1. INTRODUCTION

First of all, we wish to thank each of you whom purchases our premier UPS F3000
RAID of CROSS TEC
The name of Frontier was originated from the key words of our company motto, which
is

"We, each and every member of

CROSS TEC(www.crossups.com)

shall head toward to
reach the top in the field as we try together with the original idea and the research
investment, firmly based on the concord and the sincerity of our good will"

. Those
keywords are Electricity, Sincerity, Concord, Original idea, Research investment,
and Top. As expressed in the name of FRONTIER itself, F3000 RAID

UPS system

serves as the guardian of all the sensitive power equipment including computers &
telecommunication systems and computerized instruments, and as well as our
confident and widely known representative product.

The F3000 RAID

Uninterruptible Power System

of CROSS TEC. is a truly advanced 3-phase on-line
sine wave UPS which Utilizes new power electronic technology such as Pulse Width
Modulation by IGBT(Insulated Gate Bipolar Transistor), and is designed to offer
high efficiency, low operational noise, compact size, better reliability, and easy
access for maintenance and service to our most valuable customer.

We put all together of our inspiration, intuition, energy, effort, and resources
in our premier F3000

-3000 Uninterruptible Power Supply System

.

2. SYSTEM DESCRIPTION

2.1. Foreword

This UPS system facilitates sine wave Pulse Width Modulation which
instantaneously controls the waveform to supply the uninterrupted constant
voltage and constant frequency balanced 3-phase AC power to the critical load
for smooth operation and fortified protection against unstable commercial
power failure such as outage, sag, surge, voltage transient, frequency change,
flicker, and etc.

2.2. Composition and Functions

The F-

3000 system

is composed of numerous parts as follows,

- Input Transformer

- Rectifier & Battery Charger

- Inverter

- Output Transformer

- Static Switch

- Control Circuitry

- Digital Display

2.2.1. Input Transformer

This transformer is manufactured as H class dry type. The output voltage is
designed to correspond the input voltage of inverter and charging voltage of
battery, and the output current, to sufficiently match the sum of the
charging current and the rated current of inverter.

2.2.2. Rectifier & Battery Charger

This unit includes the thyristor module, heat dissipation board, and many
other components. It will convert input AC power to DC power, supply the
inverter, and simultaneously charge the battery with the best condition
possible.

Also, the filtering circuit composed of reactor and condenser, is employed

to filter out the ripple characteristics contained in the rectified DC power,
in order to yield the best possible DC power.

2.2.3. Inverter

This unit contains IGBT (Insulated Gate Bipolar Transistor) module, heat
dissipation board, rapid firing fuse for the semi-conductor protection and
other relevant component. The high frequency switching and the sine wave
Pulse Width Modulation, are utilized in this unit. The inverter will
revert the DC power obtained from rectifier to PWM AC output, and then the
AC filter will make it very similar to the balanced sinewave AC voltage to
supply the critical load.

2.2.4. Output Transformer

The primary lead shall be connected to inverter and the secondary to output
in this isolation transformer. It is specially designed to contain the
reactance and partially serves as output filter.
Also, it minimizes the current harmonics, and maximizes efficiency. The
input and output voltage and frequency are synchronized by phase lock loop
oscillator. The synchronized transfer units are placed at the bypass line
and at the inverter section.

2.2.5. Static Switch

This unit operates as an automatic transfer device between inverter and
bypass feed. At the moment of detection of any abnormal operation in
inverter or over-load condition, the static switch will simultaneously
transfer the power supply to bypass feed (commercial power), not to
interrupt the load operation. When the inverter operation returns to
normal, the static switch will then retransfer supply line to inverter,
again without any interruption.
In order to avoid the possible rush current evolved from the phase difference,
this unit is constituted with only semi-conductors.

2.2.6. Control Circuitry

This unit consists of inverter control, alarming circuit, static switch
control, and etc. It is designed to operate though the internal unexpected
voltage transient intervenes. Its power comes from the battery by DC/DC
converter, and thus, power outage or start-up peak current would not affect
the control circuitry operation.
