Current Sensors Applications

• Battery chargers and battery management systems
• DC motor drives and control circuits
• Power supply management units
• Mobile applications requiring current monitoring

Current Sensors Procurement Notes

Verify that the specific part number matches the required input range of 50 A and the 4-20 mA output configuration. Confirm that the application environment remains within the specified 0°C to 50°C operating temperature limits. Ensure the power supply provides a stable 24 VDC source within the +/-10% tolerance to maintain accuracy. Check for any specific mounting requirements associated with the solid core housing design before finalizing the order.

Current Sensors Selection Notes

Select this component when a robust, gapless solution for DC current monitoring is required. The solid core architecture offers superior durability compared to split-core alternatives in fixed installations. Consider the 250 ms response time to ensure it meets the dynamic requirements of the target circuit. This model is suitable for general-purpose sensing where a standard 4-20 mA interface simplifies integration with existing instrumentation.

Current Sensors Part Context

This device belongs to the CR5220 series of DC current transducers from CR Magnetics Inc. The series includes variants with different input ranges, such as the CR5220-5 for 5 A and CR5220-150 for 150 A inputs. All models share similar operational characteristics, including the 24 VDC supply requirement and 4-20 mA output format, allowing for consistent system design across varying current scales.

Current Sensors Replacement Considerations

Direct substitutes include other CR5220 series models if the current rating differs, such as CR5220-5 or CR5220-150. Cross-brand replacements require matching the 4-20 mA output, 24 VDC supply, and solid core form factor. Verify that alternative components support the same 0-50 A input range and operate within the identical temperature specifications.
