NAP-04-332

Power Line Filter Modules Overview

The NAP-04-332 is a single-phase EMC/EMI power line filter module manufactured by Cosel USA, Inc. It is rated for a current of 4 A and operates at voltages up to 250 V AC or DC. The device features a single-stage filtering configuration with terminal block connections. Designed for chassis mounting, it supports an operating temperature range from -40°C to +85°C. The unit holds VDE certification and complies with RoHS standards.

Power Line Filter Modules Feature Summary

• Single-stage EMI/EMC noise suppression for AC and DC power lines
• Terminal block interface for secure electrical connections
• Chassis mount design for industrial integration
• Certified compliance with VDE safety standards

Power Line Filter Modules Applications

• Industrial control systems requiring EMI suppression
• Medical equipment power input stages
• General purpose electronic enclosures
• Automation machinery power supplies

Power Line Filter Modules Procurement Notes

Verify the specific suffix code against official Cosel documentation to confirm exact leakage current specifications and terminal type. Ensure the chassis mounting holes align with your enclosure design before purchase. Confirm that the 4 A rating meets your system's peak load requirements without derating issues under high ambient temperatures.

Power Line Filter Modules Selection Notes

Select this model when a compact, single-phase filter is required for low-current applications up to 4 A. Compare with the NAP-04-000 series if lower leakage current is critical, as the 332 suffix indicates specific attenuation characteristics. Ensure the terminal block style matches your wiring infrastructure. Verify voltage ratings match both AC mains and DC bus potentials in the target circuit.

Power Line Filter Modules Part Context

This component belongs to the Cosel NAP series of power line filters. The series offers various current ratings and attenuation levels. The NAP-04-332 specifically targets applications needing moderate noise reduction with standard terminal connectivity. It is part of a broader family including NAC and ESP series modules for different form factors and current capacities.

Power Line Filter Modules Replacement Considerations

Check for direct substitutes within the NAP-04 series with different suffixes for varied leakage currents. Cross-reference with the NAC series if DIN rail mounting is preferred over chassis mounting. Verify pinout compatibility before replacing existing units to avoid rewiring.
