PoE (Power dua Ethernet) yog hais txog lub hwj chim tshaj Ethernet thev naus laus zis uas ib txhij xa hluav taws xob thiab cov ntaub ntawv los ntawm cov kab sib tw twisted. Daim ntawv thov ntawm cov thev naus laus zis no tuaj yeem txhim kho kev ruaj ntseg thiab yooj yim ntawm lub network, yog li nws tau nyiam los ntawm tib neeg. Tam sim no, muaj ntau daim ntawv thov raws li PoE thev naus laus zis ntawm kev ua lag luam, xws li Gigabit PoE keyboards, PoE cov khoom siv hluav taws xob, PoE splitters, thiab lwm yam.

PoE injector yog dab tsi?

PoE injector tseem hu ua midspan, PoE charger lossis PoE adapter. Nws txuas tsis-PoE keyboards thiab PoE powered li (PD) los ntawm network cables (xws li Cat5eCat6Cat6a, thiab lwm yam) ua hauj lwm. Cov cuab yeej no feem ntau haum rau cov chaw uas yuav tsum tau nruab cov cuab yeej siv hluav taws xob tsawg tab sis tsis muaj hluav taws xob hluav taws xob. Qhov kev daws teeb meem no ua rau muaj kev txhim kho zoo hauv kev sib txuas hauv network ntawm tus nqi qis, yog li cov cuab yeej teeb tsa tsis raug txwv los ntawm thaj chaw thiab cov khoom siv network uas twb muaj lawm.

Qhov zoo ntawm PoE injector feem ntau yog tshwm sim hauv cov hauv qab no:
* Yooj yim rau nruab: Tsuas yog txuas cov khoom siv hluav taws xob mus rau PoE cov khoom siv davhlau ya nyob twg thiab qhov hloov pauv kom muab lub zog thiab cov ntaub ntawv xa mus.
* Yooj yim nthuav: Cov ntaub ntawv teeb liab tso tawm los ntawm qhov tsis yog-PoE hloov pauv tuaj yeem raug txhaj rau hauv lub zog teeb liab los ntawm lub network cable, txhawm rau muab lub zog thiab cov ntaub ntawv xa mus rau cov khoom siv hluav taws xob tib lub sijhawm, uas coj kev yooj yim dua. mus rau kev sib txuas ntawm lub cuab yeej.
* Txuag cov nuj nqis: Kev siv cov khoom siv hluav taws xob PoE tuaj yeem khaws cov khoom qub hauv lub network raws li kev siv cov khoom qub, yog li txuag tau nyiaj ntau.

PoE injector hom:

Standard PoE Power Supply & Non-standard PoE Power Supply

Standard PoE fais fab mov yog hais txog lub hwj huam mov uas ua raws li PoE cov qauv kev lag luam (xws li IEEE802.3af, IEEE802.3at lossis IEEE802.3bt tus qauv tshiab). Raws li PoE kev lag luam tus qauv ntawm 802.3af, 802.3at lossis 802.3bt, PoE cov khoom siv hluav taws xob (PSE) thiab cov cuab yeej siv hluav taws xob yuav cia li sib tham thaum lawv txuas nrog, thiab kev sib tham yuav ua tiav tsuas yog thaum cov khoom siv ntawm ob qho tag nrho ua raws li. tib hom qauv. Tom qab kev sib tham ntawm ob lub cuab yeej ua tiav, cov khoom siv hluav taws xob yuav muab lub zog rau cov khoom siv hluav taws xob. Hauv hom kev ua haujlwm no ntawm tus qauv PoE thev naus laus zis, kev nyab xeeb ntawm cov khoom siv PoE tuaj yeem lav tau zoo. Feem ntau, 802.3af, 802.3at lossis 802.3bt tus qauv fais fab mov voltage yog 44-57V (DC).

Cov khoom siv hluav taws xob tsis yog PoE feem ntau xa mus rau cov khoom siv hluav taws xob uas tsis ua raws li cov qauv kev lag luam PoE (xws li IEEE802.3af, IEEE802.3at lossis IEEE802.3bt qauv). Kev khiav hauj lwm voltage ntawm cov khoom siv tsis-tus qauv PoE feem ntau yog 18-48V (DC). Yog tias qhov ntsuas hluav taws xob ntawm ob qhov txuas txuas tsis sib xws, nws yuav ua rau muaj kev puas tsuaj mus tas li rau lub cuab yeej.

12V / 24V / 48V PoE fais fab mov

PoE fais fab mov tuaj yeem muab faib ua peb hom raws li qhov tso zis hluav taws xob: 12V, 24V thiab 48V. Thaum muas PoE fais fab mov, koj yuav tsum xav txog seb qhov voltage ntawm PoE cov cuab yeej txuas nrog nws zoo ib yam.

Ntxiv rau cov lus hais saum toj no ob pawg ntawm cov khoom siv hluav taws xob, PoE Injector kuj tseem tuaj yeem muab faib raws li tus naj npawb ntawm cov chaw nres nkoj sib txawv, xws li ib qho chaw nres nkoj PoE fais fab mov thiab yim-chaw nres nkoj PoE fais fab mov thiab lwm yam.
