HAH1DRW 300-S/SP5

Current Sensors Overview

The HAH1DRW 300-S/SP5 is a Hall effect current sensor manufactured by LEM USA Inc. It features an open-loop, unidirectional design with a single pass-through configuration. The device provides one channel of output and is rated for a primary current of 300A. This module is designed for industrial applications requiring precise current monitoring within a compact form factor.

Current Sensors Feature Summary

• Utilizes Hall effect technology for non-contact current measurement
• Open-loop architecture ensures high linearity and fast response
• Unidirectional sensing capability for positive current flow detection
• Single pass-through mechanical design simplifies installation

Current Sensors Applications

• Industrial motor drive systems
• Power supply current monitoring
• Inverter control circuits
• Battery management systems

Current Sensors Procurement Notes

Verify the specific suffix SP5 against official LEM documentation to confirm pinout and mounting compatibility. Ensure the 300A rating aligns with peak load requirements rather than just continuous current. Cross-reference the datasheet revision date to guarantee support for latest thermal characteristics. Confirm availability through authorized distributors to avoid counterfeit components.

Current Sensors Selection Notes

Choose this model when unidirectional current sensing is sufficient for the application. The 300A rating suits medium-power industrial loads. Consider the single pass-through design for space-constrained PCB layouts. Verify isolation voltage requirements match system safety standards before integration into high-voltage environments.

Current Sensors Part Context

This component belongs to the HAH1DRW series from LEM, which offers various current ratings including 100A, 200A, and higher variants. The series is characterized by robust construction suitable for automotive and industrial sectors. The SP5 suffix typically denotes specific packaging or terminal configurations within the product family.

Current Sensors Replacement Considerations

Direct substitutes include other HAH1DRW variants with different current ratings such as HAH1DRW 100-S/SP5 or HAH1DRW 900-S/SP5 if current capacity needs adjustment. Ensure electrical parameters like sensitivity and offset voltage remain compatible with existing signal conditioning circuits.
