TekBox TBL5063-3 50µH 3-Phase Line Impedance Stabilization Network (LISN) 63A

Description

TekBox TBL5063-3 is a 3-phase Line Impedance Stabilization Network (LISN) designed for measuring conducted emissions in the 9 kHz to 30 MHz frequency range, compliant with the CISPR 16-1-2 standard. It is suitable for testing AC-powered 3-phase equipment with supply voltages up to 690V (line-to-line) / 400V (line-to-ground) and currents up to 63A.

The device features separate RF outputs for each phase and neutral, allowing it to be coupled with the TekBox LISN Mate to split emissions into common mode and differential mode components. It comes with an external 9 kHz high-pass filter to protect the RF input of measurement instruments.
