SCB 11 Series Hall Close Loop Current Sensor is a new generation closed loop current sensor based on Hall effect principle, it can accurately measure DC, AC and pulse current and other various irregular waveform in electrical isolation conditions. Perforations in the form of a round hole type, use for wire connections, it is widely used in inverters, power supply, DC panel and welding machines etc. 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. Excellent circuit design, all products is 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.
