FMCC SOL: 3-phase high-current filter

SCHURTER is expanding its successful FMER SOL DC filter with a series for applications using 3-phase AC. The new FMCC SOL high-performance filter series is designed for rated currents from 150 to 2500 A. The devices are ideal for increasingly powerful inverters that require filters on both the AC and DC sides. Large inverters find use in photovoltaics, wind energy systems as well as in industrial applications and quick-charge stations for electric vehicles.

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 V or 760 V, they can be used in all high-performance systems such as inverters for photovoltaic and wind power systems. Despite this high performance, they feature a compact, lightweight design.

The amount of renewable energy is constantly growing. As a result, ever more powerful and physically larger systems are being built such as for photovoltaics and harvesting wind energy. All these systems need high-performance inverters that are designed for optimal energy efficiency. Modern inverters with MPP (maximum power point) trackers generate interference in both directions: on the AC grid side and the DC panel side. On the DC side, a filter in the FMER SOL series can be used for currents from 25 to 2300 A. These are enhanced very nicely on the AC side with the new FMCC SOL high-current series for 3-phase AC from 150 to 2500 A. Filtering on both sides of the connection lines helps to meet common EMC standards.

The FMCC SOL filter family has UL approvals for ambient temperatures of +50 °C as well as +40 °C with higher rated current. They are approved for voltage ratings of 520 VAC and 760 VAC. The high voltage rating of 760 VAC allows their use in IT power grids.

The FMC SOL up to 250 A is equipped standard with M10 screw connections and starting at 320 A with copper bars. Other connection types (stranded wire or copper bars for current levels less than 320 A) are available on request. In addition, customer modifications to the switching or the housing are also possible on request.

For optimal matching to the inverter, SCHURTER offers its own EMC measurement service. In this way, the most efficient filter solution for a system can be easily determined.
