The S Series filters will protect equipment from malfunctions due to conducted interference coming into the equipment from the line, especially line-to-line noise and transients. In addition, they combine line-to-ground interference rejection filters with additional circuitry to reduce line-to-line transients. They are also effective in controlling emissions in equipment using SCR and T²L circuits, for compliance with FCC Part 15, Subpart J and VDE 0871, Level A, down 150 kHz. The S Series is an N=2 line-to-ground impedance common mode and an N=3 impedance for line-to-line differential mode interference. The suppression allows most equipment, including switchmode power supplies, to meet FCC specifications for conducted emissions. Additional max. line amps available as special order items. Maximum Leakage Current (Line-to-Ground): 0.4 mA @ 120 VAC, 60 Hz; 0.7 mA @ 250 VAC, 50 Hz. Hipot Rating (1 minute): Line-to-Ground — 2250 VDC; Line-to-Line — 1450 VDC. Operating Frequency: 50/60 Hz. Maximum Rated Voltage: 250 VAC.
