Amandla e-POE phezu kokhuseleko lokunyuka kwe-Ethernet

Ukuphuhliswa kwe-Power over Ethernet (POE) iteknoloji yomelele kakhulu.Ukuphuhliswa kobu buchwepheshe kunokwenza lula ukufakwa kunye nokuthunyelwa kwezixhobo zombane, ngaloo ndlela kupheliswe imfuneko yemigca yokuhambisa ngokuzimeleyo.Namhlanje, iteknoloji yokubonelela ngombane (POE) isetyenziswa ngokubanzi kwiinkqubo zoshishino ezifana nokhuseleko, unxibelelwano, kunye neegridi ezihlakaniphile ukufezekisa idatha, ukuhanjiswa kwevidiyo, ukulawula ukuhamba, kunye nokunikezelwa kwamandla ngeebhasi ngaphakathi kwenkqubo.Nangona kunjalo, ngenxa yemeko enzima yokusebenza ye-Industrial Ethernet, utyando kunye nokukhuselwa okuzinzileyo kwezibuko le-POE kubalulekile.Nantsi intshayelelo emfutshane yesikimu sokhuseleko senkqubo yePOE:
Inqanaba:
(1) IEC61000-4-2: INQANABA4: Qhagamshelana ne-8kV;Umoya: 15kV
(2) IEC61000-4-5: 10/700us LEVELX: 6KV
Umgaqo: Ezi zikimu zimbini zingentla zamkela indibaniselwano yokhuselo olunamanqanaba amabini, kunye nenqanaba langaphambili libe yi-SET ye-electrostatic silicon suppressor kunye ne-negative clamp voltage suppressor NVCS, ukufunxa nokukhulula amandla amakhulu otyando.Isixhobo sokukhusela inqanaba elingasemva sisikhuseli se-electrostatic ESD, esine-voltage echanekileyo kunye nesantya sokuphendula ngokukhawuleza, Gcoba amandla ashiyekileyo enqanaba langaphambili, unciphise i-voltage ukuya kuluhlu olunokumelana nesekethe yomva, kwaye ukhusele umva- isiphelo chip.Kukhuselo lonikezelo lwamandla ombane angama-48V, izixhobo ezikhuselayo ngakumbi zisetyenziselwa ukuphucula inqanaba lovavanyo, elithatha umthamo omkhulu kwaye linefuthe elibi lolawulo kumbane oshiyekileyo, okukhokelela ekwandeni kwamathuba omonakalo wetshiphu osemva.Ngesi sizathu, i-SPSEMI Instant Thunder Electronics iphuhlise i-negative clamp voltage suppressor NVCS series material ngokukodwa iPOE (48V power supply).Esi sixhobo sinesantya esikhulu sokuhamba kunye nomthamo omncinci, ofakwe kwi-SMC.Ngokubhekiselele kulawulo lwe-voltage eshiyekileyo, malunga ne-20V ephantsi kunezixhobo ze-TVS zendabuko, ezinokukhusela ngokufanelekileyo i-chip ye-back-end.
Inqanaba:
(1) IEC61000-4-2: INQANABA4: Qhagamshelana ne-8kV;Umoya: 15kV
(2) IEC61000-4-5: 10/700us LEVELX: 6KV
Umgaqo: Ezi zikimu zimbini zingentla zamkela ukhuseleko olunamanqanaba amabini.Inqanaba elingaphambili yi-negative clamp voltage suppressor NVCS, efunxa kwaye ikhuphe amandla amakhulu otyando.Isixhobo sokhuselo senqanaba elingasemva sisikhuseli se-electrostatic ESD, esinombane obambekayo ochanekileyo kunye nesantya sokusabela ngokukhawuleza.Ithatha amandla ashiyekileyo enqanaba langaphambili, inciphisa i-voltage ngaphakathi koluhlu olunokumelana nesekethe yangasemva, kwaye ikhusela i-chip ye-back-end.
Ngokomgangatho wezizwe ngezizwe we-IEC61000-4-5, amandla ombane otyatyadula atofwa ngokubanzi ngendlela eqhelekileyo.Kuyilo lwesikimu, ingqwalasela ihlawulwa ekukhuselweni kwemodi eqhelekileyo.Umkhuseli we-electrostatic TUSD03FB wongezwa phakathi kwemigca ekwanti yokhuselo lwemowudi yokwahlula, ukuphelisa amandla ashiyekileyo adityaniswe ngasemva ngexesha lokubetha kombane, kunye nokukhusela umahluko woxinzelelo phakathi kwemigca ekutshintsheni.Esi sicwangciso sokhuseleko singentla siqinisekisiwe yi-SPSEMI Transient Thunder Electronics Laboratory.
Oku ngasentla kushwankathelo olufutshane lwe-POE Power phezu kwe-Ethernet Surge Protection, enokuthi isebenze njengesalathiso kumntu wonke.Inkampani yethu ineqela lobugcisa elomeleleyo kwaye inokubonelela ngeenkonzo zobugcisa kubathengi.Okwangoku, inkampani yethu ineemveliso ezahlukeneyo: i-onu ekrelekrele, imodyuli yonxibelelwano ye-Optical, imodyuli yefiber optical, imodyuli ye-sfp Optical, izixhobo ze-olt, iswitshi ye-Ethernet kunye nezinye izixhobo zenethiwekhi.Ukuba ufuna, unokuba nokuqonda okunzulu.
