NAC-04-222-D

NAC-04-222-D is a type of power line filter module that helps to reduce harmful electromagnetic interference (EMI) and radio frequency interference (RFI) to the electronic and electrical systems.

This type of filter module is suitable for various operating environments, like consumer electronics, energy, automotive, military, defense, aerospace, automotive electronic control, industrial automation, medical, telecom base transceiver station, main control panel, motor drive units and other power supply applications.

The module consists of an EMI/RFI filter, an electrolytic capacitor and a capacitor network. The EMI/RFI filter is designed to reduce the noise from sensitive circuitry and reduce the threats of electromagnetic or radio frequency interference. The electrolytic capacitor is used to store charge and it can also act as a filter which can block the high frequency noise. The capacitor network provides the necessary circuit impedance to reduce the voltage ripples. The combination of the EMI/RFI filter, electrolytic capacitor and the capacitor network can filter out the noise better than if each component were used independently.

The NAC-04-222-D power line filter module is designed for power systems with input voltage up to 1000 VAC, frequency up to 10 kHz and dielectric strength up to 2500 VAC. It has a rated current of 10A and it can handle up to 15A peak load current. The ripple current specification is 2A. It comes with an EMI filter rating of 47dB and a RFI filter rating of 65dB. The frequencies range from 150Hz to 400kHz. The module has an IP rating of IP 40 and it is UL, cUL, CE, RoHS and TUV certified.

The working principle of this module is based on the combination of mechanical shielding,series capacitor,parallel inductor and resistor. It also uses LC circuits to create a low pass filter, which can effectively reduce voltage ripples. The series capacitor and inductor are used to reduce the high frequency noise and generate a low pass filter. The resistor is used to reduce the impedance or reactance of the signal. This will reduce the amplitude of the noise. All these components together will minimize the EMI and RFI noise from the system.

The NAC-04-222-D power line filter module is a popular choice for many applications as it has a good EMI/RFI filter rating, high current handling capability and an IP rating for use in harsh environments. It is easy to install and use. It has a wide range of input voltage and frequency and can reduce both EMI and RFI noise from sensitive electronic systems.
