Description
Input adaptability mode 1: It is applicable to
normal power grids, normal DGs, and DGs that are
sensitive to the output reactive component. Input
adaptability mode 2: It is applicable to normal
power grids, normal DGs, and input power sources
with high internal resistance.
Description
If this parameter is set to Enable, the output
current is displayed as 0 with no load output,
and the output load rate is displayed as 3%.
When this parameter is set to Disable, the
output current and output load rate are not
adjusted to 0.
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 inverter mode,
which impacts the system. This parameter
limits the number of transfers between bypass
mode and inverter mode within 1 hour, which
ensures system security.
Monitors the current differences between
racks or modules. If this parameter is set to
Enable, the Mod. Cur. Eql. Data can be
viewed on the running information page.
Specifies whether an Inverter asynchronous
alarm can be displayed on the monitoring
page when the inverter does not track the
bypass input. Power supply is not affected no
matter whether this parameter is set to Enable
or Disable.
Specifies whether to automatically clear the
alarm and restart the power module when the
rectifier or inverter shuts down due to a bus
overvoltage alarm. If Bus overvoltage
