PoE (Power over Ethernet) imatanthawuza mphamvu paukadaulo wa Efaneti yomwe imatumiza nthawi imodzi mphamvu ndi data kudzera pa chingwe chopotoka. Kugwiritsa ntchito ukadaulo uwu kumatha kupititsa patsogolo kukhazikika komanso kusinthasintha kwa maukonde, motero amakondedwa kwambiri ndi anthu. Pakalipano, pali mapulogalamu osiyanasiyana otengera luso la PoE pamsika, monga ma switch a Gigabit PoE, magetsi a PoE, ma splitter a PoE, ndi zina zotero.

Panja PoE Injector POE++ 60/90w 802.3af/at

Kodi injector ya PoE ndi chiyani?

Injector ya PoE imatchedwanso midspan, PoE charger kapena poE adapter. Imagwirizanitsa masiwichi osakhala a PoE ndi zida zoyendetsedwa ndi PoE (PD) kudzera pazingwe zama network (monga Cat5eCat6Cat6a, etc.) zikugwira ntchito. Chipangizochi nthawi zambiri chimakhala choyenera malo omwe amafunikira kukhazikitsa zida zotsika mphamvu zochepa koma opanda magetsi. Njira yothetsera vutoli imakwaniritsa bwino kwambiri kusinthasintha kwa maukonde pamtengo wotsika, kotero kuti kuyika zida sikuletsedwanso ndi kamangidwe ka malo komanso komwe kulipo kale.

Ubwino wa jekeseni wa PoE umawonekera makamaka pazinthu izi:
*N'zosavuta kukhazikitsa: Ingolumikizani magetsi ku zida za PoE terminal ndi chosinthira kuti mupereke thandizo lamagetsi ndi data.
*Zosavuta kukulitsa: Kutulutsa kwa siginecha ya data ndi siwichi ya non-PoE kumatha kubayidwa mu siginecha yamagetsi kudzera pa chingwe cha netiweki, kuti apereke mphamvu ndi chithandizo chotumizira deta pa chipangizo choyendetsedwa nthawi yomweyo, zomwe zimabweretsa kusavuta. ku kulumikizana kwa chipangizocho.
* Sungani ndalama: Kugwiritsa ntchito magetsi a PoE kumatha kusunga mamangidwe oyambira pamanetiweki pamaziko ogwiritsira ntchito zida zoyambira, motero kupulumutsa ndalama zambiri.

Mtundu wa jekeseni wa PoE:

Kupereka Mphamvu kwa PoE Wokhazikika & Kupereka Mphamvu kwa PoE Osakhala wamba

Magetsi okhazikika a PoE amatanthauza mphamvu yamagetsi yomwe imagwirizana ndi miyezo yamakampani a PoE (monga IEEE802.3af, IEEE802.3at kapena mulingo waposachedwa wa IEEE802.3bt). Pansi pa muyeso wamakampani a PoE a 802.3af, 802.3at kapena 802.3bt, zida zamagetsi za PoE (PSE) ndi zida zoyendetsedwa ndimagetsi zimangokambirana zokha zikalumikizidwa, ndipo zokambirana zitha kupambana pokhapokha zida zomwe zili mbali zonse ziwiri zikugwirizana ndi momwemonso muyezo. Pambuyo pokambirana pakati pa zipangizo ziwirizi, chipangizo chogwiritsira ntchito magetsi chidzapereka mphamvu ku chipangizo chamagetsi. Munjira iyi yaukadaulo wamba wa PoE, chitetezo cha zida za PoE zitha kutsimikiziridwa mwamphamvu. Nthawi zambiri, 802.3af, 802.3at kapena 802.3bt voteji yamagetsi ndi 44-57V (DC).

Mphamvu zamagetsi za PoE zomwe sizili wamba nthawi zambiri zimatengera mphamvu zamagetsi zomwe sizitsatira miyezo yamakampani a PoE (monga IEEE802.3af, IEEE802.3at kapena IEEE802.3bt). Magetsi ogwiritsira ntchito a zida zosagwirizana ndi PoE nthawi zambiri amakhala 18-48V (DC). Ngati ma voltage a zida ziwiri zolumikizidwa sizikugwirizana, zitha kuwononga chipangizocho.

12V/24V/48V PoE magetsi

PoE magetsi akhoza kugawidwa m'magulu atatu malinga ndi mphamvu yamagetsi: 12V, 24V ndi 48V. Mukamagula magetsi a PoE, muyenera kuganizira ngati voteji ya chipangizo cha PoE cholumikizidwa nayo ndiyofanana.

Kuphatikiza pa magulu awiri omwe atchulidwa pamwambapa, PoE Injector imathanso kugawidwa malinga ndi kuchuluka kwa madoko osiyanasiyana, monga doko limodzi la PoE magetsi ndi madoko asanu ndi atatu a PoE ndi zina zotero.
