          JS7系列,是上海人民電氣有限公司 http://www.mauscontracting.com 為您提供的關(guān)于JS7系列型號,JS7系列價格,有關(guān)JS7系列的相關(guān)資料,上海人民電氣有限公司為你提供優(yōu)質(zhì)的產(chǎn)品,電話...

        產(chǎn)品介紹

        適用于交流50Hz,電壓至380V的電路中,通常用在自動或半自動控制系統(tǒng)中,按預(yù)定時間使被控制元件動作。

        符合JB/T54302標(biāo)準(zhǔn)。

        一些常見的型號有:JS7-1A,JS7-2A JS7-3A JS7-4A

        使用說明

        根據(jù)用戶使用需要,可調(diào)節(jié)進(jìn)氣孔通道的大小來得到不同的延時時間。即用螺絲刀旋轉(zhuǎn)銘牌中心之螺帽,往右旋得到的延時時間較短,反之則延時時間就長。

        該空氣式時間繼電器額定電壓380V,約定發(fā)熱電流3A,額定控制容量100VA。

        繼電器按其所具有延時的與不延時的觸頭的組成可分為如表所列4種型式:

        型號
        延時觸頭的數(shù)量
        不延時觸頭的數(shù)量
        重量KG
        線圈通電后延時
        線圈斷電后延時

        每種型號的繼電器尚可分類如下:

        1.按延時范圍可分0.4~60(s)和0.4~180(s)二種。

        2.按吸引線圈的額定頻率及電壓可分為:交流50Hz、24、36、110、127、220、380(A)六種。繼電器使用的環(huán)境溫度為+40℃~0℃當(dāng)施于繼電器的線圈的電壓為額定值的85%~110%時,繼電器能可靠工作。繼電器延時時間的連續(xù)動作重復(fù)誤差≤15%。繼電器允許用于操作頻率不大于600次/h和負(fù)載因數(shù)為40%的反復(fù)短時工作制及連續(xù)工作制。

        訂貨時,需指明繼電器的完整型號、名稱、延時范圍及其吸引線圈的頻率和電壓。舉例如下:

        JS7-2A普通型空氣式時間繼電器,延時范圍0.4~60S,50Hz,220V。
