Type A: Dual pins, usually smaller in size and smaller in current range, usually using ultra-fine crystal cores with higher precision;  Type B: Four-pin parallel pins, usually the current is from large to small, usually using ultra-microcrystalline iron core, so the accuracy is higher;  Type C: Front and rear parallel pins, usually the current is from large to small, usually using ultra-microcrystalline iron core, so the accuracy is higher;  Class D: Three-pin, usually use silicon steel wound core, so the accuracy is not as good as the ultra-microcrystalline core, but the load capacity is strong.
A類:雙針腳,通常尺寸較小,電流范圍也小,通常使用超微晶鐵心,精度較高;

典型應(yīng)用

使用方法一:
典型應(yīng)用電路如圖1所示。二次負(fù)載基本為0?;ジ衅鲬?yīng)選用0負(fù)載互感器。通過(guò)運(yùn)算放大器,用戶可以調(diào)節(jié)反饋電阻R值在輸出端得到所要求的電壓輸出。而電容C及電阻r是用來(lái)補(bǔ)償相位差的。如用戶使用軟件補(bǔ)償或不需要補(bǔ)償相位差的場(chǎng)合,電容C及電阻r可以不接。圖中運(yùn)算放大器為通用運(yùn)算放大器;圖1中反饋電阻R的精度與輸出電壓的精度要求有關(guān);D1、D2二極管為1N4148起保護(hù)用,可以不接;C0為抗干擾電容,電容根據(jù)的電路及運(yùn)放技術(shù)參數(shù)來(lái)定,否則會(huì)引起輸出信號(hào)振蕩。

使用方法二:
典型應(yīng)用電路如圖2所示。并電阻R直接可以得到輸出電壓。V0=R*I0;R建議使用推薦值,太高容易飽和。圖2中C可以起到一定的相位補(bǔ)償作用,無(wú)相位要求可以不加 。
未找到相應(yīng)參數(shù)組,請(qǐng)于后臺(tái)屬性模板中添加
