I. GENERAL DESCRIPTION
1.1 Introduction
TESCOM DXA3000 Series Uninterruptible Power Supplies are double-conversion;
3-level on-line UPSs manufactured with the latest IGBT and PWM technology, to produce an
uninterruptible, fully DSP (Digital Signal Processor) controlled pure sine wave output to
critical loads.
TESCOM DXA3000 Series units are 3-phase in/3-phase out devices, and they are
installed between a three phase critical load, and a 3-phase+N mains supply
The advantages of using DXA3000 UPS:
•Power blackout protection:
If the mains power fails, the UPS continues to supply the critical load using the
energy stored in its batteries, keeping the load immune from power disturbances.
•Increased power quality:
The UPS has its own internal voltage and frequency regulating software, which
ensures that, its output to the critical load is maintained within close tolerances, independent
of voltage and frequency variations on the mains power lines.
•Fully digital control by three DSP controller for each UPS:
The UPS is controlled by 3 independent DSP chips which are communicating each
other continuously. Rectifier, Inverter and User Interface modules have separate DSP’s to
achieve the highest performance. Each DSP module has many parameters to control and
monitor the system to have the best electrical power output and to help diagnostic.
•Increased noise rejection:
By rectifying the input AC power to DC power and then converting it back to AC
(Double-Conversion) any electrical noise present on the input mains supply line is effectively
isolated from the UPS output. Therefore the critical load is supplied with only clean and
uninterrupted AC power.

1.2.1 DESCRIPTION OF BLOCKS
RECTIFIER: In DXA3000 Series UPSs, a DSP controlled, 3-Level IGBT rectifier with PWM technique is
used to increase input power factor (PFC) and to decrease input current harmonics (THDI).
The IGBT rectifier accepts 3-phase AC input and produces a dual polarity DC voltage for both supplying
the inverter and charging the batteries.
BATTERIES: Batteries are used as reserve DC power supply for the Inverter in case of mains failure. In
DXA3000 Series, batteries are connected in series with a center-tap output to obtain a dual polarity DC
supply.
Batteries are discharged by the inverter during mains failure. The discharged batteries are re-charged by
the IGBT Rectifier on a constant voltage / current limiting basis, if AC mains power is available.
INVERTER: It is manufactured by using the latest 3-Level IGBT and DSP (Digital Signal Processing)
technologies, and Pulse Width Modulation (PWM) technique. The Inverter converts the DC BUS voltage
supplied by the IGBT Rectifier and / or the batteries into a well regulated, fully digital controlled 3-phase AC
voltage with fixed voltage and frequency.
The output of the inverter is used to supply the critical loads connected to the UPS output.
STATIC TRANSFER SWITCH (STATIC BYPASS): This is an electronically controlled transfer switch,
which enables the critical load to be connected either to inverter output or to by-pass power source. During
normal operation, the load is supplied by the inverter output, but in case of an overload or a UPS failure it is
automatically transferred to the bypass source without any interruption.
MAINTENANCE BYPASS SWITCH (MBS): This is a manually controlled mechanical switch, which is used
to supply the critical load, using the bypass source, when the UPS is shut down for maintenance or
troubleshooting purposes.
The load is unprotected against mains supply disturbances and black-outs when it is connected to either
static or maintenance bypass supply.
1.2.2. OPERATING CONDITIONS OF UPS
UPS may be in one of the following operating conditions:
A. Normal Operation (If Mains supply is available):
All fuses and power switches are closed (except the Maintenance Bypass Switch), and the load is supplied
by the Inverter Output. During normal operation, the Rectifier supplies DC power to the Inverter and
charges the Batteries at the same time.
