TBL5016 50 µH, 3-phase and single CISPR 16 Line Impedance Stabilization Network

The TBL5016-3 is a Line Impedance Stabilization Network for the measurement of line-conducted interference within the range of 9 kHz to 30MHz, according to the CISPR 16-1-2 standard. The device is designed for testing 3-phase and single-phase, AC-powered equipment with supply voltages up to a maximum 450V/260V and 16A. Conducted noise can be measured on each phase and on the neutral conductor. The TBL5016-3 has separate RF outputs for each phase and neutral and consequently can be coupled with the TBLM1 to split the emissions in its common mode and differential mode components. The single-phase DUT socket is available in country-specific variants.
