CR8450-2500-N

Overview

The CR8450-2500-N is a current sense transformer manufactured by CR Magnetics Inc., designed for non-invasive current monitoring applications. It features a solid core construction with a rated current of 75 A and a turns ratio of 2500:1. The device operates within a frequency range of 20 Hz to 1 kHz and exhibits a secondary DC resistance of 160 Ohms. It utilizes wire lead termination and is packaged in a free-hanging in-line configuration, allowing for direct integration into power lines without physical interruption.

Feature Summary

• Non-invasive solid core design enables current sensing without circuit interruption
• Free-hanging in-line package facilitates easy installation on conductors
• Wire lead termination provides flexible connection options for PCB or harness mounting

Applications

• Power supply current monitoring
• Motor drive protection circuits
• Industrial equipment fault detection

Procurement Notes

Verify the specific manufacturer part number against official CR Magnetics documentation to ensure compatibility with system requirements. Confirm that the 75 A rating and 160 Ohm secondary resistance align with the target application's electrical parameters. Check for any specific handling instructions regarding the wire leads and solid core structure during assembly.

Selection Notes

Select this component when a non-invasive solution is required for currents up to 75 A. Ensure the operating frequency falls within the 20 Hz to 1 kHz range. Consider the free-hanging form factor for space-constrained environments where chassis mounting is not feasible. Verify that the wire lead termination method matches the available connection infrastructure.

Part Context

This component belongs to the CR8450 series of current sense transformers from CR Magnetics Inc. The series offers various current ratings and turns ratios to suit different power levels. The CR8450-2500-N specifically targets higher current applications requiring precise isolation and signal fidelity within the specified low-frequency band.

Replacement Considerations

Direct substitutes must match the 75 A rating, 2500:1 ratio, 160 Ohm resistance, and in-line form factor. Cross-reference with other manufacturers' solid-core current transformers offering similar electrical specifications and mechanical dimensions.
