Current Sensors datasheet and documents for LA 25-NP/SP43
Current Sensors Overview
The LA 25-NP/SP43 is a closed-loop Hall effect current sensor manufactured by LEM USA Inc. It features a primary current rating of 25 A with a secondary turn ratio of 25:1000. The device operates within a frequency range of DC to 150 kHz and provides an output current proportional to the measured input. Key electrical specifications include a linearity of ±0.2%, accuracy of ±0.5%, and a response time of 1 µs. It requires a supply voltage of ±15 V and consumes a maximum supply current of 10 mA. The sensor supports bidirectional measurement for both AC and DC currents, ensuring high precision in industrial applications.
Current Sensors Feature Summary
- Closed-loop Hall effect technology ensures high accuracy and low temperature drift
- Optimized response time of 1 µs for fast dynamic signal detection
- Bidirectional capability allows precise measurement of both AC and DC currents
- High linearity of ±0.2% maintains signal integrity across the operating range
Current Sensors Applications
- Industrial motor drive control systems
- Uninterruptible power supply (UPS) monitoring
- Inverter and converter current feedback loops
- Railway traction system current sensing
Current Sensors Procurement Notes
Verify the specific suffix SP43 against the manufacturer's latest datasheet to confirm pinout compatibility and mechanical dimensions. Confirm RoHS compliance status and check for any recent product change notices affecting lead times or packaging. Ensure the ordering part number matches the required turn ratio and housing type for your PCB layout.
Current Sensors Selection Notes
Select this component when a 25 A primary current rating and 1 µs response time are required for closed-loop sensing. Consider the ±15 V dual supply requirement and 10 mA supply current for power budget calculations. Verify that the through-hole module package fits the available board space and thermal management constraints compared to surface-mount alternatives.
Current Sensors Part Context
This model belongs to the LA Series of industrial and railway current sensors from LEM USA Inc. The series is designed for high-performance applications requiring precise current measurement. The LA 25-NP variant specifically denotes the 25 A rating and standard housing, while the SP43 suffix indicates specific configuration details defined by the manufacturer.
