POE Hwj chim dhau Ethernet surge tiv thaiv

Txoj kev loj hlob ntawm Lub Hwj Chim dhau Ethernet (POE) thev naus laus zis muaj zog heev. Kev txhim kho ntawm cov thev naus laus zis no tuaj yeem ua kom yooj yim rau kev teeb tsa thiab kev xa khoom ntawm cov khoom siv hluav taws xob, yog li tshem tawm qhov xav tau ntawm cov kab sib txuas ywj pheej. Tam sim no, lub tshuab hluav taws xob siv hluav taws xob (POE) tau siv dav hauv kev lag luam xws li kev ruaj ntseg, kev sib txuas lus, thiab cov phiajcim ntse kom ua tiav cov ntaub ntawv, kev sib kis video, kev tswj dej ntws, thiab kev siv hluav taws xob los ntawm cov tsheb npav hauv qhov system. Txawm li cas los xij, vim muaj kev ua haujlwm hnyav ntawm Industrial Ethernet, qhov kev tiv thaiv zoo li qub ntawm POE chaw nres nkoj yog qhov tseem ceeb. Ntawm no yog cov lus qhia luv luv rau txoj kev tiv thaiv ntawm POE system:
Qib:
(1) IEC61000-4-2: LEVEL4: Hu rau 8kV; Cua: 15kV
(2) IEC61000-4-5: 10/700us LEVELX: 6KV
Lub hauv paus ntsiab lus: Ob lub tswv yim saum toj no tau txais kev sib koom ua ke ntawm ob-theem tiv thaiv, nrog rau theem pem hauv ntej yog electrostatic silicon suppressor SET thiab qhov tsis zoo clamp voltage suppressor NVCS, kom nqus tau thiab tso tawm lub zog loj. Cov cuab yeej tiv thaiv tom qab yog ib qho khoom tiv thaiv electrostatic ESD, nrog qhov tseeb clamp voltage thiab ceev cov tshuaj tiv thaiv ceev, nqus lub zog seem ntawm cov theem dhau los, txo qhov hluav taws xob mus rau hauv qhov ntau uas lub nraub qaum-kawg tuaj yeem tiv taus, thiab tiv thaiv lub nraub qaum- kawg chip. Hauv kev tiv thaiv ib txwm muaj 48V fais fab mov, cov cuab yeej tiv thaiv ntau dua yog siv los txhim kho qib kev sim, uas nyob hauv lub ntim loj thiab muaj kev tswj tsis zoo ntawm cov hluav taws xob seem, uas ua rau muaj qhov tshwm sim ntawm qhov rov qab kawg nti puas. Vim li no, SPSEMI Instant Thunder Electronics tau tsim qhov tsis zoo clamp voltage suppressor NVCS series khoom tshwj xeeb rau POE (48V fais fab mov). Cov khoom no muaj tus nqi ntws loj thiab ntim me me, uas tau ntim rau hauv SMC. Hais txog kev tswj qhov hluav taws xob seem, nws yog li 20V qis dua li cov khoom siv TVS, uas tuaj yeem tiv thaiv cov nti rov qab kawg.

(2) IEC61000-4-5: 10/700us LEVELX: 6KV
Txoj Cai: Ob lub tswv yim saum toj no tau txais kev tiv thaiv ob theem. Cov theem pem hauv ntej yog qhov tsis zoo clamp voltage suppressor NVCS, uas absorbs thiab tso tawm lub zog loj. Cov cuab yeej tiv thaiv tom qab yog ib qho khoom tiv thaiv electrostatic ESD, uas muaj qhov tseeb clamping voltage thiab ceev cov tshuaj tiv thaiv ceev. Nws absorbs lub zog seem ntawm pem hauv ntej theem, txo qhov voltage kom nyob rau hauv qhov ntau uas lub nraub qaum-kawg Circuit Court tuaj yeem tiv taus, thiab tiv thaiv lub nraub qaum-kawg nti.
Raws li tus txheej txheem thoob ntiaj teb IEC61000-4-5, xob laim surge zog feem ntau yog txhaj rau hauv hom hom. Hauv kev tsim cov tswv yim, kev saib xyuas yog them rau kev tiv thaiv hom. Tus tiv thaiv electrostatic TUSD03FB yog ntxiv ntawm cov kab sib cais rau kev tiv thaiv kev sib txawv, tshem tawm cov khoom seem ntawm lub zog txuas mus rau sab nraub qaum thaum lub caij xob laim, thiab tiv thaiv lub siab sib txawv ntawm cov kab los ntawm kev hloov. Cov phiaj xwm tiv thaiv saum toj no tau raug txheeb xyuas los ntawm SPSEMI Transient Thunder Electronics Laboratory.
Cov saum toj no yog cov ntsiab lus luv luv ntawm POE Lub Hwj Chim dhau Ethernet Surge Protection, uas tuaj yeem ua tus siv rau txhua tus. Peb lub tuam txhab muaj ib pab neeg ua haujlwm muaj zog thiab tuaj yeem muab kev pabcuam tshaj lij rau cov neeg siv khoom. Tam sim no, peb lub tuam txhab muaj ntau yam khoom: ntseonu, Kev sib txuas lus Optical module, optical fiber module, sfp Optical module,olt uakhoom siv, Ethernethloovthiab lwm yam khoom siv network. Yog tias koj xav tau, koj tuaj yeem nkag siab tob.
