三相单相防窃电智能电表晶振FA-20H爱普生EPSON石英无源晶振Q24FA20H0003900
对于三相智能电表可以采用同样的方法.在传统的四线系统中,零线被选作电表AFE的接地参考.相电流利用电流互感器测量.电源利用所有三相创建两个电源域：一个为AFE供电,一个为通信模块供电,电源必须进行隔离以保证安全.MCU可以置于任一电源域中,因此AFE与MCU之间（隔离1）或MCU与通信模块之间（隔离2）都存在一个隔离栅.与大型、昂贵、爱普生EPSON晶振难以通过认可的隔离电源相比,这种方法的优势显而易见.数字隔离技术造就了业界很小的UL认可DC-DC转换器,这些IC具有很高的热稳定性和机械稳定性、出色的耐化学腐蚀性以及良好的ESD性能.设计工程师现在可以集中精力改善系统设计,而无需担心隔离问题.三相单相防窃电智能电表IC内置芯片级变压器的单相防窃电智能电表.IC内置芯片级变压器的单相防窃电智能电表
