    Kev Piav Qhia Luv:

    LW28 series universal transfer switches feem ntau yog tsim rau cov hluav taws xob circuits nrog AC qhuav 50Hz, rated ua haujlwm voltage 440V thiab qis dua, DC voltage 240V thiab qis dua, thiab rated tam sim no txog li 160A. Lawv yog siv rau kev sib txuas tes lossis kev txiav ntawm cov circuits rau kev tswj hwm lossis kev hloov pauv, nrog rau kev tswj hwm ncaj qha ntawm peb-theem asynchronous motors thiab rau kev tswj hwm thiab kev ntsuas circuit. Cov khoom no yog siv dav ua circuit tswj switches, kuaj cov khoom siv switches, lub cev muaj zog tswj switches, master tswj switches, thiab hloov-hloov switches rau hluav taws xob vuam tshuab.

    Kev Taw Qhia Txog Khoom

    • Cov khoom ua tau raws li cov qauv GB14048.3, GB14048.5, thiab EC60947-3, EC60947-5-1.
    • Cov hloov pauv LW28 series muaj ntau yam kev qhia tshwj xeeb, nrog rau qhov ntsuas tam sim no ntawm 10A, 20A, 25A, 32A, 63A, 125A, thiab 160A.
    • LW28 series cov keyboards yog cov yam ntxwv los ntawm qhov me me, ntau yam kev ua haujlwm, cov qauv me me, kev xaiv cov khoom siv zoo heev, kev rwb thaiv tsev zoo, kev ua haujlwm hloov pauv tau yooj yim, kev nyab xeeb thiab kev ntseeg siab, thiab cov qauv tshiab thiab kev ua qauv. Plaub hom keyboards, LW28-10, LW28-20, LW28-25, thiab LW28-32F, kuj muaj cov haujlwm tiv thaiv ntiv tes.
    • Cov hloov pauv LW28 series siv tau dav thiab yog cov khoom hloov tshiab thiab zoo tagnrho, uas tuaj yeem hloov cov LW2, LW5, LW6, LW8, LWI2, LWI5, HZ5, HZI0, HZI2 thiab lwm hom hloov pauv uas twb muaj lawm nrog rau cov hloov pauv hloov pauv ntawm cov khoom siv xa tawm.
    • LW28 series hloov derivatives muaj xws li padlock switches thiab lockable switches (63A thiab hauv qab). Uas siv tau ua lub hwj chim txiav tawm switches rau cov khoom siv tseem ceeb kom tiv thaiv kev ua haujlwm tsis raug thiab tswj kev ua haujlwm ntawm cov neeg ua haujlwm tsis raug cai.
    • Cov hloov pauv 20A txog 63A hauv LW28 series kuj tseem tuaj yeem nruab nrog lub tsev tiv thaiv (laus 65).

     

     

    Cov xwm txheej ntawm kev teeb tsa

    • Lub qhov hloov pauv tau teeb tsa nyob rau hauv cov xwm txheej ib puag ncig ntawm qib kev ua qias tuaj 3;
    • Nruab raws li cov lus qhia uas lub Hoobkas muab.

    Cov xwm txheej ua haujlwm ib txwm muaj

    • Qhov kub ntawm huab cua ib puag ncig yuav tsum tsis pub tshaj + 40 ° C, thiab nws qhov kub nruab nrab hauv 24 teev yuav tsum tsis pub tshaj + 35 ° C;
    • Qhov txwv qis tshaj plaws ntawm qhov kub thiab txias ntawm huab cua yuav tsum tsis pub tshaj -25 ° C;
    • Qhov siab ntawm qhov chaw teeb tsa yuav tsum tsis pub tshaj 2000m;
    • Thaum qhov kub siab tshaj plaws yog + 40 ° C, qhov av noo ntawm huab cua tsis pub tshaj 50%, thiab qhov av noo siab dua tuaj yeem tso cai ntawm qhov kub qis dua 90% ntawm 20 ° C. Yuav tsum muaj kev ntsuas tshwj xeeb rau qee lub sijhawm vim muaj kev hloov pauv ntawm qhov kub thiab txias.
