Open-loop Hall effect current sensor / AC / DC 51*13mm, 600..2500 A | SCK34 series

Product catalog summary

Product Description
The SCK34 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 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 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 SCK34 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 sensor is available in various models with primary current ratings ranging from 600A to 2500A. It has a maximum peak current value of up to ±4500A and an output voltage of ±4V±1%. The input power supply voltage range is ±11 to ±18 VDC, with a current consumption of up to 20 mA. The sensor's accuracy is ±1% at 25°C, with a linearity of ±0.5% IPN. It operates within an ambient temperature range of -40°C to 125°C.

Dimensions and Notes
The SCK34 has specific dimensions with a primary aperture of 51x13mm and fastening holes of φ4.5mm. The output terminals differ between the SCK34 and SCK34T models. The primary conductor temperature should not exceed 105°C, and incorrect wiring may damage the sensor.
