Product name :SCB1R Series Close Loop Current Transducer

product model:SCB1R-50A .. SCB1R-300A

Series: SCB1R
Ipn: 50 ~ 300A
Diameter: 20mm

Socan Technologies now have develop and manufacture three kinds of current transducer for battery management systems or electrical cars, electrical bus etc. These models now are available, they are SCB1R, SCB11R, SCK12R.


  1. SCB1R Series 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.
  2. Perforations in the form of a round hole type, use for cable connections, it is widely used in inverter, all kinds of power supply, DC panel and Welding machines and other equipments.
  3. Can withstand GB / T2423.11 acceleration 3m / s2, frequency 20 ~ 1000HZ, eight hours each axis test.
