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 managem ent software is also optional. The function and efficiency are superior to the traditional UPS.

Fig. 2.1 is the ha rdware block diagram of the UPS.

The UPS operation is desc ribed as below: When the utility power is applied into the UPS, it was di vided into two ways a fter 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 c harge 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”.

DELTA DOC CENTER

In case the utility power fail, the AC-DC converter and charger will be off duty. The

SHEET 7 TO 8

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 suppl ies the designated power to al l the control circuits. Because the DC-AC inverter is always working, the DC-DC convert er can work rapidly

and replace the AC-DC converter while the utility power fails. Furthermore, the bypass relay continuously keeps in the posi tion of inverter output to supply the regulated power for the load. There i s no power failure to loading e quipment.

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 out standing protection features, the unit keeps your applications safe and running smoothl y a t 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 wit h 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 ti me provide best protection. With a built-in s urge, 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” prote c tion.

Intelligent design

Integrated with a microprocessor, the UPS is able to perform intelligent functions. The UPS triggers over-voltage protection function and transfers to “ 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 volta ge range means less battery power usage frequency and longer battery life-span. Besides, programmable outlet design, suitable for power ma nagement, is als o 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 cont rol during power line blackout will restart automatically when AC power recovers. Using our automatic frequency sensing function to match input and out put 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 e vent of output overload.

Safety approvals

The UPS has passed va rious 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 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
