TDC-EA Sensor

TDC-EA 系列直流漏电流传感器

TDC-EA Series DC Leakage Current Sensor


TDC-EA 系列直流漏电流传感器是应用磁调制原理研制而成的一种新型电流传感器,其小电流的稳定性好,初级与次级之间高度绝缘,用于讯号系统、线路检测、漏电监测系统、电流差值测量。

TDC-EA series DC leakage current sensor is a kind of new device developed according to principle of electromagnetic induction. Its low current is stable, It is highly insulating between its primary coil and secondary coil, This sensor is used to measure current of signal system, circuit, and leakage monitoring system, as well as to measure current difference.
