Tekbox TBLDC32-2 V-Y-Δ DC LISN
The TBLDC32-2 is a Line Impedance Stabilisation Network (LISN) designed for measuring conducted emissions on DC lines within the frequency range of 9 kHz to 30 MHz, in compliance with the CISPR 16-1-2 and CISPR 11 standards. This device is intended for testing disturbance voltages at DC power ports of semiconductor power converters and similar equipment, supporting DC supply voltages up to 1000V and currents up to 32A. It allows for the measurement of conducted emissions on both the forward and return supply lines. Additionally, the rotary switch on the front panel facilitates the measurement of common mode and differential mode emissions. The TBLDC32-2 features air core inductors and is housed in an enclosure with a robust stainless steel base, complete with flanges for secure ground connection.
