RP225-20-4.7-QD

Overview

The RP225-20-4.7-QD is a single-phase, two-stage power line filter module manufactured by Astrodyne TDI. It features a chassis mount design with quick connect termination for secure installation. The unit is rated for 250 VAC and supports a continuous current of 20 A at 50/60 Hz operating frequencies. It incorporates a 4.7 nF capacitance value to manage electromagnetic interference. The component complies with UL, CSA, and EN standards, ensuring adherence to international safety regulations for industrial applications.

Feature Summary

• Dual-stage filtering architecture for enhanced noise attenuation
• Chassis mount configuration with quick connect terminals
• Compliance with UL, CSA, and EN safety standards

Applications

• Industrial machinery power conditioning
• Medical equipment EMI suppression
• General purpose single-phase power line filtering

Procurement Notes

Verify the specific datasheet version for the RP225-20-4.7-QD to confirm exact dimensional tolerances and terminal specifications before integration. Ensure that the mounting hardware supports the chassis mount style and that the circuit environment remains within the 250 VAC and 20 A ratings. Cross-reference compliance certificates such as UL and EN to meet regional regulatory requirements for the intended deployment location.

Selection Notes

Select this model when high-performance dual-stage filtration is required for single-phase systems handling up to 20 A. The quick connect interface simplifies assembly compared to soldered alternatives. Verify that the 4.7 nF capacitance aligns with leakage current limits for sensitive medical or commercial loads. Confirm chassis availability for proper thermal management and mechanical stability during operation.

Part Context

This component belongs to the RP225 series of surface filter units designed for robust electromagnetic compatibility. The series offers various current and capacitance configurations to suit different power levels. The RP225-20-4.7-QD specifically addresses higher current demands while maintaining effective noise reduction through its two-stage design, distinguishing it from single-stage counterparts in the broader product family.

Replacement Considerations

Direct substitutes include other RP225 series variants with matching 20 A ratings and quick connect interfaces, such as the RP225-20-0-QD or RP225-20-3.3-QD, provided capacitance differences are acceptable. Ensure any replacement maintains the same voltage rating and physical mounting dimensions to fit existing chassis enclosures without modification.
