產(chǎn)品介紹

符合 IEC/EN 61 557

安裝尺寸：30*90*61mm

應用場合：船舶電氣自動化，輸配電與發(fā)電二次保護，UPS不間斷電源，電動汽車及充電樁，光伏逆變器及其它不接地（IT）直流電源系統(tǒng)。

應用原理：時時監(jiān)控不接地IT系統(tǒng)的對地絕緣阻抗，當系統(tǒng)對地阻抗值小于設(shè)定值時，IL5881將輸出繼電器信號用于警示或反饋。

被測電壓系統(tǒng)：DC 012-280V，DC 24-500V

可調(diào)阻值設(shè)定范圍：20 ... 500 kΩ

供電方式：測量系統(tǒng)自取電，或者外部輔助供電

輸出：2副轉(zhuǎn)換觸點
