3 INTRODUCTION
Congratulations on your choice of the uninterruptible power system(UPS), the series comes in nominal power ratings of
6000VA,10000VA. 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 series protects equipment from these disturbances.
The series is a compact, rack-mount, 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 series features a LCD display to indicate all information for UPS, and provide kinds of function buttons.
The ups contains a removable power distribution box factory-attached that includes a manual bypass switch allow AC power to
continue to flow from the utility input to the load while the box is removed from the UPS.

4 SYSTEM DESCRIPTION

4.1 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.
4.2 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:
 The utility power is used as efficiency as possible by the UPS.
 The 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.
4.3 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.
4.4 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.
4.5 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.
4.6 Battery
The ups L include value-regulated, non-spoilable, lead acid batteries outside. To maintain battery design life, operate the UPS in an
ambient temperature of 15-25°C.
4.7 Dynamic Bypass
The ups provide 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.
NOTE：The bypass power path does NOT protect the connected equipment from disturbances in the utility supply.
