CR2550-Y

Overview

The CR2550-Y is a current sense transformer from the CR2550 series, manufactured by CR Magnetics Inc. It operates within a frequency range of 50Hz to 400Hz and utilizes a non-invasive solid core design for free hanging in-line mounting. This component serves as a remote current indicator, providing a visual indication of electrical current flow through an integrated LED display mechanism.

Feature Summary

• Provides visual indication of electrical current flow via integrated LED
• Utilizes non-invasive solid core design for safe current sensing
• Supports free hanging in-line mounting configuration

Applications

• Remote current monitoring systems
• Visual status indication in power distribution units
• Low cost current flow verification in industrial equipment

Procurement Notes

Verify that the specific suffix 'Y' corresponds to the intended variant configuration, as datasheets may list related models like CR2550-R with similar form factors but potentially different internal components or ratings. Confirm the operating frequency range matches the application requirements of 50Hz to 400Hz. Ensure the non-invasive solid core design aligns with the physical installation constraints of the target system.

Selection Notes

Select this component when a low-cost, visual method for indicating current presence is required without breaking the circuit. The non-invasive nature simplifies installation compared to shunt-based solutions. Consider the 50Hz to 400Hz operational bandwidth to ensure compatibility with the source frequency. The free-hanging in-line mount offers flexibility in placement relative to the conductor path.

Part Context

This part belongs to the CR2550 series of remote current indicators designed by CR Magnetics Inc. These devices are engineered to offer a cost-effective alternative for monitoring electrical current flow visually. The series typically includes variants optimized for different mounting or display needs while maintaining the core functionality of non-invasive current sensing.

Replacement Considerations

The CR2550-R is a documented variant within the same series. Verify if the R suffix denotes a specific difference in the LED configuration or housing material compared to the Y suffix before substitution.
