CR2550-W

Overview

The CR2550-W is a non-invasive solid core current sense transformer manufactured by CR Magnetics Inc. Designed for remote current indication, this component operates within a frequency range of 50Hz to 400Hz. It features a free-hanging in-line mounting type and includes a white LED for visual feedback. The unit achieves a full-on point at 0.75 AAC and has an inner diameter of 0.35 inches. Physical dimensions are approximately 1.094 inches in length.

Feature Summary

• Provides low-cost visual indication of electrical current flow via integrated white LED
• Non-invasive solid core design allows for easy installation without circuit interruption
• Optimized for operation across standard power frequencies from 50Hz to 400Hz

Applications

• Remote monitoring of AC current flow in industrial equipment
• Visual status indication in power distribution panels
• Current verification in motor control circuits
• Low-cost fault detection in electronic systems

Procurement Notes

Verify the specific suffix designation when ordering, as variants such as CR2550-R may differ in physical dimensions or housing color despite sharing similar electrical characteristics. Confirm that the required operating frequency aligns with the 50Hz to 400Hz specification. Ensure the target conductor fits within the 0.35-inch inner diameter aperture. Cross-reference the part number against official manufacturer documentation to confirm active status and availability before finalizing procurement plans.

Selection Notes

Select the CR2550-W when a simple, cost-effective method for visual current confirmation is required without complex signal processing. This component is suitable for applications where direct measurement is unnecessary, but presence of current must be visibly indicated. Consider the 0.75 AAC full-on threshold to ensure the LED activates appropriately for the expected load levels. Evaluate space constraints regarding the 1.094-inch length and free-hanging mounting style during system integration.

Part Context

This component belongs to the CR2550 series of remote current indicators produced by CR Magnetics Inc. The series focuses on providing economical solutions for monitoring electrical activity through visual means. These devices utilize solid core technology to detect magnetic fields generated by current-carrying conductors. The series is engineered for straightforward integration into various electrical assemblies requiring immediate visual feedback.

Replacement Considerations

The CR2550-R is a related variant within the same product family. While it shares the same frequency range and general function, verify dimensional compatibility and housing differences before substitution. Ensure any replacement maintains the required 0.35-inch ID and 50Hz-400Hz operational bandwidth.
