Current Sensors datasheet and documents for LF 1010-S/SP31
Current Sensors Overview
The LF 1010-S/SP31 is a closed-loop Hall effect current transducer designed for the electronic measurement of DC, AC, and pulsed currents with galvanic isolation. It features a nominal primary current (Ipn) of 1000 A RMS and a secondary output sensitivity of 0.2 mA/A. The device offers an overall accuracy of ±0.4% within the temperature range and a typical offset drift of 0.1% of Ipn. It operates on a dual supply voltage of +/- 15 to +/- 24 V, with a maximum response time of less than 0.5 μs. The sensor supports a bandwidth up to 200 kHz and functions within an operating temperature range of -40°C to +85°C.
Current Sensors Feature Summary
- Utilizes closed-loop ASIC-based Hall effect technology for high-precision fluxgate-level performance.
- Provides galvanic isolation between primary and secondary circuits for safe electrical measurement.
- Features a compact design suitable for various panel mounting configurations.
- Delivers fast dynamic response with minimal signal delay for accurate pulse current tracking.
Current Sensors Applications
- Variable speed drives for industrial motors
- AC/DC converters and power supplies
- Uninterruptible power systems (UPS)
- Battery management in electric vehicles
Current Sensors Procurement Notes
Verify the specific suffix SP31 against official LEM documentation to confirm pinout and mechanical compatibility. Ensure the procurement source provides valid manufacturer traceability. Confirm that the unit matches the specified 1000 A nominal rating and dual supply requirements before integration into the final assembly.
Current Sensors Selection Notes
Select this model when precise measurement of high-current AC, DC, or pulsed signals is required. The 1000 A nominal rating suits heavy-duty industrial loads. Consider the dual supply requirement and the 40x13 mm aperture size during PCB layout and enclosure design. Verify thermal management capabilities given the -40°C to +85°C operational range.
Current Sensors Part Context
The LF 1010-S series belongs to LEM's family of closed-loop Hall effect sensors. These devices are engineered for robust performance in demanding environments. The SP31 variant denotes specific packaging and terminal configuration options within the broader LF 1010 product line, maintaining consistent electrical characteristics across the series.
Current Sensors Replacement Considerations
Direct substitutes include other LEM closed-loop Hall sensors with similar 1000 A ratings, such as the LF 1005-S series, provided mechanical apertures and pinouts align. Cross-reference datasheets for exact sensitivity and supply voltage compatibility before substitution.
