The successful AC and DC filter series with currents up to 2500 A have big housings and heavy weights. The product weight was significantly reduced with an optimized potting compound. In the FMER SOL series, filters with a rated current higher than 250 A are able to benefit from this weight reduction, while in the FMCC SOL series all variants do.
The FMER SOL filters are designed for rated currents from 25 A to 2300 A at 55°C ambient temperature, and voltages up to 1200 VDC. The filter series is suited for use on the DC side of the inverter in photovoltaic and other DC systems.
The very high performance FMCC SOL 3-phase high current filters are designed to handle currents from 150 to 2500 A at an ambient temperature of 50 °C. With a voltage rating of 520 VAC or 760 VAC, they can be used in all high performance systems such as inverters for photovoltaic and wind power systems. Despite their high performance, they feature a compact, lightweight design.
