Description
onsite power distribution
condition to ensure a minimum
difference between the output
voltage and the bypass voltage
and to facilitate uninterruptible
power supply when the UPS
transfers from normal mode to
bypass mode.
Specifies the system output
frequency level.
This parameter can be adjusted
based on site requirements. If the
rate is slow, the inverter
frequency is generally different
from the bypass frequency when
the bypass frequency changes. If
the output is overloaded or the
inverter is faulty, an interruption
(less than 20 ms) occurs when
the UPS transfers from inverter
mode to bypass mode. If the rate
is fast, the inverter frequency
may be unstable.
The UPS transfers to battery
mode when the mains is
abnormal. When batteries reach
the end of discharge (EOD)
threshold and the bypass is
unavailable, the UPS powers off.
After the mains recovers, the
UPS will automatically restart if
EOD restart is set to Enable.
If EOD restart is set to Disable,
manually rectify the fault and
restart the UPS or enable the
EOD restart function.
If EOD restart is set to Enable,
the UPS starts working after the
time set for EOD restart delay
when the input recovers from a
power failure upon battery EOD.
