Description
input adaptability applies to the
D.G. or input sources whose
input current has high frequency
oscillation. In this mode, the total
distortion of the input current
waveform (THDi) is poor, but
the system is stable. Weak input
adaptability is suitable for mains
and AC input sources.
Description
If this parameter is set to Enable,
the output current is displayed as
0 when no load is output. The
output load rate is displayed as
3%. When this parameter is set to
