Remark:
1. DC leakage current sensor adapt non-contact measurement, it is develop on the basis of the principle of zero magnetic flux modulation and magnetic modulation, it can measure small DC current mA level’s isolation in perforation measurement.
2. Zero position output of the sensor output can be adjusted according to user needs.
3. We can customize different current and voltage output according to user's requirements.
SCD Series DC leakage current sensor is a new closed-loop current sensor developed from the application of magnetic modulation principle, excellent stability in tiny currents measurement, with a highly galvanic isolation between primary and secondary circuit. Widely used in leakage monitoring systems, signaling systems and the current difference measurement etc. Compare to other products, it’s small size, good linearity, high immunity to external interference, and has power-down protection and polarity protection. Imported electronic components assembled along with excellent circuit design, all products processed via 48 hours room temperature aging and eight hours high temperature aging, strict temperature drift and zero drift detection and control, it has excellent characteristics with long-term stable operation even in harsh working conditions. Potting by imported resin, this product has good thermal and insulating properties. It is well recognized and trusted by our domestic and foreign customers.
