New Roxburgh high performance 1-phase and 3-phase EMI filters are drive-rated for AC drives and inverters. Single-phase EMI filters are also available for general purpose applications. Drive-rated 3-phase power line EMI / RF filters (starting at $77.00) are specifically designed for 230/460 VAC motor drives, inverters, machine tools and other 3-phase devices. Starting at $41.00, 1-Phase drive-rated EMI / RF line filters are designed for single-phase 120/240V AC and DC drives in noisy applications where increased filter performance is required. Roxburgh general purpose power entry modules are through-hole enclosure mounted line filters for 120/240 VAC devices. Starting at $5.50, the modules are also available with fusing and power switch options. Toroid ferrite cores, starting at $12.00, are a low cost way to reduce common mode noise in 1- and 3-phase applications.
