Open loop current sensor SCK12 Series

Product catalog summary

Product Description:
The SCK12 Hall effect current sensor by Shenzhen SoCan Technologies Co., Ltd is designed for measuring DC, AC, pulse, and various irregular waveform currents. It operates on the Hall effect measurement principle using an open loop circuit method and offers an isolation voltage greater than 3000VAC. The sensor is designed according to the UL94-V0 flame retardant rating and can be installed in two different methods: standing and lying.

Performance:
The sensor provides high measurement accuracy, a wide range, fast response speed, low zero drift, low temperature drift, small overshoot, and good linearity. It performs best when the busbar is completely filled with the primary perforation and has strong resistance to external electromagnetic interference.

Applications:
The SCK12 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 complies with several standards including GB/T 7665-2005, JB/T 7490-2007, JB/T 25480-2010, JB/T 9473-2020, and SJ 20792-2000.

Hall effect Current Sensor SCK12 Product description： Features Based on the Hall effect measurement principle, open loop circuit method. The isolation voltage between primary and secondary is greater than 3000VAC. Designed according to UL94-V0 flame retardant rating. Standing and lying two installation methods. Performance It can measure DC, AC, pulse, and various irregular waveform currents of cable conductors under isolation conditions. High measurement accuracy, wide range, fast response speed, low zero drift, low temperature drift, small overshoot, and good linearity. The dynamic performance (DI/DT and response time) is the best when the busbar is completely filled with the primary perforation. Strong ability to resist external electromagnetic interference (ESD, EFT, CS, CE, BCI, dv/dt, etc.). Application It can be widely used in inverters, UPS, photovoltaic inverters, electric vehicle drives, high-frequency power supplies, inverter welding machines and other products.
