2. INTRODUCTION
Congratulations on your choice of the UPS uninterruptible power system(UPS), the
UPS comes in nominal power ratings of 6000VA,10000VA,15000VA and 20,000VA. It is
designed to provide conditioned power to microcomputers and other sensitive electronic
equipment.
When it is generated, alternating current is clean and stable. However, during
transmission and distribution it may be subject to voltage sags, spikes and complete power
failure that may interrupt computer operations, cause data loss and even damage
equipment. The UPS protects equipment from these disturbances.
The UPS is a compact, on-line UPS. An on-line UPS continuously conditions and
regulates its output voltage, whether utility power is present or not. It supplies connected
equipment with clean sine wave power. Sensitive electronic equipment operates best from
sine wave power.
For ease of use, the UPS features a LCD display to indicate all information for UPS,
and provide kinds of function buttons.

3. SYSTEM DESCRIPTION
3.1 Transient Voltage Surge Suppression (TVSS) and EMI/FRI Filters
These UPS components provide surge protection and filter both electromagnetic
interference (EMI) and radio frequency interference (RFI). They minimize any surge or
interference present in the utility line and keep the sensitive equipment protected.
3.2 Rectifier/Power Factor Correction (PFC) Circuit
In normal operation, the rectifier/power factor correction (PFC) circuit converts utility AC
power to regulated DC power for use by the inverter while ensuring that the waveform of the
input current used by the UPS is near ideal. Extracting this sine wave input current achieves
two objects:
zThe utility power is used as efficiency as possible by the UPS.
zThe amount of distortion reflected on the utility is reduced.
This results in cleaner power being available to other devices in the building not being
protected by the UPS.
3.3 Inverter
In normal operation, the inverter utilize the DC output of the power factor correction
circuit and inverters it into precise, regulated sine wave AC power. Upon a utility power
failure, the inverter receives its required energy from the battery through the DC-to-DC
converter. In both modes of operation, the UPS inverter is on-line and continuously
generating clean, precise, regulated AC output power.

System Description
True Online 6-20k UPS User Manual 8
3.4 Battery Charger
The battery charger utilizes energy from the utility power and precisely regulates it to
continuously float charge the batteries. The batteries are being charged whenever the UPS
is connected to utility power.
3.5 DC-to-DC Converter
The DC-to-DC converter utilizes energy from the battery system and raises the DC
voltage to the optimum operating voltage for the inverter. The converter includes boost
circuit which is also used as PFC.
3.6 Battery
The 6K/10K Standard include value-regulated, non-spoilable, lead acid batteries inside.
To maintain battery design life, operate the UPS in an ambient temperature of 15-25°C.
3.7 Dynamic Bypass
The UPS provides an alternate path for utility power to the connected load in the
unlikely event of a UPS malfunction. Should the UPS have an overload, over temperature or
any other failure condition, the UPS automatically transfers the connected load to bypass.
Bypass operation is indicated by an audible alarm and illuminated amber Bypass LED. To
manually transfer the connected load from the inverter to bypass, press the ON/OFF button
or Manual Bypass button once.
NOTICE：The bypass power path does NOT protect the connected equipment from
disturbances in the utility supply.
