CR8450-2000

Overview

The CR8450-2000 is a current sense transformer manufactured by CR Magnetics Inc., designed for non-invasive current monitoring in power electronics. It features a solid core construction with an inline mounting style, allowing it to be installed directly into the conductor path without breaking the circuit insulation. The device supports a primary current rating of 200 A and operates within a frequency range of 20Hz to 1kHz. It provides a current ratio of 2000:1, ensuring accurate signal transformation for downstream processing. The unit has a maximum height of 0.550 inches (13.97mm) and utilizes wire leads for termination.

Feature Summary

• Non-invasive solid core design for direct conductor insertion
• High current handling capability up to 200 A
• Inline mounting configuration for seamless integration
• Wide frequency response suitable for AC and pulsed signals

Applications

• Motor drive current monitoring
• Power supply feedback loops
• Industrial inverter protection circuits
• Energy metering systems

Procurement Notes

Verify the specific lead time and availability status through authorized distributors or the manufacturer's official channels before finalizing procurement plans. Confirm that the wire lead termination style matches your assembly requirements. Ensure compliance with RoHS directives if required by your project specifications. Cross-reference the part number CR8450-2000 with official datasheets to confirm electrical parameters match your system design needs.

Selection Notes

Select this component when high-current isolation and compact inline installation are required. The 2000:1 ratio suits applications needing precise step-down of large primary currents for sensing ICs. Consider the 20Hz-1kHz bandwidth for standard power line frequencies and switching converters. Evaluate mechanical constraints regarding the 13.97mm height and inline form factor against available board space or chassis mounting options.

Part Context

This part belongs to the CR8450 series of current sense transformers from CR Magnetics Inc., which specializes in magnetic components for power management. The series offers various current ratings and ratios to accommodate different power levels. These transformers are engineered for reliability in demanding industrial environments, providing galvanic isolation between high-voltage primary circuits and low-voltage secondary sensing circuits.

Replacement Considerations

Direct substitutes may include other models from the CR8450 series with compatible current ratings and ratios, such as the CR8450-1000 or CR8450-500, provided the current ratio and physical dimensions fit the application. Verify that alternative parts maintain the same inline mounting style and frequency response characteristics.
