正品備件DOLD IL5880 絕緣監(jiān)控模塊，用于單相或三相，AC0-500V交流不接地系統(tǒng)的對地絕緣阻抗故障監(jiān)控。上海銳譽為你提供

產品介紹

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不間斷電源及其它不接地（IT）交流電源系統(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)對地阻抗值小于設定值時，IL5880將輸出繼電器信號用于警示或反饋。

被測電壓系統(tǒng)：AC 0-500V

可調阻值設定范圍：5 ... 100 kΩ

供電方式：測量系統(tǒng)自取電，或者外部輔助供電

輸出：2副轉換觸點，其中一幅觸點可設置10 kΩ ... 5 MΩ預報警
