EMC-Filter

No line-conducted interferences due to the EMC filter

EMC filters are used for suppressing line-conducted interferences.

The spreading is prevented by a maximum level of impedance mismatch. The filtering effect extends in both directions. This means that both the interference from the consumer to the network and the interference from the network to the consumer are suppressed.

  • CNW 561/16

    PLC-Filter for DIN rail mounting

    CNW 561/16
    • Nominal Voltage: 250 V
    • Rated current: 16 - 25 A
    • Leakage current: <3,5 mA

    The PLC filters CNW 561/16 eliminate interference in applications in grids with ripple control technology or Powerline Communication (PLC).



    Due to the high-frequency PLC signal in the supply grid, interferences can occur in connected equipment. These interferences can lead to the following negative impacts:



    • Interference noise on the radio
    • Interference on televisions
    • Flickering lights
    • Slow network over mains



    Due to the additional use of the existing mains network, these transmission processes can be quickly and cost-effectively implemented.
    Of particular importance are the safety aspects and the resistance to interference.
    With the PLC filter, the signals of the ripple control and/or the Powerline Communication (PLC) can be filtered and blocked. The interfering signals are prevented from unwanted signal propagation. Due to PLC signals, electrical consumers such as LED lighting can experience interference.
    Furthermore, unshielded power cables behave like antennas and lead to increased emission of signals.



    The maximum interference level of cables that are used for telecommunication purposes is clearly defined by the provisions of use of the EC directive 89/336/EEC.
    REO PLC filters help to remain in compliance with EC directive 89/336/EEC and to reduce the interference level to a minimum.

  • CNW 562/16

    PLC-Filter for DIN rail mounting

    CNW 562/16
    • Nominal Voltage: 250 V
    • Rated current: 16 A
    • Leakage current: <3,5 mA

    The 562 single-phase PLC filter is designed for use in grids with ripple control technology.



    Data in the form of high-frequency ripple control signals is superimposed onto the line frequency of 50/60 Hz in the supply power grid.
    Ripple control signals are used for controlling smart meters in smart grids or devices such as street lights, night storage heating systems or tariff switching (off-peak electricity).



    These transmission processes can be very quickly and cost-effectively implemented due to superimposed.
    Powerline Communication (PLC) is the transmission of data in power grids.
    These signals can be picked up by modern devices and be mis-interpreted as internal control signals. This can lead to malfunctions in the devices.
