HOYS 200-SW-0000

Current Sensors Overview

The HOYS 200-SW-0000 is an open-loop Hall effect current sensor manufactured by LEM USA Inc. It features a single channel design with bidirectional measurement capability and a primary nominal current (IPN) of 200A. The device utilizes a single pass-through configuration for conductor insertion. Key electrical specifications include an accuracy of 1.25% of IPN at 25°C and a measuring range extending up to 2.5 times the nominal current. The module offers low offset and gain drift characteristics, ensuring stable performance across operating conditions.

Current Sensors Procurement Notes

Verify the specific suffix SW against the official LEM datasheet to confirm pinout compatibility and mechanical mounting requirements. Ensure the selected variant matches the required insulation voltage and overvoltage category III rating for your specific installation environment. Cross-reference the package dimensions with your PCB layout to guarantee proper fitment.

Current Sensors Selection Notes

Select this model when a robust open-loop solution is preferred for cost-sensitive applications requiring moderate accuracy. The 200A rating suits medium-power industrial loads. Consider the 1.25% accuracy specification against tighter tolerance requirements; if higher precision is needed, evaluate closed-loop alternatives within the LEM portfolio. Verify thermal management needs based on the expected continuous load current.

Current Sensors Part Context

This component belongs to the HOYS Series, which comprises high-performance open-loop Hall-effect current sensors designed for accurate measurement of DC, AC, and pulsed currents. The series supports ratings from 100A to 560A, offering a scalable solution for various industrial power electronics applications where reliable current feedback is critical for system safety and efficiency.

Current Sensors Replacement Considerations

Direct replacements must match the 200A nominal current, open-loop topology, and single-channel bidirectional functionality. Verify that any substitute part maintains comparable accuracy (±1.25%) and fits the same mechanical footprint. Check for identical supply voltage requirements and output signal types to ensure circuit compatibility without redesign.
