Current Sensors datasheet and documents for RA 2000-S/SP1
Current Sensors Overview
The RA 2000-S/SP1 is a unidirectional Rogowski coil current sensor manufactured by LEM USA Inc. It features a single channel design with a primary nominal current of 3000 A and a secondary output signal of 20 mA. The device utilizes a single pass-through configuration for conductor installation. This module is engineered for high-precision AC current measurement applications, providing reliable performance in industrial environments through its specialized Rogowski coil technology.
Current Sensors Feature Summary
- Unidirectional measurement capability using Rogowski coil technology
- Single channel architecture designed for specific circuit monitoring
- Single pass-through installation method for simplified integration
Current Sensors Applications
- Industrial power distribution systems
- Motor drive current monitoring
- Energy management equipment
Current Sensors Procurement Notes
Verify the exact part number suffix against official LEM documentation to ensure correct connector type and calibration specifications. Confirm that the application requires unidirectional measurement, as this model does not support bidirectional current flow. Cross-reference the 3000 A rating with system peak loads to prevent saturation or damage during transient events.
Current Sensors Selection Notes
Select this component when unidirectional AC current measurement up to 3000 A is required. The Rogowski coil design offers flexibility for large conductors compared to split-core alternatives. Ensure the host system can process the 20 mA secondary output signal appropriately. Consider thermal limits and mechanical mounting constraints associated with the single pass-through form factor.
Current Sensors Part Context
This sensor belongs to LEM's range of high-current measurement devices. The RA series specifically utilizes Rogowski coil principles for non-invasive current sensing. The SP1 suffix typically denotes specific packaging or connector configurations defined by the manufacturer. It serves as a critical interface between high-power circuits and control electronics.
Current Sensors Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult LEM technical support for direct equivalents or updated models within the RA series.
