Current Sensors datasheet and documents for LT 4000-S/SP22
Current Sensors Overview
The LT 4000-S/SP22 is a closed-loop Hall effect current sensor manufactured by LEM USA Inc. Designed for the electronic measurement of DC, AC, and pulsed currents, it provides galvanic isolation between the primary high-power circuit and the secondary control circuit. The device supports a primary current range up to 4000 A and features an output voltage range of 24 V to 24 V. It belongs to the LT series, which emphasizes high accuracy and reliability in industrial applications requiring precise current monitoring.
Current Sensors Feature Summary
- Closed-loop Hall effect technology ensures high linearity and precision
- Galvanic isolation separates primary power circuits from secondary control signals
- Capable of measuring DC, AC, and pulsed current waveforms
Current Sensors Applications
- Industrial motor drives and inverters
- Power supply systems requiring accurate current feedback
- Welding equipment with pulsed current requirements
Current Sensors Procurement Notes
Verify the specific suffix SP22 against the manufacturer's official datasheet to confirm pinout configuration and mechanical dimensions. Ensure the required primary current rating aligns with the 4000 A specification. Check for any updated revision notes or environmental compliance certifications prior to final procurement approval.
Current Sensors Selection Notes
Select this component when high-precision measurement of large DC or AC currents is required. The closed-loop design offers superior dynamic response compared to open-loop sensors. Consider the physical size and mounting requirements associated with the SP22 variant. Verify that the isolation voltage ratings meet the safety standards of the target application environment.
Current Sensors Part Context
This part belongs to the LT series of current transducers from LEM USA Inc., which are engineered for robust performance in demanding electrical environments. The LT 4000-S model represents a high-current capability within this family, suitable for heavy-duty industrial machinery. The SP22 designation indicates a specific packaging or terminal configuration distinct from other variants like SP32 or SP34.
Current Sensors Replacement Considerations
Direct substitutes include LT 4000-S/SP32 and LT 4000-S/SP34 from the same manufacturer. These alternatives share the same core sensing technology and electrical specifications but may differ in mechanical footprint or connector type. Cross-referencing the detailed mechanical drawings is essential before swapping these models.
