HAX 1500-S/SP20

Current Sensors Overview

The HAX 1500-S/SP20 is a board-mount current transducer from the LEM HAX series, designed for high-current applications. It utilizes open-loop Hall effect technology to measure AC and DC currents with a nominal primary current of 1500A. The device provides an analog voltage output signal ranging from 0 to ±4V, corresponding to the measured current range. It operates on a dual supply voltage of ±15V and features a bandwidth extending up to 25 kHz. The sensor offers a measurement accuracy of 1% and has a typical response time of 5 µs. It is rated for operation within a temperature range of -40°C to +105°C.

Current Sensors Feature Summary

• Open-loop Hall effect technology enables precise measurement of both AC and DC currents without direct electrical contact with the primary circuit.
• Compact board-mount design facilitates integration into power electronics systems and industrial control boards.
• Analog voltage output provides a linear signal proportional to the primary current for easy interfacing with control circuits.

Current Sensors Applications

• Power supply systems requiring high-current monitoring
• Industrial motor drives and inverters
• Battery management systems in electric mobility

Current Sensors Procurement Notes

Verify the specific suffix SP20 against the official LEM datasheet to confirm pinout configuration and mechanical dimensions. Ensure the required ±15V dual supply is available for the application. Check for RoHS compliance status if environmental regulations apply. Confirm that the 1500A nominal current rating aligns with the peak load requirements of the target system to avoid saturation or damage.

Current Sensors Selection Notes

Select this model when high current capacity up to 1500A is required in a compact form factor. The open-loop architecture offers cost-effectiveness compared to closed-loop alternatives while maintaining sufficient accuracy for many industrial applications. Consider the 25 kHz bandwidth for dynamic load monitoring. Ensure the PCB layout supports the thermal dissipation needs given the operating temperature range up to 105°C.

Current Sensors Part Context

The HAX series represents LEM's line of board-mount current sensors designed for space-constrained applications. These sensors are part of a broader portfolio that includes various current ratings and technologies. The HAX 1500-S/SP20 specifically targets high-power applications where traditional through-hole sensors might be too large. It complements other LEM products like the HAS and HAT series, offering a specialized solution for board-level integration.

Current Sensors Replacement Considerations

Direct replacements may include other models within the LEM HAX series with different current ratings, such as HAX 500-S or HAX 2500-S, depending on the specific current requirement. Cross-series comparison with LTM or LTS models may be necessary if different mounting styles or technologies are preferred. Always verify electrical parameters and mechanical fit before substitution.
