Description
The output voltage can be
slightly adjusted based on
the onsite power distribution
condition to ensure a
minimum difference between
the output voltage and the
bypass voltage and 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 Output freq.
track rate (Hz/s) is slow, the
inverter frequency is different
from the bypass frequency
when the bypass frequency
changes. If output is
overloaded or the inverter is
faulty, an interruption (less
than 20 ms) occurs when the
UPS transfers from normal
mode to bypass mode. If
Output freq. track rate
(Hz/s) is fast, the inverter
frequency is unstable.
If the mains is not
functioning normally, the
UPS will transfer to battery
mode. When batteries reach
the EOD threshold, the
bypass is disabled, and EOD
restart is Enable, the UPS
will restart as soon as the
mains resumes.
If EOD restart is disabled,
clear the alarm manually or
enable the restart function
for the UPS.
