NAC-50-472

Power Line Filter Modules Overview

The NAC-50-472 is a single-phase power line filter from the Cosel NAC series, rated for 50 A at 277 VAC or 300 VDC. It features a high-attenuation design targeting common mode noise within the 150 kHz to 1 MHz frequency range. The unit utilizes a terminal block connection method and includes a line-to-ground capacitance code of -472, supporting an insulation voltage of 4,000 VAC.

Power Line Filter Modules Feature Summary

• High attenuation performance for common mode noise suppression between 150 kHz and 1 MHz
• Designed for use in 277 VAC factory distribution panels and building equipment
• Supports high insulation voltage up to 4,000 VAC between line and ground

Power Line Filter Modules Applications

• Factory distribution panels
• Building equipment
• Industrial electronic devices requiring stable DC power conversion

Power Line Filter Modules Procurement Notes

Verify that the specific application requires the -472 line-to-ground capacitance code, as this parameter directly influences the attenuation characteristics compared to other variants like -222. Confirm compatibility with 277 VAC systems and ensure the terminal block mounting style aligns with the enclosure design. Cross-reference official datasheets for precise dimensional constraints and derating curves under varying thermal conditions.

Power Line Filter Modules Selection Notes

Select the NAC-50-472 when high common mode noise attenuation is required in the 150 kHz to 1 MHz spectrum for single-phase circuits. Ensure the system operates within the 277 VAC / 300 VDC rating and 50 A current limit. Consider the -472 capacitance value specifically if it matches the required EMI filtering profile for the connected semiconductor components.

Power Line Filter Modules Part Context

This component belongs to the Cosel NAC series of general-purpose power line filters. The series is engineered to provide stable DC power for electronic devices by filtering AC input noise. The NAC-50-472 variant specifically addresses high-current applications in industrial and commercial infrastructure where robust noise suppression is critical for sensitive electronics.

Power Line Filter Modules Replacement Considerations

Direct substitutes within the same series include NAC-50-222 and NAC-50-683. Note that these alternatives utilize different line-to-ground capacitance codes, which results in distinct attenuation characteristics. Verify that the electrical performance of any replacement part meets the specific noise suppression requirements of the original design.