B. Battery Operation :
The Batteries are connected to the Rectifier output. In case of a mains failure (mains power outage or AC
input voltage out of tolerance), the Rectifier stops operating and the DC voltage necessary for the inverter
operation is supplied by the batteries. Therefore the AC voltage output supplying the critical load is not
interrupted, until the batteries are fully discharged. At the end of the discharging time the inverter is turned
off and it start again automatically, together with the rectifier, when the mains power is restored, and the
UPS returns o normal operation. For UPS with a split bypass source, at the end of discharging time, static
transfer switch transfers the load to the split bypass source without interruption if the split bypass source is
available and in acceptable tolerances about voltage and frequency, as still the rectifier input is not
available.
The Rectifier is also turned off and inverter operates on batteries during automatic or manual battery test
procedure.
C. By-Pass Operation :
If the Inverter output is overloaded or in case of a problem in the UPS, the static switch transfers the load to
the bypass supply without any interruption, provided that the bypass supply is available and within the
tolerated limits regarding voltage and frequency. At the end of the overloading period, if the fault condition
is restored, static switch transfers the critical load again to the inverter output. Note that, during operation
from the bypass supply, the critical load may be effected by any possible disturbances or power failure in
the bypass supply.

NOTES :
•As shown on the power cable connection diagram of the UPS, U1, V1 and W1 phase of the incoming 3
phase supply are also used as the bypass inputs under normal conditions (U1, V1, W1 and U2, V2, W2 are
the same in this case).
•If there is a separate 3- phase AC supply for bypass (Split Bypass):
a-) Remove the links between AC INPUT SW (S1) and BYPASS INPUT SW (S2)
b-) Connect the phases of the bypass source U2, V2 and W2 to the input terminals of S2
(Keeping the AC input phases U1, V1, and W1 connected to S1 terminals)
c-) Connect the Neutral (N2) of the Bypass source to.NEUTRAL BUSBAR
Note that the Neutral of the 3 phase input supply (N1) and the Neutral of the 3-phase bypass supply (N2)
must always be connected together to form the Neutral of the AC output.
2.7 Battery Installation
WARNING!!! Be careful while connecting batteries.
ATTENTION!!! Open the battery switch before making any connection on the batteries.
The batteries associated with the UPS equipment are usually contained in a purpose-built battery cabinet.
External batteries are used in DXA3000 Series 100,120,160,200 and 250 kVA UPSs, there is no space for
internal batteries in UPS cabinet.
Where battery racks are used, they should be sited and assembled in accordance with the battery
manufacturer’s recommendations. In general, batteries require a well-ventilated, clean and dry environment
at reasonable temperatures to obtain efficient battery operation.
In general a minimum space of 10 mm must be left on all vertical sides of the battery block. A minimum
clearance of 20 mm should be allowed between the cell surface and any walls. All metal racks and cabinets
must be earthed.
1. Unpack each battery and check its terminal voltage with a suitable load. Any battery with terminal
voltage less than 10,5V must be charged before installation.
2. Please check the battery connecting hardware and documents. (cables, trays, connection diagrams)
3. Please locate suitable number of batteries on each rack, according to the battery installation and
connection diagram given with the unit.
4. Start locating the batteries from top to the bottom on the racks.
5. Be careful about the connection between the racks and polarities.
6. After interconnecting the batteries, connect “+”, “0” and “-“ leads of the batteries to the battery input
terminals on the UPS. Be careful to connect the batteries correctly and do not turn on the battery
switch/fuse on the external battery cabinet before checking all connections and before starting the
UPS. In DXA3000 Series UPS, 60 blocks of batteries are connected in series, in such a way that they
form two strings of batteries with opposite polarity; with a center point connected to the NEUTRAL
BUSBAR.
NOTE THAT SEPARATE CABLES FROM EACH BATTERY GROUP SHOULD BE CONNECTED TO
THE NEUTRAL BUSBAR TO FORM THE MIDPOINT CONNECTION.
WARNING!!! NEVER TURN ON BATTERY SWITCH/FUSE ON THE EXTERNAL BATTERY CABİNET
WITHOUT CENTER POINT CONNECTIONS TO THE NEUTRAL BUSBAR.
