Description
Overview
The TekBox TBL5032-3 is a three-phase Line Impedance Stabilization Network (LISN) designed to measure line-conducted interference in the 9 kHz to 30 MHz frequency range, in accordance with CISPR 16-1-2 standard. It is designed for testing three-phase and single-phase AC-powered equipment with supply voltages up to 450 V / 260 V and current capacity of 32 A per phase and neutral. The device provides separate RF outputs for each phase and neutral conductor, enabling accurate measurement of conducted emissions. This US version includes an external 9 kHz coaxial high-pass filter instead of an integrated filter.
