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.
