4.3. GENERAL DESCRIPTION.
The SLC ADAPT series is classified as an on-line double-
conversion uninterruptible power supply with DSP control and
three-level IGBT inverter technology, modular topology and
great flexibility.
Reliability: The DSP control associated with three-level PWM
technology increases the performance of the system and, together
with the redundancy of the modules, manages to increase the
availability of power to the critical loads, a parameter that
contributes to achieving a good TIER classification for the entire
system.
Availability: Its hot-swap modules can be added or replaced
during operation, thereby improving mean time to repair
(MTTR) and reducing maintenance costs. Moreover, both the
control display and the bypass module can be replaced without
affecting the operation of the device. In addition, the sys-
tem’s remote management, which can be integrated into any
platform, also makes operation easier. The extensive backup
options available, along with smart battery charging, ensure
continuous operation of the protected critical loads.
Modularity: This allows simple configurable solutions from
30 to 1500 kVA by installing 30 or 50 kVA modules in the 6-slot
(30 kVA modules) or 10-slot cabinets. As composite solutions,
a maximum of 30modules can be paralleled to obtain higher
power systems or N+n structures. Either way, it is only possible
to install identical modules in the same cabinet and/or parallel
cabinets with modules of equal power. This enables gradual
growth and scaling for future expansion depending on the
need for pay-as-you-grow protection, improving the total cost
of ownership (TCO) and providing a high level of flexibility. At
operational level, a cabinet consisting of ‘N’ modules connected
in parallel is considered a single UPS.
Any expansion or structural change to the number of modules
is possible even during normal operation and without needing
to shut down the hot-swappable system, all with the simple
use of a screwdriver to remove or screw the fixing screws of
the module(s). Although all of the UPS’s modules incorporate a
battery charger that can allocate up to 20% of its rated power
to maintaining them at an optimum charge level depending on
the type and number of elements, 50 A battery charger modules
are available to be installed solely with the 30 kVA SLC ADAPT
modules. As many charging modules as considered appropriate
can be installed, but this will be to the detriment of the total
number of UPS modules and, consequently, the total power of
the system, which will be reduced.
Backup: The capacity of the batteries determines the backup
time of the system when replacing the usual source of energy
during mains failures. The accumulator bank is always common
to any system mounted in the same cabinet. Batteries owned by
the customer or supplied with the UPS, depending on different
factors in addition to the power and/or backup requested, can
be installed in a back or one or more cabinets, always external
to the UPS itself.
4.3.1. Introduction.
SLC ADAPT series UPSs basically consist of:
•6- or 10-slot cabinet to install the power modules.
•Power modules consisting of the following blocks:
AC/DC PFC rectifier.
Battery charger.
DC/AC inverter.
Digital control and UPS management.
•Centralised bypass module: control of UPS and parallel pa-
rameters.
•Maintenance bypass.
•Control panel with touch screen (see section X for more
information).
•Batteries (number, type and location depending on the
backup time).
•Self-supporting 36 and 46U cabinets for the placement of
the different modules.
4.3.2. Conceptual diagram of the system.
The modular UPSs of the SLC ADAPT series consist of power
modules, a bypass and monitoring module, and a cabinet with
a range of disconnectors for Input, Bypass Output and Manual
Bypass. The 180 and 300 kVA UPSs only have a manual bypass
switch. One or more battery branches should be installed to
provide backup power in the event of a power failure. The
structure of the UPS is shown in Fig. 14.

The batteries are represented in

batteries can be supplied in a
separate cabinet, in a bank or not
supplied if the customer already
has them.

