Open-loop Hall effect current sensor / AC / DC, 200..500A | SCK28 series

Product catalog summary

Product Description
The SCK28 Hall effect current sensor by Shenzhen SoCan Technologies Co., Ltd is designed based on the Hall effect measurement principle and operates in an open loop circuit mode. It features a single-chip programmable Hall IC compatible with automotive connectors, a working temperature range of -40°C to 125°C, and complies with the UL94-V0 flame retardant rating. The sensor is compact and easy to install.

Performance
The sensor can measure DC, AC, pulse, and various irregular waveform currents under isolation conditions. It offers a wide measurement range, fast response speed, low zero drift, low temperature drift, high accuracy, and good linearity. Optimal dynamic performance is achieved when the busbar is fully filled with primary perforations. It has strong resistance to external electromagnetic interference.

Applications
The sensor is suitable for use in electric vehicle drivers, battery management, and other related products.

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.
