Closed-loop Hall effect current sensor SCB31

Product Details
SCB31 Series Close Loop Hall 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 waveforms current in electrical isolation conditions. Perforations in the form of a square type, use for copper connections, it is widely used in inverters, power supply, DC panel and welding machines etc.
