2. INTRODUCTION
2-1 Theory of operation
The main topology of the UPS consists of bypass path, AC-DC converter,
DC-AC inverter, battery charger, DC-DC converter, control circuit and
detection circuit. Moreover, the intelligent power management software is
also optional. The function and efficiency are superior to the traditional UPS.

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 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】.

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. 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 for the load. There is no power failure to
loading equipment.
2-2 Feature
The UPS, available in 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.
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.
Complete Protection
On-line double conversion design, pure sine wave 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 that travel along communication lines, therefore
providing you a complete “back door” protection.
Intelligent design
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 280V for 220V Series.
【
In addition, the UPS can accept large voltage variation of 80V to 280V. Wide
4
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.
Green function design
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.
User friendly interface
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.
Network Management
Build-in communication interface port supporting RS232 protocols enhances
the reliability and manageability of the UPS over all major operating systems,
including Windows 95/98, Windows NT, Netware, Unix, and others.
2-3 Annotation and symbol
The two signs shown on the manual indicating important instruction need to
be followed.
Read before Operation Maybe Dangerous/Follow Instructions
PROTECTIVE GROUNDING TERMINAL: A terminal which must be connected to earth ground prior to making any other connection to the equipment.
This symbol indicates the word “phase”.
This symbol indicates the principal on/off switch is in the “ON” position.
This symbol indicates the principal on/off switch is in the “STANDBY” position.
