FN2030B-20-06

Power Line Filter Modules

FN2030B-20-06 is a Power Line Filter Module designed to suppress conducted interference on cables connecting two pieces of equipment. It employs a filter module that uses one or more capacitors and inductors to create a notch pointing towards the common mode frequency of the system, thereby rejecting conducted interference coupled onto the power line.

FN2030B-20-06 can take any standard from 2 up to 68 A, while the rated current of its filter module is 20 A. The nominal voltage is 327 VAC. It has a DC resistance of 0.04 Ω and a common mode impedance range of 2-20Ω. This product is UL approved, CE Certified, VDE Certified, Rohs compliant and ISO9000/14000 certified. It is also designed with copper wire shielding and encapsulated epoxy coating in order to ensure excellent signal insulation and protection from environmental factors.

Application Field

FN2030B-20-06 is designed for electromagnetic interference suppression, in order to prevent critical electrical equipment from possible damage, either operational or electric. It can be used in a variety of industries, such as telecommunications, instrumentation, medical, automotive, aerospace, and military.

FN2030B-20-06 can be used as a single unit or as part of a group of power line filters, connected in parallel. It is suitable for applications where the load and source impedance are matched, and can also be used in a wide range of power supplies and power systems. The filter is effective over a wide frequency range up to 27 MHz, depending on the configuration.

Working Principle

The FN2030B-20-06 uses a combination of capacitors and inductors to create a notch on the amplitude response of the filter, such that at certain frequencies the filter will reject any common mode interference coupled onto the power line, while allowing normal signals to pass through.

The filter works on the principle that a single or multiple capacitors are connected in series to provide a low-pass filter at high frequencies, while an inductor is connected in parallel to provide a high-pass filter at low frequencies. The position and number of these components are carefully adjusted to create a notch at the combined common mode frequency of the system.

The FN2030B-20-06 also provides a high power line filtering capability, with low insertion loss and excellent damping in the event of over-voltages or over-currents. The filter is also designed with high vibration and shock resistance for use in industrial or military applications.
