Three Phase Filters
F.LL.D3 series – SN/SH type
Residential / Light industrial environments
High performance slim design
This range of three phase filters offer a state-of-the-art solution for the
suppression of inverters and power drive systems. The multistage circuitry
helps to maintain very high performance across a broad frequency range.
In most installations, motor cable lengths of up to 20m can be achieved
without additional output filtering. Available in 480Vac or 520Vac versions
with terminal block connections on all models or optional threaded
terminals on the 16 Amp to 100 Amp variants inclusive.
