Current Sensors Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to confirm exact output specifications and mounting configurations. Ensure that the required operating voltage and load conditions align with the datasheet parameters before procurement. Cross-reference the manufacturing date code to ensure component availability and compliance with current production standards.

Current Sensors Selection Notes

Select this model when three independent AC current channels are required within a single unit. The 20A rating defines the maximum input capacity per channel. Consider the 4-20mA output compatibility with existing control systems. Verify that the 50Hz to 400Hz frequency range matches the application's electrical environment requirements.

Current Sensors Part Context

This component belongs to the CR4480 series of average RMS AC current transducers. The series offers various input ranges and output options. The CR4480-20 specifically denotes the 20A input variant. It shares the solid core design and DIN rail or panel mount capabilities common to the family.

Current Sensors Replacement Considerations

Consult official substitution lists for equivalent three-channel current sensors. Verify that any alternative maintains the 4-20mA output and 24VDC supply requirements. Ensure the replacement supports the same 20A per channel rating and frequency range.
