CR8448-2000

Overview

The CR8448-2000 is a current sense transformer from the CR Magnetics Inc. CR8400 series, designed for non-invasive AC current monitoring. It features a solid core construction with a 50 A current rating and a 2000:1 turns ratio. The device operates within a frequency range of 20 Hz to 1 kHz and exhibits a DC resistance of 106 Ohms. It utilizes wire leads for termination and supports free-hanging in-line mounting. The component measures 1.160 inches in length and 0.922 inches in width, providing a compact solution for industrial power sensing applications.

Feature Summary

• Non-invasive solid core design for safe AC current measurement
• High isolation capability suitable for general-purpose sensing
• Wire lead termination for flexible circuit integration

Applications

• Industrial motor drive current monitoring
• Power supply output current sensing
• General-purpose AC current measurement systems

Procurement Notes

Verify the specific manufacturer part number against official datasheets to ensure compatibility with system requirements. Confirm that the 2000:1 ratio and 106 Ohm DC resistance align with downstream signal conditioning circuits. Check for any suffix variations such as -F which may indicate packaging or material differences. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this component when a non-invasive current sensing solution is required for AC signals up to 50 A. The 20 Hz to 1 kHz frequency range makes it suitable for standard power line frequencies and low-frequency switching applications. Consider the 106 Ohm secondary impedance when designing the burden resistor network to maintain accuracy within the specified operating range.
