NAC-20-472

Power Line Filter Modules Overview

The NAC-20-472 is a single-phase EMC/EMI line filter rated for 20 A and 250 VAC. It provides high attenuation of common mode noise within the frequency range of 150 kHz to 1 MHz. The unit features a capacitance value of 4.7 nF and utilizes a terminal block connection method. Physical dimensions are 2.09 x 1.62 x 3.63 inches. It holds certifications including UL, CSA, DIN, VDE, and ENEC under standards such as UL62368-1.

Power Line Filter Modules Feature Summary

• Provides high attenuation of common mode noise in the 150 kHz to 1 MHz range
• Designed for single-phase power line filtering applications
• Certified for international safety standards including UL, CSA, VDE, and ENEC

Power Line Filter Modules Applications

• Microprocessor-controlled power supplies requiring enhanced conducted noise attenuation
• General purpose industrial equipment noise suppression
• Single-phase AC power input stages in electronic systems

Power Line Filter Modules Procurement Notes

Verify that the specific application requires single-phase filtering with a 20 A current rating and 250 VAC voltage limit. Confirm compatibility with terminal block mounting methods. Ensure the system operates within the specified temperature and environmental conditions associated with the component's certification ratings. Cross-reference part numbers carefully as variants like NAC-20-472-D exist with different mechanical configurations.

Power Line Filter Modules Selection Notes

Select this component when standard filtering is insufficient for microprocessor-based systems. The 20 A rating suits moderate power applications. Verify space constraints against the 2.09 x 1.62 x 3.63 inch footprint. Consider the NAC-20-472-D variant if DIN rail mounting is required instead of standard chassis or panel installation methods.

Power Line Filter Modules Part Context

This component belongs to Cosel's NAC series of power line filters. These modules are designed to suppress electromagnetic interference in AC power lines. The series supports various current ratings and voltage specifications to accommodate different industrial and commercial power distribution needs.

Power Line Filter Modules Replacement Considerations

The NAC-20-472-D is a documented variant featuring DIN rail mounting capability. Verify mechanical fit and electrical specifications before substituting. No other direct cross-model replacements are confirmed in public documentation.
