Power Line Filter modules provide effective protection for power supply circuits against various electrical disturbances generated by switching operations, transients and other hazardous conditions. The NAP-04-000-D is a power line filter module that meets stringent electromagnetic compatibility (EMC) requirements, providing reliable and cost-effective protection for electronic systems. This document provides an overview of the application field and working principle of the NAP-04-000-D.

Application Field

The NAP-04-000-D is designed for a wide range of applications, including industrial, medical, commercial, and automotive systems. It is suitable for applications requiring EMC protection for AC power lines up to 250 VAC, and can provide up to 10 A of continuous current. The module can be used in various power supplies, including AC-DC converters, DC-DC converters, and AC-AC converters. It is also suitable for a range of power supply architectures, such as isolated power supplies, multiple outputs, and dc-dc converters.

Working Principle

The NAP-04-000-D operates by filtering out voltage surges, transients, and noise from the power supply circuit. It is designed with three components: an EMI filter, an over-voltage protection circuit, and a DC blocking circuit. The EMI filter is designed to filter out electromagnetic interference, a wide range of AC noise, and transient pulses. The over-voltage protection circuit provides thermal protection against overvoltage conditions, preventing malfunction of the power supply due to excessive voltage. The DC blocking circuit allows the module to reject low-frequency DC voltages and provide a voltage-free output for the connected circuit.

The NAP-04-000-D is designed for robust and reliable operation, providing up to 8 dB of differential and common-mode attenuation. The filter is also equipped with a return loss function, which helps reduce reflected noise. The module is capable of handling up to 10 A of continuous current, and is capable of withstanding high-capacity surge current.

Conclusion

The NAP-04-000-D is an effective power line filter module for applications requiring EMC protection. It is suitable for a wide range of power supply architectures, and offers up to 8 dB of differential and common-mode attenuation. Its over-voltage protection circuit provides thermal protection against overvoltage conditions, and its DC blocking circuit allows for a voltage-free output. The module can handle up to 10 A of continuous current, and is capable of withstanding high-capacity surge current. In short, the NAP-04-000-D is an ideal solution for providing reliable and cost-effective protection for power supply circuits against various electrical disturbances generated by switching operations, transients, and other hazardous conditions.
