LT 2005-S/SP12

Current Sensors Overview

The LT 2005-S/SP12 is a closed-loop Hall effect current sensor designed for precise electronic measurement of DC, AC, and pulsed currents. It features a primary rated current of 2000 A and a secondary rated current of 10 mA. The device provides galvanic isolation between the primary high-voltage circuit and the secondary control circuitry. It utilizes a single pass-through primary connection method with a through-hole configuration. The module operates as a bidirectional current transducer within a single channel architecture.

Current Sensors Feature Summary

• Closed-loop Hall effect technology ensures high accuracy and linearity
• Galvanic isolation separates primary and secondary circuits
• Bidirectional measurement capability for diverse current types

Current Sensors Applications

• Electronic measurement of direct current
• Electronic measurement of alternating current
• Electronic measurement of pulsed current

Current Sensors Procurement Notes

Verify the specific suffix SP12 against official LEM documentation to confirm pinout and connector compatibility. Ensure the procurement specification matches the required 2000 A primary rating. Confirm that the closed-loop Hall effect design aligns with system isolation requirements. Cross-reference the secondary output current of 10 mA with downstream signal conditioning circuits. Validate the single pass-through mechanical dimensions for enclosure integration.

Current Sensors Selection Notes

Select this component when measuring high-current applications up to 2000 A requiring strict galvanic isolation. The closed-loop topology offers superior performance compared to open-loop alternatives for dynamic loads. Consider the bidirectional nature if reverse current flow occurs in the application. Verify that the through-hole mounting style fits the PCB layout constraints. Ensure the operating environment supports the thermal characteristics of the module.
