EMC-Filter CNW 173

DC filter for photovoltaik (2 lines)


The REO sensors use a Hall-effect device in their magnetic circuit to measure the primary current, which is electronically converted to a proportional output current.It measures frequencies up to 150 kHz. The current sensors are integrated into the filter and are ready for connection. There is no additional installation effort required. Attention! This option will change the mechanical dimensions of the filter!


  • protection of solar cells from high frequency
  • noise generated by the inverter
  • designed to conform to existing and planned
  • optional with current transformer
  • compact construction
  • low temperature rise
  • universal protection for all inverters
  • optional anti-surge protection

Typical applications

The DC-filter surpresses grid-bound troubles of inverters for renewable energies like solar and wind power.
