N242X Series Low Earth Leakage High Performance RFI/EMI Power Filters

ETS-Lindgren's Model N242X Power Filters are low leakage RFI/EMI high-performance power filters, designed for use where low earth leakage is a requirement. 

 

 

ETS-Lindgren's Model N242X Power Filters are low leakage RFI/EMI high performance power filters, designed for use where low earth leakage is a requirement. The performance is maintained up to full load in both symmetric and asymmetric modes. The leakage current is directly proportional to the potential difference between the neutral and earth leads at the filter input terminals. Solid and permanent earthing of the case is essential for safety and to ensure optimum performance.

Key Product Information


​Maximum Protection

N242X filters have an extremely low current leakage. They are fully tested for attenuation performance, voltage withstanding to 1 kV for thirty seconds, and insulation resistance.

Insertion Loss

The N242X series of filters provide 100 dB insertion loss from 150 kHz to 40 GHz in both symmetric and asymmetric modes up to full load.

Mobile Installations

These filters are suitable for mobile installation applications.

End Chamber Accessibility

For termination of input and output cabling, these filters have fully accessible end chambers.

RoHS Compliant, CE Marked

N242X filters are RoHS compliant and are also CE marked for compliance with the low voltage directive.

Applications

  • Military Field Installations

  • Commercial Installations Using Motor Generator Sets

  • Filtering of Mains Supplies Where Maximum Safety is Required N242X Series Power Filters Series

  • Under certain circumstances, the N242X Filters may be used with Earth leakage safety cut-outs. Please contact ETS-Lindgren for further information.
