LTC 1000-SF/SP10

Current Sensors Overview

The LTC 1000-SF/SP10 is a closed-loop Hall effect current transducer manufactured by LEM USA Inc. It features a single pass-through module design with a primary nominal current of 1000A and a secondary output signal of 200mA. The device supports AC, DC, and pulsed current measurements. It operates on a supply voltage range of ±15V to 24V. The unit is rated for a maximum operating temperature of 85°C and a minimum of -40°C. Input voltage limits are specified between 14.25V and 25.2V.

Current Sensors Feature Summary

• Closed-loop Hall effect technology ensures high accuracy and linearity for bidirectional current sensing.
• Single pass-through module construction allows direct integration into busbar or cable systems.
• Capable of measuring AC, DC, and pulsed current waveforms simultaneously.

Current Sensors Applications

• Industrial motor drive control systems
• Power supply monitoring circuits
• Inverter and converter current feedback

Current Sensors Procurement Notes

Verify the specific suffix SP10 against official LEM documentation to confirm pinout and mechanical dimensions. Ensure supply voltage requirements match the ±15V to 24V specification. Confirm thermal management capabilities for the 85°C maximum operating temperature limit in the target application environment.

Current Sensors Selection Notes

Select this component when a 1000A nominal current rating is required for closed-loop measurement. The analog 200mA output interface suits applications needing direct current proportional signals. Consider the module form factor for space-constrained industrial enclosures requiring single-pass installation.

Current Sensors Part Context

This model belongs to the LTC series of current transducers from LEM. It shares the closed-loop Hall effect architecture with other models like the LTC 1000-SF. The SP10 suffix denotes specific packaging or connector variations within the product family.
