Schurter FMER SOL DC filter portfolio

Click2Contact

Schurter has announced an extension of its FMER SOL DC filter portfolio with a series for applications using three-phase AC.

The series is designed for rated currents from 150 to 2500 A which are suitable for increasingly powerful inverters that require filters on both the AC and DC sides. With UL approved voltage of 520 or 760 VAC, they can be used in high-performance systems such as inverters for photovoltaic, wind power systems as well as in industrial applications and quick-charge stations for electric vehicles.

Modern inverters with maximum power point tracking (MPPT) 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 nicely on the AC side with the FMCC SOL high-current series for three-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. The high voltage rating of 760 VAC allows their use in IT power grids.

The FMCC 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.
