Tus qauv BNC coaxial interface yog siv rau kev tiv thaiv xob laim ntawm SD coaxial video surveillance system.

Kev piav qhia txog khoom

Network SPD (Surge Protective Device) yog ib lub cuab yeej siv los tiv thaiv cov kab ke sib txuas lus los ntawm kev cuam tshuam hluav taws xob xws li cov hluav taws xob tam sim ntawd, cov hluav taws xob nce siab, thiab xob laim. Lawv feem ntau raug ntsia rau ntawm qhov kawg ntawm cov kab sib txuas lus kom tiv thaiv kev puas tsuaj los ntawm cov hluav taws xob ntau dhau rau cov khoom siv lossis cov kab ke rhiab heev.

Lub tshuab sib txuas lus muaj xws li cov xov tooj, cov kab ntaub ntawv, cov kab network, thiab lwm yam, uas feem ntau ntsib kev hem thawj los ntawm kev puas tsuaj ntuj tsim xws li xob laim, thiab yog li ntawd xav tau kev tiv thaiv tsim nyog. Lub luag haujlwm ntawm network SPD yog coj cov hluav taws xob tam sim ntawd uas tau qhia hauv lub tshuab sib txuas lus mus rau hauv av thaum nws mus txog qib txaus ntshai, txhawm rau tiv thaiv cov khoom siv los ntawm kev puas tsuaj.

Thaum txhim kho network SPD, nws yog ib qho tseem ceeb uas yuav tsum xaiv cov khoom uas haum rau cov yam ntxwv ntawm txoj kab sib txuas lus thiab ua raws li cov lus qhia ntawm cov chaw tsim khoom rau kev teeb tsa kom raug. Qhov no tuaj yeem ua kom ntseeg tau tias lub kaw lus sib txuas lus tuaj yeem tiv thaiv cov khoom siv tau zoo hauv cov xwm txheej tam sim ntawd xws li xob laim, ua kom muaj kev ruaj khov thiab kev ntseeg tau ntawm kev sib txuas lus.

Txheej Txheem Cej Luam Khoom

Feem ntau Network SPD muaj tus qauv RJ45 interface, uas yog tsim rau kev txuas cov kab network rau cov keyboards, chaw ua haujlwm, thiab ntau yam khoom siv sib txuas lus hauv network. Thaum muaj kev cuam tshuam hluav taws xob xws li hluav taws xob tam sim ntawd lossis xob laim nkag mus rau hauv kab network, network SPD sai sai coj cov kev cuam tshuam no mus rau hauv av kom tiv thaiv cov khoom siv txuas nrog lub network los ntawm kev puas tsuaj.

Thaum txhim kho lub network SPD, feem ntau nws raug ntxig rau hauv qhov nkag ntawm kab network kom tiv thaiv overvoltage los ntawm kev kis mus rau cov khoom siv txuas nrog. Qhov no tuaj yeem ua kom muaj kev tiv thaiv zoo ntawm cov khoom siv network hauv cov xwm txheej tam sim ntawd xws li xob laim, thiab txhim kho kev ruaj khov thiab kev ntseeg siab ntawm lub network.

Kev piav qhia txog khoom

Lub PHL-S series SPD yog ib lub cuab yeej tsim tshwj xeeb los tiv thaiv cov khoom siv hauv thaj chaw xws li cov transmitters, switches, frequency signals, cov khoom siv sib txuas lus, TC, RTD, thiab lwm yam. Nws tuaj yeem siv rau I/O, DCS, PLC thiab lwm yam khoom siv hauv chav tswj, uas feem ntau txuas nrog siv ob txoj hlua thiab peb txoj hlua. Yog li ntawd, yuav tsum muaj kev tiv thaiv zoo kom tiv thaiv kev cuam tshuam ntawm xob laim impulse voltage lossis kev ua haujlwm over-voltage.
