Description
The value of Input
adaptability can be Strong
or Weak. Strong 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
Disabled, the output current
and output load rate are not
adjusted to zero.
If this parameter is set to
Enable, the current at no
load will be calibrated once
automatically. This function
can be used only when the
UPS carries no load.
Set this parameter based on
the output interruption time
acceptable to loads.
