Open-loop Hall effect current sensor / AC / DC, 100..500A | SCK33 series

Product catalog summary

Product Description:
The SCK33D is a Hall effect current sensor designed for PCB mounting. It features an open-loop circuit method and provides isolation voltage greater than 3000VAC. The sensor is compact, easy to install, and made from materials with good mechanical properties, including corrosion and heat resistance. It is designed according to UL94-V0 flame retardant standards.

Performance:
The sensor can measure DC, AC, pulse, and various irregular waveform currents under isolation conditions. It offers high measurement accuracy, fast response speed, low zero and temperature drift, and good linearity. The dynamic performance is optimal when the busbar is completely filled with the primary perforation. It also has strong resistance to external electromagnetic interference.

Implementation Standards:
The product complies with standards GB 7665, JB/T 7490, JB/T 9329-1999, JB/T9473-1999, and SJ/20792-2000.

Applications:
The sensor is suitable for AC frequency conversion speed regulation, servo motor traction, battery power, uninterruptible power supply, switching power supply, welding machine power supply, electric vehicles, and new energy sources such as photovoltaics.
