Description
Overview
The TekBox TBLDC32-2 is a Line Impedance Stabilization Network (LISN) specifically designed for measuring conducted emissions on DC power lines in the 9 kHz to 30 MHz frequency range, in accordance with CISPR 16-1-2 and CISPR 11 standards. It is designed for testing disturbance voltages at DC power ports of semiconductor power converters and similar equipment with DC supply voltages up to 1000 V and continuous current capacity of 32 A (25 A continuous, 32 A for 15 minutes). The device features a rotary switch for measurement of forward/return supply lines and separate common mode and differential mode measurements.
