SCD3-AC serials are close loop current sensors develops on the principle of magnetic modulation. Develop on base of magnetic modulation closed loop principle, apply unique patented technology, SCD3-AC Series measure tiny ac and dc leakage current (mA level from 10ma to 100ma).
1. Linear proportional relation between the output and primary leakage current arising from the primary conductors.
2. Hole size ø60mm designed, the biggest window of AC leakage sensor group.
3. High accuracy class 1.
4. Low current consumption less than ±20mA
5. Small thermal drift
Mainly applied for ground fault detection in Power supply system or measurement of tiny leakage current.
All SCD Series includes:
