Schaffner, a specialist in electromagnetic compatibility, has unveiled the FN 2200 range of EMC/EMI filters for use with photovoltaic (PV) solar-energy inverters.

The use of efficient EMC/EMI filters on the DC output side of PV inverters contributes to compliance with the EMC directive and increases system reliability.

When used in conjunction with appropriately sized EMC/EMI filters on the mains side, the FN 2200 DC filters help to meet the limits of EN 61000 and other binding EMC standards.

Such standards are frequently required for PV installations in Europe and other regions.

They also help to increase the service life of the solar panel, improve its reliability and reduce potential interference radiations away from the panel by keeping inverter-born high-frequency and leakage currents away.

The FN 2200 filters require up to 30 per cent less installation space compared to traditional solutions.

They also ensure minimum power loss of less than 0.0008 per cent related to the rating of the inverter.

The filters are available with ratings from 25A to 1,500A at 55C and for voltages up to 1,200VDC.

Filters without capacitors to ground (FN 2200B) are available upon request.

All models are UL, CSA and ENEC approved and are RoHS compliant.

The FN 2200 series is available direct from Schaffner and a number of specialist distribution sources.
