2System Description

On-line UPS connected between mains and load protects the load against voltage fluctuations, ripples, and

electricity cuts off.

Our UPS during the on-line operation provides stable pure sine wave. This pure sine wave is not affected

from the input voltage fluctuations. This helps to extend the life time of your sensible loads. Power factor

of the current consumed from the mains is nearly one. You do not have any problem on generator or

isolation transformer applications. Your reactive energy consumption decreases.

Over 80V mains voltage, smart battery charger charges the batteries. Batteries do not need any

maintenance.

In case of longer overload or inverter failure situation, UPS transfers the load to by-pass line, and load is

supplied from the by-pass input. When the normal conditions come back, UPS shall continue to supply

the load through inverter.

UPS control and management is done by digital signal processor ( DSP ) which is 200 times faster than

standard microprocessors. This helps to make your UPS smarter. DSP uses all the sources on optimum

conditions, observes the failure conditions, and communicates with your computer system.

UPS has standard communication interface. Using Inform software, you may protect your data and

operating Systems.

UPS block diagram is shown below.

Input and Output EMI filters

These filters prevent electromagnetic

interference between UPS, mains and loads.

Your UPS and loads are protected against high

voltage.

Input Thyristors

This helps to cut the energy flow between the

UPS input and boost rectifiers during the battery

mode or battery test.

Boost Rectifier

On mains operation, the boost rectifier adjusts

the mains voltage to the necessary DC voltage

level required for the inverter and helps to

provide sinus current with a power factor near

to 1 from the mains.

On battery mode it increases the battery voltage

level, required for the inverter and uses current

from the battery with a low ripple ratio thus

extending the battery life.

Inverter

The inverter helps to obtain a very constant AC

voltage level at the output by using DC voltage

at the boost rectifier’s output.

Inverter Thyristors

This helps to separate inverter from the output

electronically in case of by pass mode operation

or UPS output off conditions.

By-pass Thyristors

This helps to separate by-pass input from the

UPS output electronically.

Battery Thyristors

This helps to separate battery from the boost

rectifier electronically.

Battery

The necassary energy supply is obtained from

the batteries whenever the input mains supply is

not sufficient for the supply of the loads.

By-pass Switch

It is a mechanical switch which connects the ups

output to the bypass input and provides

uninterruptible transfer. It is generally used to

isolate the ups without disconnecting the load

from output and the mains from input.

By-pass Input

In some cases, it is requested to supply by pass

line from another mains or sources. In this

application, it is used split by-pass. (Please

inform your contact about your need)

Your UPS features:

Feature

Benefit

IGBT Technology

Transformerless design Compact design, small dimensions and low weight

DSP (digital signal processor)

technology

DSP is 200 times faster than standard microprocessors. This provides;

To use all the sources in optimum level

To observe carefully the failure conditions

PFC technology

High input power factor. This helps;

To consume low reactive power

Not to load the installation extra (cables, transformers, generators)

Clean power for the mains

Wide input voltage tolerance

(on-line operation even the mains is

between 80 – 280 V)

This helps to reduce battery usage and guarantee battery to be fully

charged and extend the battery life time.

On-line double conversion

technology

UPS output voltage is sine wave same as ideal mains source. UPS output

total harmonic distortion is very low.

Feature

Benefit

On-line and battery modes

operation against inrush current

Some loads when they are switched on, consumes high inrush current.

On such cases normal UPS switches off, or passes to by pass.

Our UPS behaves like a current source. (In case of high inrush current

consumption, UPS adjust the output voltage and fix the current value.)

Load is not affected the from inrush current.

On-line and battery modes

operations in short circuit

conditions

In case of a short circuit at output, UPS behaves like current source, (In

case of high current consumption, UPS adjust the output voltage and fix

the current value), and trigger the fuse between UPS and load. So short

circuit condition is over, and other loads are not affected.

Normal UPSs switch off in such cases.

Info (smart) Battery Management

Thanks to algorithms used in battery charging, battery lifetime is

extended. This helps:

To continue charging the battery even the mains input go down to

80V.

Load independent charging voltage.

Temperature controlled battery charging

Additionally;

Battery autonomy time is calculated, thanks to artificial intelligent

algorithms.

Current ripple is minimum level during the discharge.

Battery testing is available.

Temperature Management

UPS measures the temperature of different internal parts, and

calculates semi-conductor junctions’ temperature. This helps;

To calculate overloading time in a reliable way.

To protect against over temperature.

Overload Time Management

UPS continues its online operation for a certain period during overload

condition. This depends on overload percentage, and temperature of

semi conductors. Calculation is done as follows;

Load is supplied for a certain period by UPS, considering output

fuse temperature characteristics, and if by-pass input voltage is

available, and then pass to by-pass.

Meanwhile, if junction temperature passes the critical level, if by-

pass input voltage is available, then passes to by pass.

Non-moving parts except the fans

Maintenance free lead acid battery

usage

Less maintenance need

Communication interface Using Inform software, you can protect your data and operating

Systems.

Output voltage is not affected by changes on the mains input and load level.
