Compact high current DC EMC/EMI filter

DC Filter FN2211HV and FN2210HV


Compact high current DC EMC/EMI filter

  • Reduces conducted emissions towards the solar panel
  • Reduces the probability of EMI radiation off the solar panel
  • Helps to prevent premature panel aging
  • Helps to meet international EMC regulations
  • Most compact standard solution in the industry
  • FN2210HV without Cy capacitors to ground

Features and Benefits

Installed between the PV inverter and the solar panel, the FN2211HV and FN2210HV DC filters are used to influence positively the conducted emissions on the panel side of the system. Therefore the DC filters significantly reduce the potential for highfrequency (HF) interference radiation of the panel. The filter also helps to prevent premature panel aging because of HF stray and leakage currents.

Typical Applications

Rated operating voltage

The FN2211HV/FN2210HV series are primarily designed for PV inverter applications between 250 and 2’300 A. However, they can potentially also be applied in other DC applications within published specifications, like UPS, DC motor drives, energy/battery storage systems, or DC charger installations.
