2. Product Introduction
2.1 Introduction
The UPS supplies stable and uninterrupted power for the important load. It can
eliminate the power supply surge, instantaneous high/low voltage, harmonic and
frequency offset pollution, to provide high quality electrical energy to costomers.
2.2 System Configuration
The Tower UPS is configured by the following part: Rectifier, Charger, Inverter,
Static Switch and Manual Bypass Switch. One or several battery strings should be
installed to provide backup energy once the utility fails. The UPS structure is shown
in Fig. 2-1.
Fig. 2-1 UPS Configuration
2.3 Operation Mode
The UPS is an on-line, double-conversion UPS that permits operation in the following
modes:
Normal mode
Battery mode
Bypass mode
Maintenance mode (manual bypass)
ECO mode
Auto-restart mode
Frequency Converter mode
Self Aging Mode
2.3.1 Normal Mode
The inverter of power modules continuously supply the critical AC load. The
rectifier/charger derives power from the AC mains input source and supplies DC
power to the inverter while simultaneously FLOAT or BOOST charging its associated
backup battery.
USER MANUAL TEOS 400E-EB PRO 10-30kVA

5
Fig 2-2 Normal mode operation diagram
2.3.2 Battery Mode
Upon failure of the AC mains input power, the inverter of power modules, which
obtain power from the battery, supply the critical AC load. There is no interruption in
power to the critical load upon failure. After restoration of the AC mains input power,
the “Normal mode” operation will continue automatically without the necessity of
user intervention.
Fig 2-3 Battery mode operation diagram
Note
With the function of Battery cold start, the UPS may start without utility. See more detail in
section 5.1.2.
2.3.3 Bypass Mode
If the inverter overload capacity is exceeded under Normal mode, or if the inverter
becomes unavailable for any reason, the static transfer switch will perform a transfer
of the load from the inverter to the bypass source, with no interruption in power to the
critical AC load. Should the inverter be asynchronous with the bypass, the static
switch will perform a transfer of the load from the inverter to the bypass with power
interruption to the load. This is to avoid large cross currents due to the paralleling of
unsynchronized AC sources. This interruption is programmable but typically set to be
less than 3/4 of an electrical cycle, e.g., less than 15ms (50Hz) or less than 12.5ms
(60Hz). The action of transfer/re-transfer can also be done by the command through
monitor.
USER MANUAL TEOS 400E-EB PRO 10-30kVA

Fig. 2-4 Bypass mode operation diagram
2.3.4 Maintenance Mode (Manual Bypass)
A manual bypass switch is available to ensure continuity of supply to the critical load
when the UPS becomes unavailable e.g. during a maintenance procedure. (See
Fig.2-5).
Fig .2-5 Maintenance mode operation diagram
Danger
During Maintenance mode, dangerous voltages are present on the terminal of input, output and
neutral, even with the LCD turned off.
2.3.5 ECO Mode
To improve system efficiency, UPS rack system works in Bypass mode at normal
time, and inverter is standby. When the utility fails, The UPS transfers to Battery
Mode and the inverter powers the loads.
USER MANUAL TEOS 400E-EB PRO 10-30kVA

7
Fig.2-6 ECO Mode operation diagram
Note
There is a short interruption time (less than 10ms) when transfer from ECO mode to battery mode,
it must be sure that the interruption has no effect on loads.
2.3.6 Auto-restart Mode
The battery may become exhausted following an extended AC mains failure. The
inverter shuts down when the battery reaches the End of Discharge Voltage (EOD).
The UPS may be programmed to “System Auto Start Mode after EOD”. The system
starts after a delay time when the AC mains input recovers. The mode and the delay
time are programmed by the commissioning engineer.
2.3.7 Frequency Converter Mode
By setting the UPS to Frequency Converter mode, the UPS could present a stable
output of fixed frequency (50 or 60Hz), and the bypass static switch is not available.
2.3.8 Self Aging Mode
If users want to burn in UPS without load, could set the UPS as Self Aging Mode, in
this mode, the current flow through rectifier, inverter, and back to input through
bypass. It needs only 5% loss to burn in UPS with 100% load.
