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.

Description of block diagram

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

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.

6. Overload: The LED indicates UPS’ load exceed the rating, after a

limited period, the UPS will transfer to “BYPASS mode” and the LED

will still light on to alarm the user.

7. Load: “Level LEDs” shows the UPS load level when the LED lights up.

8. Battery: “Level LEDs” shows the current battery capacity when the LED

lights up.

9. Battery low: The LED indicates the battery in battery low condition.

10. Battery replace: The LED indicates the batteries are weak and suggest

the user to replace the batteries.

11. ON Battery: The UPS is running in “ON-BATTERY mode” (backup

mode), the internal batteries supply power.
