchito moyenera, ndi zomwe muyenera kuyang'ana posankha chitsanzo.
Kodi Benchtop Power Supply ndi chiyani?
Pamene mukugwira ntchito yomwe imafuna mphamvu yeniyeni ya DC, magetsi a benchtop amatha kukhala othandiza. Kwenikweni magetsi ang'onoang'ono omwe adapangidwa kuti azikhala pa benchi yanu yogwirira ntchito.
Zidazi zimadziwikanso kuti magetsi a lab, magetsi a DC, ndi magetsi osinthika. Iwo ndi angwiro kwa zamagetsi kwa iwo amene amafunikira mwayi wodalirika komanso wosavuta kugwiritsa ntchito gwero lamagetsi.
Ngakhale pali mitundu ingapo ya zida zamagetsi zomwe zilipo - kuphatikiza zolumikizirana, zotulutsa zambiri, ndi zina zokhala ndi mawonekedwe osiyanasiyana - zonse zidapangidwa kuti ntchito zanu zikhale zosavuta komanso zolondola.
Zimagwira ntchito bwanji?
Magetsi a benchtop ndi chida chosunthika chomwe chimapereka mphamvu zoyendetsedwa ndi zida zamagetsi. Imagwira ntchito pojambula chingwe chamagetsi cha AC kuchokera pa mains ndikusefa kuti ipereke kutulutsa kwa DC kosalekeza. Njirayi imaphatikizapo zigawo zingapo, kuphatikizapo transformer, rectifier, capacitor, ndi voltage regulator.
Mwachitsanzo, pamagetsi amtundu wamagetsi, chosinthira chimatsitsa voteji kuti chifike potha kutha, chowongolera chimatembenuza AC pano kukhala DC, capacitor imasefa phokoso lililonse lomwe latsala, ndipo chowongolera magetsi chimatsimikizira kutulutsa kokhazikika kwa DC. Ndi kuthekera kosintha ma voliyumu ndi milingo yapano ndikuteteza zida kuti zisawonongeke, magetsi a benchtop ndi chida chofunikira pamakina owunikira okha, kuthandizira kusukulu, ndi zina zambiri.
Chifukwa chiyani kuli kofunikira?
Chida chamagetsi pa benchi sichingakhale chida chokongola kwambiri mu labu ya mainjiniya amagetsi, koma kufunikira kwake sikunganenedwe mopambanitsa. Popanda mmodzi, kuyesa ndi prototyping sikungatheke poyamba.
Zida zamagetsi za benchtop zimapereka gwero lodalirika komanso lokhazikika lamagetsi poyesa ndikuwongolera mabwalo amagetsi. Amalola mainjiniya kuti asinthe ma voltage ndi apano kuti ayese malire awo, kuwona momwe amagwirira ntchito zosiyanasiyana, ndikuwonetsetsa kuti azigwira bwino ntchito yomaliza.
Kuyika ndalama pamagetsi apamwamba a benchtop sikungawoneke ngati kugula kwabwino kwambiri. Komabe, zitha kuthandizira kwambiri pakuchita bwino komanso magwiridwe antchito amagetsi ndi chitukuko.
