CR8349-2000-D

Overview

The CR8349-2000-D is a current sense transformer from the CR8300 series by CR Magnetics Inc. It features a 75 A rated current and a 2000:1 current ratio. The device operates within a frequency range of 20 Hz to 1 kHz and has a DC resistance of 48 Ohms. Designed for through-hole mounting, it utilizes PC pin termination. The component measures 1.024 inches in length, 0.670 inches in width, and has a maximum installation height of 1.102 inches. It is classified as a DC immune model.

Feature Summary

• DC immune design for accurate measurement in circuits with DC offset
• Non-invasive solid core construction for safe current sensing
• Through-hole mounting with PC pin termination for reliable board integration

Applications

• Current monitoring in power supply units
• Protection circuits in industrial motor drives
• Energy metering systems requiring DC offset tolerance

Procurement Notes

Verify the specific suffix 'D' confirms the DC immune characteristic, as standard models may lack this feature. Confirm the package type is bulk and check for RoHS compliance status. Ensure the supplier provides valid origin documentation to guarantee authenticity. Cross-reference the part number with official manufacturer catalogs to avoid substitution errors with non-DC immune variants.

Selection Notes

Select this component when measuring AC currents superimposed with significant DC components. The 75 A rating suits moderate to high current applications. Verify that the operating frequency falls within the 20 Hz to 1 kHz range. Consider the physical dimensions for PCB layout constraints. Ensure the load impedance matches the transformer's output requirements for accurate signal transfer.

Part Context

This part belongs to the CR8300 series of current transformers. It shares the same form factor and mounting style as other models in the series, such as the CR8349-1000-N. The primary distinction is the DC immune capability and the specific current ratio. This series is designed for commercial and industrial applications requiring robust current sensing solutions.

Replacement Considerations

The CR8349-2000-F is a similar through-hole current sense transformer but lacks the DC immune feature. Substitution requires verifying if the application involves DC offset. Other series members may differ in current rating or frequency response. Always consult the datasheet for electrical compatibility before replacing.
