Function/
LCD Display Default Options Description
Utility Quality
Normal
Low (97V~144V) Normal (100V~139V)
Select the voltage quality of
the input utility power. If Good
is selected, the UPS will go to
the battery mode more often
to supply the cleanest power
to connected devices. If Poor is
selected, the UPS will tolerate
more power fluctuations and go
to battery mode less often.
High (103V~135V) Escape to Function Menu
(Customized)
“Customized” shows up when
Maximum/Minimum output
voltage has been adjusted in
Advanced Setup Menu.
Function/
LCD Display Default Options Description
High Transfer Voltage
* = fine tune the MAX
O/P voltage
139V
135V ~ 144V
Escape to Function Menu
In Utility Quality settings, only
3 types of fixed voltage ranges
can be chosen. However, you
can fine tune the MAX O/P
voltage in this function.
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 the UPS from going to
Battery Mode as often.
Low Transfer Voltage
* = fine tune the MIN
O/P voltage
100V
97V ~ 103V
Escape to Function Menu
In Utility Quality settings, only 3
types of voltage ranges can be
chosen. However, you can fine
tune the MIN O/P voltage in this
function.
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 the UPS from going to
AVR Mode or Battery Mode as
often.
Sensitivity
Normal
Low Normal
If the connected equipment
can tolerate more power events
(Example: unstable power
often associated with stormy
weather), select Low Sensitivity.
The UPS will go to Battery Mode
less often. If the connected
equipment is more sensitive
to power events, select High
Sensitivity. The UPS will go to
Battery Mode more often.
