DC leakage current sensor - Weikewei - milliampere level measurable, factory direct sales

DC leakage current sensor is used to measure milliampere level DC current (AC) in a primary wire

直流漏电流传感器


58彩票And direct current (DC) components. This sensor uses "magnetic modulation" technology to compensate for the AC component in the primary conductor by introducing a bias magnetic field. The bias magnetic field is generated by an internal square wave oscillator, which balances the alternating current magnetic field of the main conductor.
