Power line filter modules are an important tool in maintaining and improving the performance of devices in an electrical system. The NAH-06-681-D is a power line filter module designed to reduce noise and improve the overall performance of an electrical system. This article will discuss the application field and working principle of the NAH-06-681-D.

Application Field

The NAH-06-681-D is designed to provide ultimate protection to sensitive electronic devices against broadband common-mode noise. It is suitable for DC-DC power supply systems, AC-DC power supply systems, motor-driven systems, sensor systems, LED lighting systems, and other related systems. The device has metal oxide varistors protecting against transients, diodes with high oppositive voltage for protecting against fault currents, and non-inductive resistors that eliminates the inner magnetic field and its influence.

Working Principle

The NAH-06-681-D has three stages of filtering to ensure optimal performance and protection. The first stage is the EMI/RFI filter, which works to reduce electromagnetic interference (EMI) and radio frequency interference (RFI). This is done by adding capacitance, inductance, and resistance to the circuit, which together form a low-pass filter that attenuates high frequencies. The second stage is comprised of metal oxide varistors (MOVs), which serve to protect against transient voltages. The third stage is a capacitor filter for suppressing line-to-line noise. This is done by connecting a capacitor between two lines, which absorbs any high-frequency noises that might be present.

The NAH-06-681-D also has two shielding layers that protect the system from external interference. The first is a metal shielding layer, which provides a shield between the filter and the environment. The second is an RF shielding layer, which works to block out unwanted radio signals. All of this works together to provide ultimate protection against EMI and RFI noise, while also allowing for optimal performance of the electrical system.

Conclusion

The NAH-06-681-D is a power line filter module designed to reduce noise and improve the overall performance of an electrical system. It has three stages of filtering to ensure optimal performance and protection, as well as two layers of shielding to protect it from external interference. This device is suitable for a variety of applications, and is the perfect choice for keeping sensitive electronic devices safe and performing their best.
