CAUTION !
☆Hazardous voltage exits inside the UPS (includes the connection
terminals). Cable connection and maintenance should be done by
professional or qualified personnel.
☆ The UPS has its own internal power source (batteries). The output
terminals may be live even when the UPS is not connected to the AC
supply.
☆ DC capacitors are employed in this unit. Hazardous voltage still
exists even when the unit is not energized. Do not touch any part of
the inside of the UPS.
WARNING !
☆ Be sure to operate the UPS within the rated power level.
☆Prevent direct exposure to direct sunlight, rain or contaminating
environment.
☆ Only qualified technicians should replace the batteries. Since
batteries have high short-circuit current capacity, mistakes in
connection or disconnection can cause severe burns or death to
servicing personnel.

1. SYSTEM OVERVIEW
1.1. Construction of the UPS
General Topology：
The UPS system is composed of input breakers, input filter & protection network,
rectifier, battery bank, inverter, static switch, bypass breaker, isolation transformer
and output filter. The basic topology is shown in the diagram above. Under normal AC
mode, energy from the AC source is converted to DC power and supplied to the
inverter to charge the batteries to its full capacity all the time, ready to support the
output load in case of AC source failure.
Although the principle and operation of a UPS seems simple and straightforward, the
requirement for a reliable and intelligent UPS makes the design and manufacturing of
a high power UPS one requiring advanced technology, intelligence, experience and
most important, consideration of the user interface. Many years have been spent in
designing the most rugged, intelligent and reliable UPS for the market, and a safe and
convenient UPS for the user.
Choosing the best and most suitable UPS for a given application can be easy or
difficult, depending on the client’s knowledge of key parameters. The most obvious
specification, output power, depends on the size of the load. Often, an allowance of
50% more power is added to the present load requirement, both for tolerance and for
future expansion.

Another important issue is reliability. The prime aim of a UPS is to protect your
load. Therefore, the UPS should be much more reliable than the AC source. An
unreliable UPS may suffer the problem of frequent break down, even more frequent
than AC failure, and the cost of repair may become more than the cost of the unit
itself.
Generally, there are four different modes of operation, the NORMAL OPERATION
MODE, the BACK-UP (BATTERY) MODE, the RESERVE MODE and the
MAINTENANCE BYPASS MODE. These are explained below.
Normal Operation Mode:
The rectifier converts the AC input to DC power to supply the inverter and charge the
batteries simultaneously. All the fluctuations, surges and spikes of the AC input are
removed during AC to DC conversion. Therefore the AC supplied by the inverter is
clean and stable.
1-2

Back-up Mode:
Since the batteries are connected directly to the DC bus, when the AC fails, the
batteries change immediately from receiver to donor, supplying energy to the inverter
instead of receiving energy from the rectifier. The output AC is not interrupted.
Therefore, the load connected to the output is protected.
Reserve Mode:
When the inverter is in an abnormal condition, such as over temperature, short circuit,
abnormal output voltage or overloaded for a period exceeding the inverter’s limit, the
inverter will automatically shut down in order to protect itself from damage. If the
utility power is normal, the static switch shall transfer the load to the reserve source
without interruption of AC output.
1-3

Maintenance Bypass Mode:
In case of UPS maintenance or battery replacement, and where the load cannot be
interrupted, the user can turn off the inverter, close the bypass breaker and then open
the rectifier and reserve breakers. The AC output will not be interrupted during
manual bypass transfer procedure. Therefore, the maintenance bypass switch keeps
continuously supplying power to the load. Electricity will not exist in UPS except the
output transformer, thus ensuring the safety of service personnel.
Generally, the UPS is expected to run 24 Hours a day in normal operation mode once
it is installed, except when the utility power fails, under overload conditions, or
during maintenance.
Normal operation with batteries connected provides clean, stable, regulated and
uninterrupted power to the load, free from any spikes and surges. Therefore, the UPS
can be regarded as a perfect AC power source, limited in back-up time, under mains
failure, only by the capacity of the batteries.

1.2. Features and Advantages
(a) Reliable input protection: Circuit breakers are placed in each individual input
loop to ensure power can continue through another loop in case of breaker trip
caused by an abnormal condition in either rectifier or load.
(b) Input surge protection: An MOV (surge protector) is added at the input,
providing protection to both UPS and the load from any lightning surges, or surges
caused by neighboring large loads.
(c) EMI suppression: An EMI filter is added to meet the international EMC limits.
Therefore, very low noise is emitted, and no interference is supplied to other
equipment connected to the same AC source.
(d) Ruggedness: The rectifier employs phase control technology to regulate the DC
bus voltage. This is the most efficient method to charge the batteries. The SCR
used are inherently rugged. Additionally, a large inductor is added at the input to
avoid deforming the AC source waveform.
(e) High frequency design: The inverter uses high frequency, high efficiency IGBT,
PWM methodology to convert the DC power to AC power. Therefore, the number
of components is fewer, reliability is improved, and the size and weight of UPS is
reduced, performance is improved, and acoustic noise is minimized.
(f) True Galvanic isolation: An isolation transformer is placed at the output.
This can solve the problem of poor input grounding, can allow a different ground
between input and output, can avoid the annoying problem of ground leakage
current, and can be tied to any potential provided on site. The AC output is
isolated under every mode of operation. Additionally, the user gets the bonus of
attenuation of common mode noise from the output isolation transformer.
