I. GENERAL DESCRIPTION
1.1 Introduction
VISION DSP0.9 Series Uninterruptible Power Supplies are double-conversion; on-
line UPS’s 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.
VISION DSP0.9 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 DSP0.9 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 DSP0.9 Series UPSs, a DSP controlled 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 DSP0.9 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 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.

phase supply are used as the bypass inputs under normal conditions, if there is not a separate
bypass supply (split bypass).
If there is a separate 3- phase AC supply for bypass (Split Bypass):
a-) Remove the links between K4 – K5, K6 – K7 and K8 – K9.
b-) Connect the phases of the bypass source U2, V2 and W2 to K5, K7 and K9 respectively.
c-) Connect the Neutral (N2) of the Bypass source to K11.
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/fuse before making any connection on the batteries.
The batteries associated with the UPS equipment are usually contained in a purpose-built battery
cabinet. In DSP0.9 Series 40-60 KVA UPSs, there is enough space for 60 pieces of 12V 7Ah
maintenance free batteries.
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 (S5)
before checking all connections and before starting the UPS. In DSP0.9 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 tap connection to the NEUTRAL (N1-N2) internally.
NOTE THAT SEPARATE CABLES FROM EACH BATTERY GROUP SHOULD BE CONNECTED
TO K2 TERMINALS TO FORM THE MIDPOINT CONNECTION.
WARNING!!! NEVER TURN ON S5 (BATTERY FUSE) WITHOUT CENTER POINT CONNECTION TO
K2.
