Open-loop Hall effect current sensor / AC / DC 41*12mm, 500..2000 A | SCK4 series

Product catalog summary

Product Description:
The SCK4 series is based on the Hall effect measurement principle and operates in an open-loop circuit mode. It features a high isolation voltage between primary and secondary circuits, exceeding 3000VAC, and complies with the UL94-V0 flame retardant rating.

Performance:
The sensor can measure DC, AC, pulse, and various irregular waveforms under isolated conditions. It offers a wide measurement range, fast response speed, low 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 SCK4 series 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.

Technical Parameters:
The SCK4 series offers various models with primary current ratings from 300A to 2000A. The maximum peak value for primary current ranges from ±900A to ±2400A. The output voltage is ±4V with a 1% tolerance. The input power supply voltage range is ±11V to ±18V, with a current consumption of up to 20mA. The sensor has a withstand resistance of 1000 MΩ at 500V DC and an output internal resistance of 102 Ω. The accuracy is ±1%, and linearity is ±0.5% IPN. The response time is between 3 to 5 microseconds.

Dimensions and Notes:
The SCK4 series dimensions include a primary aperture of 41.6mm x 12mm and fastening holes of φ4.5mm. The output terminals differ between models, with SCK4 using Molex 5045-04AG and SCK4A using JST B4B-XH-A. The primary conductor temperature should not exceed 105°C, and incorrect wiring may damage the sensor.
