A LAN transformer, yomwe imadziwikanso kuti Transfoma ya Local Area Network (LAN), ndi chipangizo cholumikizira maukonde chomwe chimagwiritsidwa ntchito kulumikiza zida.Lumikizani doko la netiweki ya netiweki ku netiweki yapafupi (LAN) kudzera pa switch, ndikulumikiza intaneti ingapo kapena makompyuta ndi maseva ena mu LAN ku chipangizo chomwecho cha LAN.Lili ndi izi:
1. Palibe chifukwa chilichonse chakuthupi kapena zomveka kudzipatula pakati pa maukonde lophimba ndi malo ena kupeza malo, kotero mphamvu yake magetsi ndi ntchito dongosolo bwino kuposa makompyuta wamba, ndipo mosavuta kusinthanitsa maukonde zambiri seamlessly ndi zipangizo zina;
2. Popeza pali madoko amodzi kapena angapo mu LAN yolumikizira makompyuta ndi ma terminals ena, amathanso kukonzedwa mosavuta kuti akwaniritse zofunikira zolumikizirana pakati pa zida zosiyanasiyana;
3. Popeza madoko a switch network ndi terminal angakonzedwe padera, ntchito yosinthira maukonde imathanso kuzindikirika mosavuta.

Mfundo yogwiritsira ntchito LAN transformer:
TheLAN transformeramagwiritsidwa ntchito makamaka poteteza ma switch a netiweki.Zida za netiweki zikalephera, chosinthira sichingagwire ntchito moyenera.Ntchito yodzitetezera yokha ya LAN transformer imatha kuthetsa vutoli mofulumira komanso moyenera.Ntchito yayikulu:
1. Khazikitsani kudzipatula kwa doko kapena chitetezo cha doko pa switch kuti chosinthira chizigwira ntchito bwino.
2. Kusinthako kukalephera, dera lodzitchinjiriza lodzitchinjiriza la thiransifoma yam'deralo lidzazindikira kulephera ndikuyambiranso ntchito ya netiweki.
3. Khazikitsani malamulo osiyanasiyana oteteza ma firewall molingana ndi magawo a netiweki kuti azipatula kapena kuteteza madoko.

Cholinga chaLAN transformer:
Amagwiritsidwa ntchito kwambiri popangira mphamvu zamagetsi zamagetsi zamagetsi.Cholinga cha thiransifoma ya LAN, kuwonjezera pakupereka mphamvu pazida zina zotumizira maukonde monga ma rauta, masiwichi, ndi zina zotero, zitha kugwiritsidwanso ntchito kupereka mphamvu ku zida zina zoyankhulirana (monga AP opanda zingwe, ndi zina) ku zida zina zomwe amafuna magetsi.Transformer ya LAN ndi chipangizo chomwe chimasintha ma voltage a zida zina zomwe zimafunikira magetsi (monga ma routers, switch, etc.).Makina osinthira ma netiweki amderali nthawi zambiri amasintha mphamvu ya AC kukhala mphamvu ya DC, ndikusintha mphamvu ya 220V AC kukhala yamagetsi ya DC pafupifupi 48V, kuti zida zomwe zaperekedwa zizigwira ntchito bwino.Pazida zosiyanasiyana zoyankhulirana zomwe zimagwiritsidwa ntchito pa LAN, monga ma AP opanda zingwe, ma routers, masiwichi, ndi zina zambiri, zimafunikiranso magetsi a 24V kapena 48V kuti azipereka mphamvu zawo.Kwa zida zina zoyankhulirana zomwe zimafunikira magetsi a 24V ndi magetsi a 12v kapena 9v, thiransifoma ya LAN imatha kuthetsa vutoli.Mukamagwiritsa ntchito masiwichi, ma routers, ndi zina zotero pazigawo zoyankhulirana zoterezi, magetsi a 10 ~ 20V akhoza kusinthidwa kukhala 48 ~ 60V voltage, kotero kuti mapeto operekedwawo amatha kugwira ntchito bwino;ndizosavuta kugwiritsa ntchito ma AP opanda zingwe, muyenera kungotembenuza magetsi Ingosintha kukhala 12V-2A.
