CR2SFT-500

Current Sense Transformers Overview

The CR2SFT-500 is a commercial-grade AC current transformer manufactured by CR Magnetics Inc. It features a solid core design with an internal diameter of 1.13 inches and chassis mounting capabilities. The device supports an input range of 0 to 50 AAC and provides a corresponding output range of 0 to 5 AAC. It operates within a frequency band of 50Hz to 400Hz and includes two #8-32 terminals for connection.

Current Sense Transformers Feature Summary

• Non-invasive solid core construction for direct wire passage
• Chassis mount configuration with dual terminal connections
• Operational capability at ultra-low frequencies down to 20 Hz

Current Sense Transformers Applications

• Current sensing in power monitoring systems
• Industrial control circuit feedback loops
• Electrical protection relay inputs

Current Sense Transformers Procurement Notes

Verify the specific datasheet version from CR Magnetics Inc. to confirm insulation voltage ratings and terminal specifications. Ensure the mounting hardware matches the chassis requirements. Cross-reference the 50A input rating with actual system loads to prevent saturation. Confirm the 50Hz to 400Hz frequency range aligns with the application's operational spectrum before finalizing procurement.

Current Sense Transformers Selection Notes

Select this component when a non-invasive current measurement solution is required for AC circuits up to 50 Amperes. The 1.13-inch aperture accommodates standard cable sizes without modification. Consider the chassis mount style if panel integration is preferred over PCB mounting. Verify that the operating frequency falls within the specified 50Hz to 400Hz range for accurate signal transformation.

Current Sense Transformers Part Context

This part belongs to the CR2 series of current transformers from CR Magnetics, designed for commercial grade applications. The series emphasizes low-cost, high-volume styles suitable for general industrial use. The CR2SFT-500 specifically addresses the need for robust, solid-core current sensing in environments where invasive shunt resistors are impractical.
