CR8350-2500-N

Overview

The CR8350-2500-N is a current sense transformer from the CR8300 series by CR Magnetics Inc. It features a non-invasive solid core design with a current ratio of 2500:1 and a rated current of 100 A. The device operates within a frequency range of 20Hz to 1kHz and has a DC resistance (DCR) of 57 Ohms. It utilizes PC pin termination for through-hole mounting, with maximum dimensions of 1.535 inches in height.

Feature Summary

• Non-invasive solid core construction for direct conductor insertion
• High isolation capability suitable for power monitoring applications
• Through-hole PC pin termination for reliable PCB integration

Applications

• Industrial motor drive current monitoring
• Power supply output current sensing
• Inverter and converter protection circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to ensure correct packaging and tolerance specifications. Confirm that the application environment remains within the specified 20Hz to 1kHz frequency range to maintain accuracy. Check RoHS3 compliance status if environmental regulations apply to the final assembly. Ensure mechanical clearance accommodates the 1.535-inch seated height for proper installation.

Selection Notes

Select this component when a high-current rating of 100 A is required with a precise 2500:1 transformation ratio. The solid core design eliminates the need for split cores, simplifying installation on busbars or thick cables. Consider the 57 Ohm secondary resistance for burden resistor calculations. This model is appropriate for systems where through-hole mounting provides superior mechanical stability compared to surface mount alternatives.

Part Context

This part belongs to the CR8300 series of current sense transformers, designed for robust industrial environments. The series emphasizes high linearity and wide dynamic range for accurate current measurement. CR Magnetics utilizes specialized winding techniques to minimize phase shift and amplitude error across the operating bandwidth, ensuring reliable performance in demanding power electronics applications.

Replacement Considerations
