Product name :SCK25 Hall-Effect Open Loop Current Sensor

product model:SCK25-200A .. SCK25-2000A

Series: SCK25
Ipn: 200A~2000A
Window: 64*22mm

SCK25 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 cooper connections, it is widely used in inverter, all kinds of power supply, DC panel and 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, it has excellent characteristics with long-term stable operation even in harsh working conditions.
