IL5880.12 AC50-400HZ 220-240V 0053378

正品备件DOLD IL5880 绝缘监控模块，用于单相或三相，AC0-500V交流不接地系统的对地绝缘阻抗故障监控。上海锐誉为你提供

产品介绍

符合 IEC/EN 61 557

安装尺寸：30*90*61mm

应用场合：船舶电气自动化，输配电与发电二次保护，UPS不间断电源及其它不接地（IT）交流电源系统。

应用原理：时时监控不接地IT系统的对地绝缘阻抗，当系统对地阻抗值小于设定值时，IL5880将输出继电器信号用于警示或反馈。

被测电压系统：AC 0-500V

可调阻值设定范围：5 ... 100 kΩ

供电方式：测量系统自取电，或者外部辅助供电

输出：2副转换触点，其中一幅触点可设置10 kΩ ... 5 MΩ预报警
