The product can work with monitor software to detect battery at fix time, if there
is any fault such as battery cable open circuit or battery failure, the UPS can
detect the faulty information through communication ports to inform user.
Meanwhile, the UPS has self-protection function to shut down the charging
system and will turn to bypass mode (for the UPS with bypass model), when the
mains is normal, then it is power supplied by bypass, the LCD will display
"PWR DN", as well as the icon " " or the word "full".

3.10 Intelligent communication ports (with intelligent computer
monitoring function): (option)
When UPS is in inverter mode, the alarm will disappear after 40 seconds, and
at the same time it will automatically detect the load capacity, if the load is
less than 5%, UPS will consider as no load and will automatically shut off after
1 minute to ensure the battery full and prolong the battery life.
3.7 Automatically shut off when there is no load in inverter mode
(option):
The mains' frequency is 50HZ or 60HZ, when the UPS is connected with the
mains, it can automatically detect the mains' frequency, and the UPS output
frequency will keep the same as the mains' frequency (50HZ or 60HZ) before
even the main power failed.
3.8 Automatically distinguish output frequency:
3.9 Battery detection:
This series UPS can be monitored by PC through RS232、USB or SNMP card,
it can provide UPS on /off control and auto file-saving function for different
kinds of systems, such asWINDOWS98/NT/2000/ ME/2003/XP/Vistar
1.This series UPS can automatically detect the condition of the mains failed
and battery in low voltage; as well as UPS other working data ( LCD UPS)
2.When the mains is failed, the system will make countdown to automatically
save files, shut down system and UPS.
3.It can set system power supply time, make history record of UPS working
status, the mains status and so on.
When the system is in shut-down countdown, it can set UPS self-detection and
time for UPS on and off.

● Overload on main power condition: on main power condition, UPS will alarm for
60s if the load is over 110%, then it will turn to bypass mode, with ringing
disappeared either. Normal condition will recover if load has been decreased
to a normal range.
● Overload on normal inverting condition: on inverting power condition, UPS will
alarm with long ringing if load is over 110% .it will supply power again if load was
decreased to a normal range within 60 seconds and stop ringing at the same
time. Otherwise it will be shut down itself. Users need to turn on it manually by
pressing the ON button in the front panel or wait for the recovering of main power.
● Overload on abnormal inverting condition: on inverting power supply condition,
UPS will alarm with long ringing when load is over 125%, ups will automatically
shut down after 5s, end-users need to turn on it manually by pressing the ON
button in the front panel or wait for the recovering of main power.
● Short-circuit protection on inverting power condition, if the output of the ups
meets transient crest current and short-circuit strike, it will be limited in some
degree, if over 10ms, system will shut-down automatically. Users should turn on
manually (press the ON button in the front panel) or wait for the mains recovered.
(If on main power supply condition, the input fuse will get broken as the first
protection, and then ups will turn to inverting mode.)
3.4 Protective functions of online UPS:
On main power condition, system tracks the main power phase position
automatically, which can ensure the wave form of inverting output voltage
going simultaneously with the main power's. It can lower the spike pulse and
surge voltage occurring at the transfer between AC and batteries, so as to
ensure the disturbance and damage to equipment in the lowest level.
3.5 Phase lock function:
The intuitive LED and LCD display makes users can easily learn the
information of battery capacity, load capacity as well as the whole system
working status.
