Power Line Filter Modules are designed to filter out unwanted high frequency noise that are generated from other electrical devices. The NAC-20-332 is a three-phase AC line filter module, designed to eliminate any currents or voltages induced from nearby equipment that are above the rated frequency of the filter. This filter is commonly used in applications such as metering systems, communication systems, motor control circuits, electronic drives, and motor drives.

The working principle of the NAC-20-332 filter module is based on the concept of using capacitance and inductance to filter out high frequency signals. The module is composed of three stages of components: input signals from the power line, capacitors, and inductors. The input signals enter the filter module and are then passed through the capacitors, which act as a low pass filter. The capacitors reduce the amplitude of any high frequency signals, allowing the low frequency signals to pass through. These low frequency signals are then passed through the inductors, which act as a high pass filter. The inductors block out any low frequency signals that are present, allowing only the high frequency signals to pass through. The high frequency signals are then filtered out by the modules final stage, the output of the filter module.

The NAC-20-332 filter module is designed for use with systems that are expected to operate in temperatures ranging from -40°C to +85°C, and has a maximum operating voltage of 1000 VAC, making it ideal for use in harsh environments. It is also commonly used in industrial applications due to its ability to reduce electrical noise to less than 10% of the input signal. Additionally, the filter module is designed to meet the requirements of various international safety standards such as UL 94V-0, IEC 60529, CSA 22.2, EN 60721-3-3, IEC 60065, and IEC 60950.

The NAC-20-332 filter module is designed to reduce the amount of noise generated by electrical equipment, which can cause interference with other nearby devices. By using the capacitors and inductors, this filter module works by filtering out any high frequency signals that can cause interference, while allowing low frequency signals to pass through. This ensures that the power line remains free from interference and that the performance of the electrical devices is not degraded. The filter module is also designed to be able to withstand a wide range of temperatures, and meets international safety standards, making it an ideal choice for use in harsh industrial environments.
