Current Sensors Procurement Notes

Verify the specific suffix designation when ordering, as variants such as HAH1DRW 900-S/SP5 exist within the product family. Confirm that the required accuracy of ±3.25% and the 5V supply requirement align with your system specifications. Ensure the chassis mount interface matches your mechanical assembly constraints before finalizing procurement.

Current Sensors Selection Notes

Select this component for applications requiring unidirectional current sensing up to 900A. The open-loop Hall Effect principle offers a balance of performance and cost. Consider the ±3.25% accuracy tolerance and the -40°C to 125°C operating range to ensure compatibility with your thermal environment. Verify that the single-channel output meets your signal processing requirements.

Current Sensors Part Context

This part belongs to LEM's industrial current sensor lineup, designed for robust performance in demanding electrical environments. The HAH1DRW series utilizes Hall Effect technology to provide isolated current measurement. This specific model focuses on high-current unidirectional applications, distinguishing it from bidirectional or lower-range alternatives within the manufacturer's catalog.

Current Sensors Replacement Considerations

The HAH1DRW 900-S/SP5 is a documented variant within the same product family. When substituting, verify if the SP5 suffix denotes any functional differences or packaging changes. Ensure that any replacement maintains the 900A rating, 5V supply, and chassis mount form factor.
