SCB31 Series Close Loop Current Sensor

Product catalog summary

Product Description
The SCB31 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 features 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 exhibits very low temperature and 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 SCB31 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 SCB31 model is available in 100A and 200A versions, with a primary current max peak value of ±200A and ±300A, respectively. It has a turns ratio of 1:2000 and a secondary coil internal resistance of 76Ω at 70℃. The output signal is ±50mA for 100A and ±100mA for 200A. The input power supply voltage range is ±12 to ±18 VDC, with a current consumption of 13mA plus output current. The accuracy is up to ±0.8%, and the linearity is up to ±0.5%. The response time is 1 microsecond, and the bandwidth is 50 to 100K Hz. The operating temperature range is -40 to 85℃, and the storage temperature range is -40 to 90℃. The sensor can withstand a voltage of 3000VAC.

Dimensions and Notes
The dimensions are provided with a size error of ±0.5mm. The primary aperture and pinpoint output dimensions are specified, along with recommendations for PCB cut-out. The direction of the current is indicated, and incorrect wiring may damage the sensor.
