L37S300D15J

Current Sensors Overview

The Tamura L37S300D15J is a board-mount current sensor module designed for precise DC current measurement. It utilizes an open-loop Hall effect sensing mechanism to detect currents up to 300A with a single channel configuration. The device operates on a 15V supply voltage and features a bidirectional output capability, allowing it to measure current flow in both directions. Key electrical specifications include a linear accuracy of ±1% and a fast response time of 3µs. The sensor draws a maximum supply current of 20mA and functions within a temperature range of -40°C to 85°C. It is housed in a module package suitable for base mounting.

Current Sensors Procurement Notes

Verify the specific suffix J against official Tamura documentation to confirm bidirectional functionality, as other variants in the L37S series may differ. Ensure the 15V supply requirement aligns with your system design. Confirm RoHS compliance status through the manufacturer's latest product list or datasheet before finalizing procurement plans.

Current Sensors Selection Notes

Select this model when bidirectional DC current sensing is required up to 300A. Compare against unidirectional variants if only positive current flow needs monitoring. Consider the module form factor for board space constraints. Verify that the 3µs response time meets the speed requirements of your control loop dynamics.
