DC Line Impedance Stabilization Network V-Y-Δ TBLDC32-2
The TBLDC32-2 is a line impedance stabilization network that complies with CISPR 16-1-2 and CISPR 11 standards, designed to measure conducted emissions on DC lines in the frequency range of 9 kHz to 30 MHz. This device is intended for testing disturbance voltages at DC power ports, such as semiconductor power converters, with a maximum DC power supply voltage of 1000V and 32A. Conducted emissions can be measured on both forward and reverse power lines. Additionally, the rotary switch on the front panel allows for the measurement of common mode and differential mode emissions. The TBLDC32-2 is equipped with a toroidal inductor and features a robust stainless steel base with a flange for grounding connections.
