Power Line Filter Modules

NAC-30-681-D power line filter modules are specifically designed to help reduce the amount of electrical disturbances or noise in an AC power line. They are designed to filter out undesired frequencies to eliminate interference that other electronic devices could experience. These modules are typically used in industrial control systems, digital signal processing, and digital communications systems.

Application Field

NAC-30-681-D power line filter modules are used in many industrial applications, including factory automation, robotics, food processing, mining, oil and gas extraction, and other areas where electromagnetic disturbance might otherwise disrupt data transmission or device operation. These filters are also well-suited for use in high-voltage powerlines, such as those powering energy generating, transformer, and transmission systems.

Working Principle

NAC-30-681-D power line filter modules operate on the principle of inductive reactive element coupled with capacitive reactance. The inductive element, often referred to as the filter\'s Primary Inductive Reactive Element, acts to reduce the voltage of the power line signal at high frequencies, and the capacitive element, often referred to as the filter\'s Secondary Capacitive Reactance Network, acts to reduce the current in the power line signal at low frequencies. Together, the two elements provide a dual-frequency response filter that suppresses both high and low-frequency disturbances.

To ensure optimum filtering performance, each filter module is designed with carefully selected component values to ensure the desired amount of filtering. For example, the capacitive reactance network typically includes a capacitance rating and a resistance value, while the inductive reactive element utilizes a high-quality inductor and its associated series/parallel resistor-capacitor values. By adjusting the component values, the filter can be tuned to reduce the unwanted frequencies from interfering with the desired ones.

NAC-30-681-D power line filter modules are equipped with various levels of filtering, for different system applications and needs. These filters also feature built-in surge protection, EMI suppression, and over-voltage protection to provide comprehensive protection for sensitive electronic components and sensitive data.

In addition, these modules are also available in a variety of sizes and configurations, to accommodate a wide range of industrial application needs. They are also designed for easy installation and operation, making them a cost-effective solution for industrial control systems.
