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 150A to 2,500A.
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 150A to 2,500A at an ambient temperature of 50°C. With a voltage rating of 520V or 760V, 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 25A to 2,300A. These are enhanced very nicely on the AC side with the new FMCC SOL high-current series for 3-phase AC from 150A to 2,500A. 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 520VAC and 760VAC. The high-voltage rating of 760VAC allows their use in IT power grids.
The FMC SOL up to 250A is equipped standard with M10 screw connections and starting at 320A with copper bars. Other connection types (stranded wire or copper bars for current levels less than 320A) 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.
