ATO-100-B225-D16

Current Sense Transformers Overview

The ATO-100-B225-D16 is a current sense transformer manufactured by LEM USA Inc., designed for chassis mounting. It features a split-core construction to facilitate installation around primary conductors without disconnecting the circuit. The device is rated for an input current of 100 A and operates within a frequency range of 50 Hz to 60 Hz. It provides a voltage output ratio of 225 mV at the rated primary current, ensuring accurate signal generation for monitoring applications.

Current Sense Transformers Feature Summary

• Split-core design allows non-intrusive installation on existing busbars or cables
• Chassis mount configuration ensures secure physical positioning in control panels
• High accuracy performance with low phase shift characteristics for reliable measurement

Current Sense Transformers Applications

• AC/DC converter systems
• Industrial power supply monitoring
• Motor drive current sensing

Current Sense Transformers Procurement Notes

Verify that the specific part number matches the required 100 A rating and 225 mV output specification. Confirm the chassis mounting style aligns with panel layout requirements. Ensure the operating frequency range of 50 Hz to 60 Hz meets system standards. Check for RoHS compliance status if environmental regulations apply to the project.

Current Sense Transformers Selection Notes

Select this component when a split-core solution is necessary for retrofitting or maintenance-friendly installations. The 100 A rating suits medium-power industrial loads. Consider the chassis mount form factor for fixed panel integration rather than DIN rail or PCB mounting scenarios. Validate that the 225 mV output interface is compatible with downstream signal conditioning electronics.

Current Sense Transformers Part Context

This model belongs to the ATO series of current sense transformers from LEM USA Inc., which specializes in electrical parameter measurement sensors. The series includes variants with different current ratings such as 60 A and 125 A, all sharing similar split-core and chassis-mount architectures for consistent application integration across various power levels.

Current Sense Transformers Replacement Considerations

Direct substitutes include other models within the same ATO series, such as the ATO-60-B225-D16 or ATO-125-B225-D16, provided the current rating adjustment is acceptable for the specific application load.
