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 700VA, 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.

High power density

Other than traditional UPS adopting 0.7 output power factor, the UPS uses the latest

technology and highest quality components giving output power factor up to 0.8.

Compared to other UPS (1000VA/700W), these UPS series boosts a 12% more output

power. This UPS with its compact size, generates higher power density thus giving

convenience to the users. Moreover, through the use of advanced technology, the UPS

efficiency increases to more than 87%. Compared with other traditional UPS with only 80

to 85% efficiency, this UPS produces greater electric power efficiency at less electric

costs.

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 sinewave 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 which travel along communication lines, therefore

providing you a complete “back door” protection.

DELTA DOC CENTER

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 300V for 200V-series. In addition, the UPS can accept large

voltage variation of 65V to 138V for 100V-series or 130V to 275V for 200V-series.

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.

Considerate design

Battery start function allows startup of the UPS even when there is no AC line available.

In addition, the UPS which was shut down by remote control during power line blackout

will restart automatically when AC power recovers. Using our automatic frequency

sensing function to match input and output frequency, users don't need to set either 50Hz

or 60Hz. Other features, such as UPS self-diagnosis and flexible external battery pack,

are also included.

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.

Safety approvals

The UPS has passed various safety regulations. UL/cUL, TUV/EMC, TUV/GS, CE mark

and other safety approvals, proves that the UPS is a safe reliable solution to your power

problems.

Network Management

Build-in communication interface port supporting RS232 and Dry contact protocols

enhances the reliability and manageability of the UPS over all major operating systems,

including Windows 95/98, Windows NT, Netware, Unix, and others. Besides, the UPS

also supports the Simple Network Management Protocol and Hyper Text Transfer

Protocol via plugging a SNMP/HTTP adapter into the build-in SNMP slot.
