Socan Open loop current sensor SCK25 Series

Product catalog summary

Product Description
The SCK25 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 high isolation voltage of over 3000VAC between primary and secondary circuits and complies with the UL94-V0 flame retardant rating. The sensor can be installed in two ways: standing or lying.

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

Applications
The SCK25 sensor is suitable for use in inverters, UPS systems, 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.

Model Parameters
The SCK25 model is available in various primary current ratings from 600A to 2000A, with a maximum peak value of ±3000A for higher ratings.

Dimensions and Installation Notes
The sensor dimensions include a primary aperture of 64x22mm and fastening holes of φ5.5mm. The output terminals differ between models, with the K25 using Molex 5045-04AG and the K25T using 2EDGVC-5.08-4P. The primary conductor temperature should not exceed 105°C, and incorrect wiring may damage the sensor.

Socan Open loop current sensor SCK25 Series-1

Hall effect Current Sensor SCK25 Product description Features Based on Hall effect measurement principle, open loop circuit mode. The isolation voltage between primary and secondary is greater than 3000VAC. Comply with 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. Wide measurement range, fast response speed, low zero drift, low temperature drift, high accuracy and good linearity. Dynamic performance (di/dt and response time) is optimal when the busbar is fully filled with primary perforations. Strong ability to resist external electromagnetic interference (BCI, EFT, CS, CE, ESD, 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.
