tsananguro pfupi:

Iyo TPS23861 iri nyore kushandisa, inochinjika, IEEE802.3at PSE mhinduro.Sekutumirwa, inongozvibata ina 802.3at zviteshi pasina kudiwa kwehutongi hwekunze.
Iyo TPS23861 inoona otomatiki Powered Devices (PDs) ine siginecha inoshanda, inosarudza simba rinodiwa zvinoenderana nemhando uye inoshandisa simba.Zviviri-zviitiko kupatsanurwa kunotsigirwa mhando-2 PDs.Iyo TPS23861 inotsigira DC kubviswa uye ekunze FET architecture inobvumira vagadziri kuyera saizi, kunyatsoita uye mhinduro yemutengo zvinodiwa.

PoE & PSE

PoE inozivikanwawo seSimba pamusoro peEthernet (PoL, Simba pamusoro peLAN) kana Active Ethernet, kana dzimwe nguva kungoti Simba pamusoro peEthernet.
Zvishandiso zvakajairika zvePoE zvinosanganisira kuchengetedzwa kwekutarisa, IP telephony, uye isina waya yekuwana nzvimbo (WAPs).Chishandiso kana kuti mid-span mudziyo unoshandiswa kugovera magetsi ndiwo wemagetsi ekushandisa (PSE).Mutoro wakabatana neEthernet connector ndiyo mudziyo wemagetsi (PD).
Iyo PoE protocol yekudzora simba remutoro pakati pePSE nePD inotsanangurwa neIEEE 802.3bt chiyero.Transformer inodiwa paEthernet host port, midspan, uye hub nzvimbo kuunza data mutambo.Mukuwedzera, iyo DC voltage inogona kuiswa kune yepakati pombi ye transformer pasina kukanganisa chiratidzo chedata.Sezvinoita chero tambo yekufambisa magetsi, tekinoroji iyi inoshandisa yakakwira voltage (inenge 50V) kuchengetedza ikozvino yakaderera uye kuderedza mhedzisiro yeIR voltage kudonha mumutsara, nekudaro kuchengetedza kuendesa simba kumutoro.Iyo yakajairwa 2-waya peya PoE inoburitsa ingangoita 13W kuClass 1 PDs uye ingangoita 25.5W kuClass 2 PDs, nepo yakajairwa 4-waya peya PoE ichikwanisa kuendesa ingangoita 51W kuClass 3 PDs uye ingangoita 71W kuClass 4 PDs.

Mitemo

Zviyero zvitatu zvePoE magetsi ekupa
1. EEE802.3af Main magetsi emagetsi parameters.
DC voltage iri pakati pe44 ne57V, yakajairika kukosha ndeye 48V.yakajairika kushanda ikozvino 10 kusvika 350mA, yakajairika kubuda simba: 15.4W.yakawandisa yekuona parizvino ndeye 350 kusvika 500mA.pasi pemamiriro asina-mutoro, iyo yakanyanya kudiwa ikozvino 5mA.mana Makirasi mazinga emagetsi ekukumbira simba kubva pa3.84 kusvika 12.95W anopihwa ePD zvishandiso.
IEEE802.3af classification parameters.
Zvishandiso zveClass0 zvinoda simba guru rekushandisa re0 kusvika 12.95W.
Zvishandiso zveClass1 zvinoda simba rekushandisa rinopfuura 0 kusvika 3.84W.
Zvishandiso zveClass2 zvinoda simba rekushandisa pakati pe3.85W ne6.49W.
Zvishandiso zveClass3 zvinoda huwandu hwemagetsi kubva pa6.5 kusvika 12.95W.
2. IEEE802.3at (PoE +) Mitemo yemagetsi makuru.
DC voltage iri pakati pe50 ne57V, kukosha kwakajairika i50V.Iyo yakajairika inoshanda ikozvino igumi kusvika 600mA, yakajairwa kubuda simba: iri 30W.powered device PD inotsigira Class4 classification.

IEEE802.3bt (PoE++)

Iyo 802.3bt yakatarwa inosuma ina itsva-yepamusoro-simba PD kupatsanura (Kirasi), kuunza huwandu hwese hwemakirasi echikamu chimwe kusvika kumapfumbamwe.Kirasi5 kusvika ku8 mitsva kune chiyero chePoE uye inoturikira muPD simba mazinga e40.0W kusvika 71W.

802.3bt iri kumashure inoenderana ne802.3at uye 802.3af.Simba rakaderera 802.3at kana 802.3af PD rinogona kubatanidzwa kune simba repamusoro 802.3bt PSE pasina matambudziko.Uye kana simba repamusoro 802.3bt PD rakabatana kune simba rakaderera 802.3at kana 802.3af PSE, maPDs anongoda kukwanisa kushanda kune dzimwe nzvimbo dzakaderera dzemasimba, iyo inonzi "degradation".
