Tekbox TBLDC32-2 V-Y-Δ DC-LINE IMPEDANCE STABILIZATION NETWORK
The TBLDC32-2 is a Line Impedance Stabilization Network for the measurement of conducted emissions on DC lines within the range of 9 kHz to 30MHz, according to the CISPR 16-1-2 and CISPR 11 standard. The device is designed for testing disturbance voltages at DC power ports of semiconductor power converters and similar equipment with DC supply voltages up to maximum 1000V and 32A. Conducted emissions can be measured on the forward and return supply line. Furthermore, the rotary switch at the front panel enables measurement of common mode and differential mode emissions . The TBLDC32-2 is equipped with air core inductors. The enclosure has a robust stainless steel base with flanges for ground connection.
