Current Sensors datasheet and documents for AHR 2000 B420
Current Sensors Overview
The AHR 2000 B420 is a split-core current transducer manufactured by LEM USA Inc. It utilizes Hall effect technology for open-loop, bidirectional measurement of AC, DC, and pulsed currents up to 2000A. The device provides an analog output signal ranging from 4 to 20mA. It operates with a supply voltage range of 20VDC to 50VDC and maintains an accuracy of ±1%.
Current Sensors Feature Summary
- Split-core design facilitates installation without disconnecting primary conductors
- Hall effect open-loop technology ensures precise measurement of complex waveforms
- Bidirectional capability allows detection of both positive and negative current flow
Current Sensors Applications
- Industrial motor drive monitoring
- Power supply current regulation
- Battery management systems in electric vehicles
Current Sensors Procurement Notes
Verify the specific suffix B420 against the official LEM datasheet to confirm pinout configuration and mounting style. Ensure the supply voltage matches the 20VDC to 50VDC requirement. Confirm RoHS compliance status if required by project specifications. Cross-reference the part number with authorized distributors to avoid counterfeit components.
Current Sensors Selection Notes
Select this component when high-current measurement up to 2000A is required without breaking the circuit. The split-core architecture is ideal for retrofitting existing installations. The 4-20mA output integrates easily with standard PLC or data acquisition systems. Consider the ±1% accuracy tolerance for precision applications.
Current Sensors Part Context
This model belongs to the LEM AHR series of current transducers. The series is designed for robust industrial environments requiring reliable current sensing. The AHR 2000 variant specifically addresses high-amperage applications where traditional shunt resistors would introduce excessive power loss or heat generation.
Current Sensors Replacement Considerations
Consult LEM technical documentation for direct cross-references. Verify that any substitute part matches the 2000A rating, split-core form factor, and 4-20mA output specification. Ensure compatibility with the 20-50VDC supply range.
