Description
If this parameter is set to Enable, the
BCB will trip in case of EOD.
Description
Input adaptability mode 1: It is
applicable to the normal power grid
and DGs, and DGs that are sensitive
to the output reactive component.
Input adaptability mode 2: It is
applicable to the normal power grid
and DGs, and input power sources
with high internal resistance.
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.
Cross currents occur during the
transfer between bypass mode
and normal mode, which impacts
the system. This parameter
specifies the number of transfers
between bypass mode and
normal mode within 1 hour,
which ensures system security.
