DC Filters

High Performance and High Voltage DC EMI Filters

DC Filter

DC EMI Filters allow DC and low-frequency currents to pass through while blocking harmful high-frequency currents.  This allows a device to work correctly by diverting unnecessary noise. 

Enerdoor DC Filters were designed specifically for the photovoltaic industry.  The FIN1220, FIN1520 and FIN7212 filters are installed between PV inverters and solar panels to reduce electromagnetic interference in the DC power line.

The FIN1220.0V, FIN1520.0V and FIN7212 filters offer the possibility of ground connection separated from the virtual zero point. This is particularly beneficial for critical networks on the protective earth conductor.

This series carries CE and UL approvals with a current range from 5 to 3000A, nominal voltage up to 1000 Vdc, and a compact case with screw and bus bar connectors.  Customized solutions are available to satisfy various application requirements.  

Benefits of DC Filters:

  • Protect solar panels
  • Reduce EMI interference
  • Excellent differential and common mode attenuation
  • Low leakage current
