1.SCK4 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.Square perforation, mainly measure cooper conductor current.
3.Features: High accuracy, competitive price, low power consumption and strong overload capacity.
Caution: Incorrect wiring may damage the sensor
