Surge Tiv Thaiv rau LED teeb pom kev zoo zog

Txawm li cas los xij, lub thev naus laus zis zoo nkauj no muaj qhov tseem ceeb tsis muaj zog: nws qhov kev hloov pauv mus hloov cov hluav taws xob uas tsim los ntawm xob laim lossis los ntawm lub zog hloov ua haujlwm ntawm AC network.

Vim tias nws qhov chaw tawg thiab qhov chaw dhau mus, lub teeb pom kev zoo ntawm LED teeb pom kev yuav ua rau muaj kev poob siab uas yuav tsim kev tsis ua haujlwm ntawm nws lub zog, kev puas tsuaj rau LED cov khoom lossis poob ntawm lub teeb pom kev zoo. Vim li no, siv qhov yuav tsum tau tiv thaiv kev tiv thaiv hluav taws xob nyob hauv cov hluav taws xob sab hauv LED teeb pom kev zoo.

LSP muaj cov neeg tiv thaiv mob uas tsim los txhim kho ntawm cov ntsiab lus sib txawv ntawm cov teeb pom kev zoo xws li cov teeb pom kev zoo, cov hauv paus ntoo, thiab cov txee rau hauv txoj kev.

LED Lights Surge Protection Device SLP10-320 series thiab SLP20-320 series thermally tiv thaiv Surge Protective Device yog cov cuab yeej tiv thaiv tus kheej tshwj xeeb tsim los siv rau sab nraum zoov thiab kev lag luam LED teeb pom kev zoo rau kev tiv thaiv overvoltage.

Nws tau tsim nrog LSP's thermally tiv thaiv varistor tshuab.

Nws muaj qhov ua haujlwm ntawm cov hluav taws xob tsis muaj hluav taws xob txuas ntxiv ua rau muaj kev tiv thaiv ntxiv kom tiv thaiv kev puas tsuaj loj thiab cov phom sij txawm tias muaj kev kub ntxhov ntawm cov huab cua hloov mus rau qhov kawg lossis muaj kev tiv thaiv zoo.

Lub LED Teeb Kev Tiv Thaiv Kev Tiv Thaiv Ntaus SLP10-320 series thiab SLP20-320 nta lub teeb tsa hauv LED uas ceeb toom thaum hloov pauv ntawm qhov xav tau.
