The PVDC 8301-400 was especially designed to measure all kinds of disturbance voltages at the DC-side of photovoltaic inverters. These are in particular the disturbance voltage between one conductor and reference ground (unsymmetrical disturbance voltage), the common mode disturb-ance volage of a pair of conductors against ground (asymmetrical disturbance voltage) and finally, the differential mode voltage between two conductors.
The symmetric DC-LISN PVDC 8301 400 can be used for measuring the disturbance voltage in the frequency range from 0.15 MHz to 30 MHz at the input of photovoltaic inverters.
The permitted continuous current is 400 A with activated fans and 200 A without fans. The PVDC 8301 400 is able to handle 500 A for a short period of time.
