Normal This function determines how the
UPS will switch to AVR or Battery
Mode.
3 different output voltage ranges
can be chosen according to the
quality of the AC utility service in
your location.
If your utility service is not stable,
you can select Poor (97V~135V).
The UPS will go to AVR or Battery
Mode less often to tolerate the
utility power fluctuations.
If your utility service is stable, you
can select Good (103V~129V). The
unit will go to AVR or Battery Mode
more often.
MAX O/P Voltage
* = fine tune the
MAX O/P voltage
H129~H135
Escape to
Function
Menu
H132 In Utility Power settings, only 3
types of fixed voltage ranges can
be selected. However, you can fine
tune the MAX O/P voltage with this
option.
If the utility voltage is usually high
and the connected equipment can
work in this condition, you can set
the output voltage range higher to
reduce how often the UPS goes to
AVR Mode or Battery Mode.
MIN O/P Voltage
* = fine tune the MIN
O/P voltage
L97~L103
Escape to
Function
Menu
L100 In Utility Power settings, only 3
types of voltage ranges can be
selected. However, you can fine
tune the MIN O/P voltage with this
option.
If the utility voltage is usually low
and the connected equipment can
work in this condition, you can set
the output voltage range lower to
reduce how often the UPS goes to
AVR Mode or Battery Mode.
