2 Overview
This chapter mainly introduces the UPS's model meaning, features, structure, work principle, etc.
2.1 Product Intro
10-40kVA series UPS is whole high frequency, pure online, double-conversion, smart product..The
system is perfect power security for le server, enterprise server, center server, mirco-computer,
concentrator, telecom system, data center and others that require high quality power protection. They
are widely used in many key business areas, such as post, nance, network, stock, railway, etc.
2.1.1 Model Meaning
If there is no "/B",that means the UPS can be single used only.
Three-phase input three-phase output (three in three out) is 33 mode, three-phase input single-phase
output (three in one out) is 31 mode, single -phase input single-phase output (one in one out) is 11 mode.
2.1.2 Features
Completely digitalized smart control
The UPS support various input and output mode, such as 33 mode, 31 mode, 11 mode. The UPS can
monitor the grid frequency (50Hz/60Hz) and self-adapt the frequency. The output voltage can be set to
208V/220V/230V/240V, which makes amore exible usage.
Energy conservation and high efciency
Adopts three-level inverter technology and PFC control technology, the output voltage wave is perfect
and the whole efciency can be 96%, the input power factor is greater than 0.99, which greatly
improves the use ratio of electric energy and reduces the load of power grid.
Smart fan speed control
The fan speed is adjusted automatically in accordance with the load status, which prolong fan life and
reduce noise.

2Overview User Manual

ECO energy conservation mode design
The UPS is designed with ECO energy conservation mode. When the grid is good, if the UPS operating
in this mode, the bypass prior to output, and the efciency can be 99%.When the bypass voltage or
frequency out of normal range and cannot satisfy the user’s power supply requirement, it will switch
to inverter output, which guarantee the reliability of power supply and also, save energy.
Low mains input voltage
Adopt the independent rapid detection technology. When output load is small, even the battery voltage
is 80V, which is the main slow limit, the battery still doesn't discharge. Therefore, in the mains mode,
all output power gets from the grid, which is to ensure the battery in 100% energy storage status, and
at the same time, reduce the battery discharge times and prolong the service life.
Tower-mounting and rack-mounting
User can select tower-mounting or rack-mounting the UPS according to use space, the LCD also can
display corresponding direction on the basis of placement mode.

The UPS includes rectication/PFC, inverter, charger, bypass static switch etc function module, the
input power includes mains input, bypass input, battery input, the output mode includes inverter output,
bypass output and maintenance bypass output (if equipped).
When mains normal, the rectier starts and the charger charges the battery at the same time. When
UPS off, if bypass normal, the system turns to bypass output; when UPS on, the mains boosts by
rectication/PFC and output DC bus voltage, and then go through inverter and output pure sine-wave
AC power, the output turns to inverter output to load from bypass output (if equipped).
When mains abnormal, the battery voltage boosts by rectication/PFC and output DC bus voltage, and
then go through inverter and output pure sine-wave AC power to load. When mains recover normal,
the UPS turns to mains mode from battery mode automatically.
2.2.2 Work Mode
There are 5 work modes of the UPS: normal mains power supply mode, battery inverter mode, bypass
power supply mode, ECO power supply mode and maintenance bypass power supply mode.

mains power supply mode. If the mains always abnormal and the battery is running up, the UPS will
send sound and light alarm and stop working till battery low-voltage point. At that time, the buzzer
long beeps to alarm, the power for load powers down. Under the circumstance of mains power outage
completely, the UPS will shut down about 1min later automatically and close the power of the UPS to
avoid the battery discharge slimly, thus to protect the service life of battery. Once the mains recovers,
the UPS will start automatically and turn to normal mains power supply mode.

Bypass power supply mode
Under the circumstance of bypass voltage normal, when UPS off or fault (such as inverter output
overload, over-current surge or IGBT over-temperature etc) while UPS on, the UPS will output by
bypass. When UPS on and the fault removed, it will turn to inverter output again. If the same fault
occurs more than 5 times in a short time, the UPS protects and output by bypass until power off
manually or power down and remove the fault, restart the UPS and then it will recover normal work.

ECO power supply mode (just suitable for single UPS)
At the ECO mode, when bypass voltage normal, the power for load is prior supplied by bypass, when
bypass voltage abnormal, the power for load turns to inverter. ECO mode is an economic operation
mode. For the load which does not require high quality, user can select ECO mode to reduce the energy
consumption. At the ECO mode, the UPS efciency can be 99%.
Maintenance bypass power supply mode (suitable for the system with distribution module)
When the UPS needs to be maintained and the power supply for load cannot be interrupted, user can
shut down the inverter and make the UPS works in bypass status, then switch on the maintenance
bypass breaker and switch off the mains input breaker and bypass input breaker, output breaker. During
the transforming of manual maintenance bypass,AC power is supplied for load by maintenance bypass
breaker. At this time, the inner UPS has no electricity, maintainer can perform the maintenance safely.
