Schurter Inc., a manufacturer of circuit protection, connectors, switches and EMC products for the electronic and electrical industries, has added the FMCC SOL three-phase high-current filters to its filter line-up.
According to the company, the new compact, lightweight filters are designed to handle currents from 150 to 2,500 A at an ambient temperature 50 °C. With a voltage rating of 520V or 760V, the new filters are ideal for modern high-performance systems, including inverters for photovoltaic and wind power systems.
“The amount of renewable energy is constantly growing,” Schurter explains. “As a result, ever more powerful and physically larger systems are being built. [These] systems need high-performance inverters that are designed for optimal energy efficiency. Modern inverters with maximum power point (MPP) trackers generate interference in both directions—on the AC grid side and the DC panel side.”
To mitigate this interference, Schurter says, a filter from the company’s existing FMER SOL DC line 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.”
Standard connections for the FMCC SOL filter are made with screw connections or copper bars, but other connection types are also available. Modifications to the housing for custom fit are also possible. The FMCC SOL is UL-approved with VDE-approval pending.
