1. SUMMARY
1.1. INTRODUCTION
UPS(uninterruptible power supply) is a kind of power supply equipment that provides uninterruptible, high
quality and efficient and reliable AC power to the loads, it also has functions of protection and monitoring.
The UPS plays a very important role in power supply of computer and its network, communication, finance,
electricity, transportation, national defense, college, scientific research institutes and so on.
This 1KVA product is designed as advanced ON-LINE UPS that provide the multiple functions and good per-
formance.
1.2. FUNCTIONS AND CHARACTERISTICS
1. Advanced IGBT modules are used in our UPS. The electronic components we used can work normally for
more than 300,000 hours.
2. Digital control technology with high efficiency and the most reliable controller algorithm design are used
to optimize the output parameters of the machine.
3. Self-diagnose before start. It can find potential problems of the UPS in time to avoid any losses.
4. Double conversion on-line topology which makes the output of the UPS a pure sine wave electricity with
constant frequency and voltage, low noise and no interruption of the main power fluctuation. It provides
more comprehensive and perfect protection for the users’ equipments.
5. No transfer time for the output of the UPS when the main power fails or restores. It meets the high stan-
dard and high request of the precise instruments.
6. The bypass function. When UPS meets a fault, it can transfer to bypass with no interruption to supply
power to loads and provide alarm.
7. Advanced voltage compensation technology. It makes the input voltage range from 115v to 295v which
reduces the battery usage and enhances the adaptive ability against the bad main power variation.
8. The AC input frequency is 50Hz/60Hz. Advanced wide frequency input technology makes the input fre-
quency range wider. When the output frequency is 50Hz, the range of the AC input frequency is 45Hz-
55Hz, When the output frequency is 60Hz, the range of the AC input frequency is 55Hz-65Hz.The UPS has
a good compatibility with generator. It is suitable for different types of single-phase generators.
9. The advanced PFC( power factor correction)technology on the input of the UPS makes the input power
factor more than 0.98. It increases the power efficiency, removes the harmonic noise from UPS to utility,
lowers the UPS operational cost. It’s really an economic environmental protection power supply.
10. Intelligent function without surveillance. When main power is on blackout, the UPS will start battery
mode to supply power to loads.
When battery voltage is low, UPS will protect itself and shut down automatically. When main power
restores, UPS will detect main power to determine whether the voltage and frequency are normal. If
normal, UPS will turn on automatically to supply power to loads; if abnormal, UPS will start charger to
charge the battery. The UPS will not turn on to supply power to loads until the voltage and frequency
of the main power restore normally.
11. Cold start function. When there is no main power, UPS can be started by battery pack. It can meet the us-
ers’ emergency needs. The cold start function is quite strong. UPS can be cold started under the full load
situation.

12. UPS protection function:
When the main power input/output voltage is too high or too low, overload, short-circuit, inverter
temperature is too high, low voltage and overcharge of battery, network surge and so on, UPS has a
protection function.
13. 13.Rack-Tower conversion LCD design. No matter what angel to watch the display, only press the key
slightly can meet your perspective needs. The content displayed on the interface is rich. The capacity of
the loads and the battery can be saw directly and the FLASH pictures and fan rotating icon can be dis-
played when charging. So it is easy to know it’s operation. When UPS fails, it can show the fault code, the
machine can be maintained as soon as possible by inquiring fault code table.
14. 14.The UPS can communicate with the computer with intelligent UPS monitoring software through the
RS232 interface. All the parameters clearly display on the communication interface. Computer can control
multiple functions of the UPS directly.
15. 15.Via internal or external SNMP adapter, UPS can go on internet and provide the latest information and
power messages. You can monitor and manage the UPS status through all kinds of network management
system.
16. 16.Convenient USB communication. You can see the operation of the machine completely. Even if the
RS232 interface is occupied or connected at the same time, it will automatically switch to USB connection.
17. 17.ECO function can help you save electricity. When the input mains power is in a fixed range, the loads
is supplied with power by mains power directly, the inverter is on waiting; when input mains power is
abnormal, it transfers to inverter to supply power to loads at once.
18. 18.In order to ensure the power of the important loads can last for a long time, you can plug the impor-
tant loads into the second power down socket. When the battery voltage is below the predetermined
value, only the first cut-off power socket is broken off, the second power down can keep on supplying
power until the battery voltage reaches protect point and shut down.
19. 19.Adopt international standard rack-mounted size. Whether you want to put it on the office desk or in the
rack-mount as a system to manage, It can present your personal style with corresponding components.

tenance, please abide the local safety instructions and relative laws, otherwise, it will result in personal injury
or equipment damage. Safety instructions in this manual act as a supplementary for the local safety instruc-
tions.
Our company will not assume the liability that caused by disobey of safety instructions. Please note the fol-
lowing:
1. Don’t use the UPS when the actual load exceeds the rated load.
2. There are high-capacity batteries in the standard type UPS. You mustn’t open the enclo-
sure or it will lead to electric shock. If it needs internal maintenance or battery replace-
ment, please send it to the designated site.
3. Internal short-circuit of the UPS will cause electric shock or fire. So don’t place the contain-
ers equipped with liquid on the top of the UPS so as not to cause danger of electric shock
