HAH1DRW 700-S/SP5

Current Sensors Overview

The HAH1DRW 700-S/SP5 is a unidirectional Hall effect current sensor module from LEM USA Inc. It features a single channel with a primary nominal current of 700 A and a maximum measurement range up to 1500 A. The device operates on a supply voltage of 4.75 V to 5.25 V, drawing a maximum supply current of 25 mA. It exhibits a response time of 6 µs and functions within an operating temperature range of -40°C to 125°C. The sensor utilizes an open-loop architecture for industrial current sensing applications.

Current Sensors Feature Summary

• Unidirectional current detection using Hall effect technology
• Open-loop module design for single pass-through installation
• Wide operating temperature range suitable for harsh environments

Current Sensors Applications

• Industrial current monitoring systems
• Power electronics protection circuits
• Motor drive current feedback

Current Sensors Procurement Notes

Verify the specific suffix SP5 against official LEM documentation to confirm pinout and mounting compatibility. Ensure the supply voltage remains within the 4.75 V to 5.25 V range to maintain specified accuracy. Confirm that the application requires unidirectional sensing, as this model does not support bidirectional current flow.

Current Sensors Selection Notes

Select this component when a unidirectional current measurement up to 700 A nominal is required. The low supply voltage requirement of approximately 5 V simplifies integration with standard logic-level controllers. Consider the 6 µs response time for dynamic load applications where faster switching sensors might be necessary.
