R911268547
Bosch Rexroth Indramat's R911268547 (NFD02.1-480-030) is a mains filter used with frequency converters in motor drives. This filter serves to decrease cable borne radio frequency interference, making it suitable for industrial applications, power supply units, and wind power installations. Common appliance usage includes washing machines, where it prevents the electric motor's interference from affecting other devices via the power supply. The filter is designed for internal control cabinet installation, carries a current rating of 30A, and demonstrates effective attenuation between a frequency range of 150kHz to 30MHz.
The R911268547 (NFD02.1-480-030) filter, measuring 335mm (+/-1mm) in length, is compatible with the DKC drive controller power connection and successfully suppresses interference on the 24VDC NTM power supply. At 45°C, it displays a power dissipation of 8.7W. Its role is to prevent high frequency signals generated within a device from reaching the input power line and is typically connected between the rectifier input stage of the relevant switching power supply and the AC mains. This filter also blocks radio frequency interference or electromagnetic interference, completely or to a significant extent, which aids in preventing equipment malfunction. The filter works within a frequency of 50Hz to 60Hz, is suitable for vertical installation, and comes with one-year backup support.
