Instructions
1. SCK18 Series is open-loop current sensor. There is galvanic isolation between primary and secondary circuit of the sensor, it can measure DC, AC or pulse currents.
2. Big square perforation, mainly measure cooper conductor current.
3. Features: High accuracy, low power consumption, high liability and strong overload capacity.
