SCK9 Series Hall Current Sensor is a new generation Open loop current sensor based on Hall effect principle, it could accurately measure DC, AC and pulse current and other various irregular waveforms current in electrical isolation conditions. Perforations in the form of a square hole type, use for copper connections, it is widely used in inverter, all kinds of power supply, DC panel, Welding machines and other equipments. Products potting adapt imported resin, which has excellent thermal conductivity and scalability. High-performance core result minimal residual magnetism, all electronic is imported components assembled, along with excellent circuit design, all products processed via 48 hours room temperature aging and eight hours high temperature aging, and by rigorous factory testing, it has excellent characteristics with long-term stable operation even in harsh working conditions. Good function in temperature compensation as well. Our products are deeply trusted and recognized by domestic and foreign customers.
