CR5220S-2

Current Sensors Overview

The CR5220S-2 is a closed-loop magnetic modulator current sensor manufactured by CR Magnetics Inc. It functions as a unidirectional module designed for DC current sensing applications. The device provides a proportional DC current output and is loop-powered, meaning it draws energy from the output current loop rather than requiring an external power supply. This configuration supports accurate average DC value measurement of direct current input waveforms.

Current Sensors Feature Summary

• Closed-loop magnetic modulation technology ensures high accuracy in non-contact DC current sensing
• Loop-powered operation eliminates the need for separate auxiliary power supplies
• Unidirectional design optimized for measuring positive DC current inputs

Current Sensors Applications

• DC current monitoring in industrial control systems
• Power supply feedback loops
• Battery management systems requiring precise average DC measurement

Current Sensors Procurement Notes

Verify that the specific part number CR5220S-2 matches the required unidirectional closed-loop specification. Confirm that the application circuit supports loop-powered operation, as this device derives power from the output signal line. Ensure compatibility with the target DC current range and check for RoHS compliance status if environmental regulations apply to the assembly process.

Current Sensors Selection Notes

Select this component when a non-contact, high-precision solution for unidirectional DC current measurement is required. The closed-loop architecture offers superior linearity compared to open-loop alternatives. Consider the loop-powered constraint, which simplifies wiring but requires careful attention to voltage drop across the load. This model is suitable for DIN rail or panel mount installations where space efficiency and reliability are priorities.
