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 battery source (battery). 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 UPS inside.

WARNING !

☆Be sure to operate the UPS within the rated power of the UPS.

☆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,

nve

rte

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 supply to the

inverter and charge the battery to its full capacity all the time, ready to support the

output load in case of AC source failure.

Perhaps one may doubt if it is worthwhile to buy a UPS. But when you use a

calculator to add up the

dire

ct and indirect loss caused by AC failure, you will

immediately find that the money you save in 2 or 3 times of AC failure can already

compensate the cost of a UPS. Besides, the life expectancy of a UPS is at least 5 to

8 years, you may already get back the expense on the UPS within one year.

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 requires advanced technology, intelligence,

experience and the most important, be c

ons

iderate

the user. Therefore we spend

years and huge investment in developing the most rugged, intelligent and reliable

UPS for the market, safe and convenient UPS for the user.

1-2

Besides, the knowledge of choosing the best and most suitable UPS can be easy or

can be difficult, it depends on whether you know the key points or not. The most

obvious specification is the power, it depends on how lar

e is your load. Usually, an

allowance of 50% more power must be added to the current power you needed, both

for tolerance and future expansion. Of course you can add more than 50% if you

expect a larger increase of load in the future.

Another important point is the reliability, the prime aim of a UPS is to protect your

load, and therefore the UPS should be much more reliable than the AC source.

Those unfortunate UPS users who bought a unreliable

UPS

suffer the

problem of frequent break down of the UPS, even more frequent than AC failure,

the cost of repairing is more the cost of the unit itself.

The last point is to choose an honest and experienced suppler who can help you

to choose the correct UPS, react promptly in case of UPS problem. Then, you can

save your money as well as buy a correct, suitable, and reliable UPS that is the

same as buy insurance to your load.

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. They are explained as below.

Normal Operation Mode:

The rectifier converts the AC input to DC power to supply the inverter and charge the

battery simultaneously. All the fluctuations, surges and spikes of the AC input is

removed during AC to DC conversion, therefore the AC supplied by the inverter is

clean and stable.

1-3

Back-up Mode:

Since the battery is connected directly to the DC bus, when the AC failure, the

battery change immediately

from

receiver to donor, supply energy to the inverter

instead of receiving energy from the rectifier. The

output

is not interrupted.

Therefore, the load connected to the output is protected.

Reserve Mode:

When the inverter is in abnormal conditions, such as over temperature, short circuit,

abnormal output voltage or overloaded for a period exceed the inverter’s limit, the

inverter will automatically shutdown, 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.

1-4

Maintenance Bypass Mode:

In case of UPS maintenance or battery replacement, and 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

interrupted during

manual bypass transfer procedure. Therefore maintenance bypass switch keeps

continuously power supply to the load. Electricity will not exist in UPS except the

output transformer, thus ensure 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 is fail, under overload condition,

or during maintenance.

The normal operation with battery connected can provide a clean, stable, free from

any spikes and surges, regulated and uninterruptible power to the load. Therefore,

the UPS and be regarded as a perfect AC

power

source

except the back-up time

under mains failure is limited by the capacity of battery connected.

1.2. Features and Advantages

(a) Reliable input protection: Circuit breakers is put in each individual input

loop to ensure power can continue through the other loop in case of breaker trip

caused abnormal condition in either rectifier or load.

(b) Input surge protection: MOV (surge protector) is added at the input, provide

sufficient protection to both UPS and the load from any lightning or surge

caused by neighboring large loads.

therefore, very low

noise

is emitted and never interfere other equipment

connected to the same AC source.

(d) Ruggedness: The rectifier employ phase control technology to regulate the

DC bus voltage, so it can charge the battery directly, it is the most efficient

method to charge the battery. Besides, the component used is SCR, the

component get merits by its ruggedness under poor condition. Also, big 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 method

conv

ert the DC power to AC power. Therefore, number

of components is fewer, in return, reliability is improved, size and weight of

UPS is reduced, then the transportation cost is cheaper, performance improved

and the acoustic noise is eliminated too.

(f) True Galvanic isolation: An isolated transformer is put at the output, can

solve the problem of

poor

input

grounding and can accept 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. Besides, the user gets the bonus of

attenuation of common mode noise from the output isolation transformer.

1-6

(g) P&P Modular design: The power circuit is separated into several modules

plugged into slots in

UPS,

which is easy to pull out, permit quick

maintenance and easier trouble shooting. Therefore, it can be regarded as plug

and play modules.

(h) Cold start function: the UPS can be started without AC source, that is, can

be started with battery only, because current limit circuitry is added. It can

prevent the problem of many UPS that the big inrush current blow the battery

fuse and hurts the DC capacitors when battery is connected to empty DC bus

(before the DC bus is energized).

(i) Multi-CPU design: Several CPUs are employed in the control circuit, critical

functions are designed to parallel redundancy to improve reliability. Therefore,

in case of one CPU fails the other CPUs keep on their duty and the output AC

will not be affected.

(j) Defense to mis-operation: The UPS is designed with breaker on/off sensor,

power supply sensor etc. Therefore any operational mistake made by the user

causes no harm to the UPS.

(k) Wide input range: The UPS is designed to accept extra wide input range, so

that it can work comfortable under poor AC source. Also, all the input

components used are especially selected to handle extreme high voltage and

high current.

(l) Tolerate harsh environment: Each component of the UPS is chosen with

larger safe margin to accept extreme environment, such as temperature, humidity,

attitude, shock or contamination.

(m) Intelligent charger: The UPS will automatically recharge (boost charge) the

battery every time after the battery is consumed to a voltage 2V/Cell, so that the

battery can be recovered to the full capacity as soon as possible to be ready for

the next back-up. Besides, in order to keep the battery in the best condition, the

UPS will boost charge the battery for several hours (selectable) automatically

every month. To avoid over charging the battery, Boost charge will stop when

the ambient temperature is over 35 ℃(95℉).
