Fig. 2.1 is the hardware block diagram of the UPS.
The UPS operation is described as below:
When the utility power is applied into the UPS, it was divided into two ways after going
DE
through the breaker and EMI filter. One way is connected to AC-DC converter which
converts the utility AC power into a DC voltage which is called DC-BUS voltage then
divide into two path. One path goes to charger which converts the DC-BUS voltage into a
proper DC voltage to charge the UPS battery. The other path goes into DC-AC half bridge
inverter. The other way works as a bypass path. The bypass relay near the output will
choose either the bypass path or inverter output. In general, the UPS will internally do the
self-diagnosis. If there is no problem, the bypass relay will choose the inverter output.
This is so called “ON-LINE mode”.
5
SHEET 6 TO 7
In case the utility power fail, the AC-DC converter and charger will be off duty. The
DC-DC converter works and converts the battery voltage into DC-BUS voltage. The
DC-AC inverter converts the DC-BUS voltage into AC voltage. This is so called
“ON-BATTERY mode”.
The auxiliary power circuit supplies the designated power to all the control circuits.
for the load. There is no power failure to loading equipment.
2-2 Feature
TE
R
Because the DC-AC inverter is always working, the DC-DC converter can work rapidly
and replace the AC-DC converter while the utility power fails. Furthermore, the bypass
relay continuously keeps in the position of inverter output to supply the regulated power
CE

The UPS, available in 700VA, 1KVA, 2KVA and 3KVA, is an advanced on-line UPS
providing reliable and consistent sine-wave quality power to vital equipment. It supports
personal computers, networks, servers, telecommunication equipment and a variety of
other facilities. With its outstanding protection features, the unit keeps your applications
safe and running smoothly at all times.
High power density
DO
C
Other than traditional UPS adopting 0.7 output power factor, the UPS uses the latest
technology and highest quality components giving output power factor up to 0.8.
Compared to other UPS (1000VA/700W), these UPS series boosts a 12% more output
power. This UPS with its compact size, generates higher power density thus giving
convenience to the users. Moreover, through the use of advanced technology, the UPS
efficiency increases to more than 87%. Compared with other traditional UPS with only 80
LT
A
to 85% efficiency, this UPS produces greater electric power efficiency at less electric
costs.
PFC (Power Factor Correction)
With this function, the investment in the capacity of circuit breakers can be reduced,
specially it will be highly regarded as an important feature in critical load applications.
DE
Complete Protection
On-line double conversion design, pure sinewave output and zero transfer time provide
best protection. With a built-in surge, spike and line noise protection, the UPS prevents
destructive hardware damage and extends system life. The EMI/RFI filtering design
prevents electrical noise from affecting computer operation and data files. Besides, the
UPS provides built-in Fax/Network cable (RJ11/RJ45) jacks protecting your hardware
from surge, spikes and line-noise which travel along communication lines, therefore
providing you a complete “back door” protection.

SHEET 7 TO 8
Intelligent design
TE
R
Integrated with a microprocessor, the UPS is able to perform intelligent functions. The
UPS triggers over-voltage protection function and transfers to “On- Battery mode” even
when utility voltage exceeds 300V for 200V-series. In addition, the UPS can accept large
voltage variation of 65V to 138V for 100V-series or 130V to 275V for 200V-series.
Wide input voltage range means less battery power usage frequency and longer battery
life-span. Besides, programmable outlet design, suitable for power management, is also
included in this unit.
Considerate design
CE
N
Battery start function allows startup of the UPS even when there is no AC line available.
In addition, the UPS which was shut down by remote control during power line blackout
will restart automatically when AC power recovers. Using our automatic frequency
sensing function to match input and output frequency, users don't need to set either 50Hz
or 60Hz. Other features, such as UPS self-diagnosis and flexible external battery pack,
are also included.
Green function design
User friendly interface
DO
C
The UPS comes with an intelligent fan design, which can have variable fan speed
depending on load status, thereby saving the use of power and reducing audible noise.
Besides, the operation in sleeping mode is designed to just keep charging which saves the
energy a lot.
LT
A
The UPS provides a variety of functions which meet users’ needs. Users can instantly
understand the status of the UPS via the informative LED display. Audible alarms, bar
meters and status indicators, such as battery replace indication, UPS fault, line condition,
overload etc. are simple and easy for user to understand. Moreover, users can simply reset
the circuit breaker instead of having to replace a fuse in the event of output overload.
Safety approvals
DE
The UPS has passed various safety regulations. UL/cUL, TUV/EMC, TUV/GS, CE mark
and other safety approvals, proves that the UPS is a safe reliable solution to your power
problems.
Network Management
Build-in communication interface port supporting RS232 and Dry contact protocols
enhances the reliability and manageability of the UPS over all major operating systems,
including Windows 95/98, Windows NT, Netware, Unix, and others. Besides, the UPS
also supports the Simple Network Management Protocol and Hyper Text Transfer
Protocol via plugging a SNMP/HTTP adapter into the build-in SNMP slot.

the case or front panel is very dirty, use a neutral, non-abrasive detergent. Do
not use alcohol or ammonia based solutions.
zWhen moving your UPS, always handle it with care.
zAvoid spilling liquid on the UPS.
zThe equipment should be repaired and installed by individuals with previous
training.
When installing this equipment, it should be noted that the leakage current of the UPS and
its loads must not exceed 3.5mA in total for safety.
