DC Filter

DC Filters are EMI Filters for DC Applications

DC Filter

Most power supplies operate using DC voltages.  DC EMI Filters allow DC and low-frequency currents to pass through while blocking harmful high-frequency currents.  This allows for the device to work correctly by diverting unnecessary noise. 

This series carries CE and UL approvals and offers a current range from 5 to 3000A with nominal voltage up to 1000 Vdc.

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 features a compact case with screw and bus bar connectors.  Customized solutions are available to satisfy various application requirements.
