3 GENERAL UPS DESCRIPTION
The UPS use IGBT technology with a high changeover frequency in order to allow a low
distortion of the current re-injected into the supply line, as well as high quality and stability of
output voltage. The components used assure high reliability, very high efficiency and
maintenance easiness.
3.1 TYPOLOGY
The UPS are on-line, double conversion; the inverter included in the UPS always supplies
energy to the load, whether mains is available or not (according to the battery autonomy time).
This configuration guarantees the best service to the User, as it supplies clean power
uninterruptedly, ensuring voltage and frequency stabilization at nominal value. Thanks to the
double conversion, it makes the load completely immune from micro-interruptions and from
excessive mains variations, and prevents damage to critical loads (Computer - Instrumentation -
Scientific equipment etc.).
Output voltage present
The line connected to the UPS output is energized even during mains failure,
therefore in compliance with the prescriptions of IEC EN62040-1-2, the installer will
have to identify the line or the plugs supplied by the UPS making the User aware of
this fact.
Picture 1 – Block diagram
3.2 SYSTEM DESCRIPTION
3.2.1 Rectifier
It converts the three-phase voltage of the AC mains into continuous DC voltage.
It uses a three-phase fully-controlled IGBT bridge with a low harmonic absorption.
The control electronics uses a 32 bit P of latest generation that allows to reduce the
distortion of the current absorbed by mains (THDi) to less than 5%. This ensures that the
rectifier does not distort the supply mains, with regard to the other loads. It also avoids cable
overheating due to the harmonics circulation.
The rectifier is so sized as to supply the inverter at full load and the battery at the maximum
charging current.

Manuel de l'utilisateur de l'UPS
Utilizzo dell’UPS
OMD10074 REV. C 11
3.2.2 Inverter
It converts the direct voltage coming from the rectifier or from the DC battery into alternating
AC voltage stabilized in amplitude and frequency.
The inverter uses IGBT technology with a high changeover frequency of approximately 15
kHz.
The control electronics uses a 32 Bit P of latest generation that, thanks to its processing
capability, generates an excellent output sine-wave.
Moreover, the fully digital control of the output sine-wave allows to achieve high
performances, among which a very low voltage distortion even in presence of high-distorting
loads.
3.2.3 Battery and battery charger
The battery is installed outside the UPS. It is generally housed in an external battery cabinet.
The battery charger logic is completely integrated in the rectifier’s control electronics.
The battery is charged, according to the DIN 41773 Standard, every time it has been
partially or completely discharged. When its full capacity is restored, it is kept floating so as to
compensate for any autodischarge.
3.2.4 Static bypass
The Static Bypass allows to transfer the load between Inverter and Emergency Mains, and
vice-versa, in a very short time, and uses SCR’s as power commutation elements.
3.2.5 Manual bypass
The Manual Bypass is used to cut off the UPS completely, supplying the load directly from
the input mains in case of maintenance or serious failure.
Follow the procedures contained in the manual
The sequence of manual bypass switching and return must be carried out with
respect to the procedure indicated in the installation and start-up section. The
manufacturer cannot accept responsibility for damages arising from incorrect
operation.
External manual bypass
In the UPS systems of the KEOR HP 400-800kVA, the manual bypass isolator is
optional and outside the unit.

3.3 OPERATING STATUS
The UPS has four different operating modes, as described below:
Normal operation
Bypass operation
Battery operation
Manual bypass
3.3.1 Normal operation
During normal operation all the circuit breakers/isolators are closed, except for MBCB
(maintenance bypass).
The rectifier is supplied by the AC three-phase input voltage which, on its turn, feeds the
inverter and compensates mains voltage as well as load variations, keeping the DC voltage
constant. At the same time, it keeps the battery charged (floating or boost charge depending on
the battery type). The inverter converts the DC voltage into an AC sine-wave with stabilized
voltage and frequency, and also supplies the load via its static switch SSI.
Picture 2 – Normal operation
3.3.2 Bypass operation
The load can be switched to bypass either automatically or manually. The manual
changeover is due to the BYPASS SWITCH which forces the load to bypass. In case of failure
of the bypass line, the load is switched back to inverter without interruption.
Picture 3 – Load supplied by bypass

UPS user manual
Manuel de l'utilisateur de l'UPS
Utilizzo dell’UPS
OMD10074 REV. C 13
3.3.3 Battery operation
In case of power failure or rectifier fault, the battery feeds the inverter without interruption.
The battery voltage drops based on the amplitude of the discharging current. The voltage drop
has no effect on the output voltage, which is kept constant by changing the PWM modulation.
An alarm is activated when the battery is near the minimum discharge value.
In case the supply is restored before the battery is completely discharged, the system will be
switched back to normal operation automatically. In the opposite case, the inverter shuts down
and the load is switched to the bypass line (bypass operation). If the bypass line is not available
or is out of tolerance, the loads supply is interrupted as soon as the battery reaches the
discharge limit threshold (black-out).
As soon as the supply is restored, the rectifier will recharge the battery. In the standard
configuration, the loads are supplied again via static switch SSB when mains is available again.
The inverter is restarted when the battery has partially restored its capacity.
The system restart from the black-out condition can be customized based on the
requirements of the plant, in three different modes:
Bypass loads are supplied as soon as the bypass line is available (factory
configuration).
Inverter loads are supplied by the inverter (even if the bypass line is
available) when the battery voltage has reached a programmed
threshold, after the rectifier restart.
Man. Inverter the output supply is NOT restored automatically. The system
requires a confirmation to restart which can only be done manually
by the user via the front panel.

3.3.4 Manual bypass
The manual bypass operation is necessary whenever the UPS functionality is tested, or
during maintenance or repair work.
During the manual bypass due to repair or maintenance, the UPS is completely shut down
and the load is directly supplied by the bypass line.
Follow the procedures contained in the manual
The sequence of manual bypass switching and return must be carried out with
respect to the procedure indicated in the installation and start-up section. The
manufacturer cannot accept responsibility for damages arising from incorrect
operation.
