Closed-loop current sensor / DC /AC, Hall current Sensor SCB1 Series

Product catalog summary

Product Description
The SCB1 Hall Effect Current Sensor by Shenzhen SoCan Technologies Co., Ltd is designed based on the Hall effect measurement principle and operates in a closed-loop circuit mode. It offers an isolation voltage greater than 3000VAC and complies with the UL94-V0 flame retardant rating.

Performance
The sensor can measure DC, AC, pulse, and various irregular waveform currents under isolation conditions. It features very low temperature drift, zero drift, fast response time, and good linearity with an accuracy of up to 0.1%. The dynamic performance is optimal when the busbar is fully filled with primary perforations, and it has a strong ability to resist external electromagnetic interference.

Applications
The SCB1 sensor is suitable for use in inverters, UPS, photovoltaic inverters, electric vehicle drives, high-frequency power supplies, and inverter welding machines.

Implementation Standards
The product adheres to several standards including GB/T 7665-2005, JB/T 7490-2007, JB/T 25480-2010, JB/T 9473-2020, and SJ 20792-2000.

Technical Parameters
The SCB1 model is available in various configurations with primary current ratings of 50A, 100A, 200A, and 300A. The maximum peak primary current ranges from ±100A to ±400A. The turns ratio varies from 1:1000 to 1:3000, and the secondary coil internal resistance ranges from 20Ω to 77Ω. The output signal is consistent across models at ±100mA.

Electrical data includes an input power supply voltage range of ±12V to ±18V, with a current consumption of 13mA plus output current. The accuracy at 25°C is up to ±0.8%, and the linearity is up to ±0.5%. The response time is 1 microsecond, and the bandwidth is between 50Hz and 100KHz. The sensor operates in ambient temperatures ranging from -40°C to 85°C and can be stored at temperatures from -40°C to 90°C.

Dimensions and Notes
The SCB1 and SCB1T models have specific dimensions with a primary aperture of φ20mm and fastening holes of φ4.5mm. The output terminals differ between models, with SCB1 using Molex 5045-04AG and SCB1T using 2EDGVC-5.08-4P. Incorrect wiring may cause damage to the sensor.
