Open-loop Hall effect current sensor 30 * 40 mm, 300 - 2000 A | SCK18 series

Product catalog summary

Product Description:
The SCK18 Hall Effect Current Sensor by Shenzhen SoCan Technologies Co., Ltd. is designed using the Hall effect measurement principle with an open loop circuit method. It features a high isolation voltage of over 5000VAC between primary and secondary circuits and is constructed according to the UL94-V0 flame retardant rating. The sensor utilizes automatic adjustment technology for enhanced performance.

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 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 SCK18 sensor is suitable for use in inverters, UPS, photovoltaic inverters, electric vehicle drives, high-frequency power supplies, and inverter welding machines.
