Open-loop Hall effect current sensor / AC / DC, Split core ø40mm, 200..2000A | SCY7series

Product catalog summary

Product Description
The Split Core Hall Effect Current Sensor SCY7 by Shenzhen SoCan Technologies is based on the Hall effect measurement principle and operates in an open loop circuit mode. It features an isolation voltage greater than 3000VAC between primary and secondary circuits and is designed for easy installation without disassembling the busbar. The product 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
This sensor is suitable for use in communication power supplies, UPS systems, photovoltaic inverters, electric vehicle drives, and other products.

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.