SLC ADAPT UNINTERRUPTIBLE POWER SUPPLY (UPS)USER'S MANUAL

18 SALICRU
Fig. 14 shows, byway of example, a single-line diagram of the
device with three-phase input and output.
All modules in the cabinet are structured according to the same
criteria, terminals for the power supply of the PFC rectifier and
independent static bypass, and input, output, static bypass
and manual bypass disconnectors. However, unless otherwise
requested, for separate networks originally from the factory,
the terminals of the phases of both blocks are connected by
means of strips to provide a single common input.
When separate power supplies are required, it is
obligatory to remove the strips between the phases of
both blocks before connecting the power cables, leaving the
connection strip of the neutral terminals.
4.3.2.1. Power modules (PM).
Power modules are the basic core of the entire SLC ADAPT
system. Apart from the static bypass block and LCD touch
screen, each power module contains all of the converters and
functionalities of a traditional UPS. Since this device consists
of a number of variable modules depending on the cabinet
used, a multi-parallel system is obtained with the behaviour
equivalent to that of a single mono-bloc UPS and the advan-
tages of a modular UPS.
The system supplies power to the critical load (such as com-
munication and data processing equipment) with uninterrupted
high quality AC power. The power supplied by the unit is stable,
without voltage and/or frequency variations and free from
other disturbances such as cuts or micro-cuts, sine wave al-
terations, electrical noise, anomalies commonly present in the
commercial AC network.
This is achieved through the double-conversion high frequency
Pulse Width Modulation (PWM), in combination with a digital
control based on a Digital Signal Processor (DSP), which pro-
vides high reliability and availability.
As can be seen in Fig. 14, the AC power supplied to the UPS
input is converted into DC voltage. This voltage supplies a con-
verter that transforms the voltage type from DC to AC, clean of
disturbances and variations of the AC input mains. If this fails,
the PFC rectifier changes the input source of the AC mains to
that of the batteries, powering in the same way through the
output of the UPS to the load for a limited time, that of the
backup determined by the battery pack.
4.3.2.1.1. Available power ratings.
The SLC ADAPT series has two different power modules, 30
and 50 kVA, as can be seen in Fig. 2, Fig. 4, Fig. 10 and Fig. 12.
4.3.2.2. Static bypass.
Static transfer switch.
In the event of inverter failure, overload or overtemperature,
the voltage connected to the static bypass line can supply
power to the load connected to the UPS output.
The static bypass module identified in Fig. 14 contains the
power management and control circuits that allow the most
optimum decision in each scenario to be made, in order to se-
lect the most favourable power to the critical load connected
to the output of the UPS, either from the inverter or from the
static bypass itself.
During normal system operation, the load is connected to the
inverter and in case of overload or failure, it will automatically
transfer to the static bypass line. In order to provide a clean
transfer (without interruption) between the inverter output and
the bypass line, they must be fully synchronized during normal
operation. This is achieved through real-time digital control of
the inverter, so that the frequency of the inverter follows the
frequency of the bypass line if the bypass is within the range of
acceptable frequencies.
In addition, a Manual Bypass, which is very useful during periods
of maintenance or failure, is included and allows continuous
powering of the critical load while the UPS is out of service.
When the UPS is operating in bypass mode (over static
bypass), connected devices are not protected against
power cuts or micro-cuts, overvoltages, voltage and/or fre-
quency variations as they are powered directly from the AC
mains.
4.3.2.3. Extra charger modules for 180 and 300 kVA devices.
The smart charging module is designed to supply the necessary
charging current for long backup applications. The module is hot
swappable and has the same size and appearance of any power
module, supplying an adjustable current of between 0 and 50 A.
On the front, they have a high resolution LCD where the user
can monitor the different load parameters in real time.
The modules are designed to be inserted in 6- and 10-slot
cabinets with only 30 kVA modules - 180 and 300 kVA devices
- and can be inserted in the necessary number to meet battery
charging needs.
4.3.2.3.1. Wiring diagram.
As can be seen in the diagram in Fig. 15, the charger modules
are connected in parallel to the power modules. The total cur-
rent of the system is the sum of the current supplied by the
power modules and the charger modules.

The modular double-conversion on-line UPS has the following
operating modes:
•Normal mode
•Battery mode
•Bypass mode
•Maintenance mode (manual bypass)
•ECO mode
•Frequency converter mode
During the description of the operating modes the operation
is described referring to the PFC-rectifier and inverter parts as
functional parts of a module, although there will be as many of
them as there are modules connected in parallel.
4.3.3.1. Normal mode.
The inverter of each power module is responsible for powering
the critical loads at all times. The rectifier/charger of the AC
input powers the inverter with DC voltage while simultaneously
charging the associated backup battery, either at float or quick
voltage.

4.3.3.2. Battery mode.
In the event of failure of the AC input power mains, the inverter,
by means of the power it obtains from the battery, supplies the
critical loads of the output in AC. By doing so, the power supply
is not interrupted in the event of failure. Once the AC power
input is restored, the ‘Normal mode’ function will be restored
automatically without the user needing to intervene.

4.3.3.3. Bypass mode.
If the inverter’s overload capacity is exceeded in Normal
mode, or if the inverter cannot supply power to the loads for
any reason, the static switch will transfer the inverter’s load
to bypass, without interrupting the power to the critical loads.
If the inverter is not synchronised with the bypass, the static
switch will transfer the load from the inverter to the bypass,
interrupting the load. This is done to prevent short circuits due
to the paralleling of non-synchronised AC inputs. The time of
this interruption is programmable, the typical value being less
than 3/4 of a cycle, e.g. less than 15 ms (50Hz) and 12.5 ms
(60Hz). The transfer or retransfer action can be performed via
commands through the control panel.

4.3.3.4. Manual Bypass mode (maintenance bypass).
If the UPS requires intervention due to breakdown or main-
tenance (for example, because there is a power module, the
bypass or the LCD with anomalies), there is the possibility of
continuing to supply the loads through the internal manual by-
pass (maintenance bypass).
When the UPS is operating in ‘Manual Bypass Mode’
(maintenance or repair period), the connected equip-
ment is not protected against power cuts or micro-cuts, over-
voltages, voltage and/or frequency variations, etc. when fed
directly from the commercial AC network.

mode (maintenance).
DANGER: During manual bypass mode, the input,
output and bypass terminals (version B) are live even if
all modules are switched off.
It is recommended in this operating mode:
–Remove the fastening screws of all power, control
and bypass modules.
–Slightly pull the handles on each one until they are
protruding by about 4-5 cm from their housing in
order to enable them to be unplugged from their
connector located on the backplane of the device.
Before any change of operating mode and after carrying out the
possible corrective actions, it is necessary to correctly insert
the modules to their original position and fix them with their
screws.
4.3.3.5. Parallel-Redundant mode.
This operating mode allows to obtain a greater capacity, reli-
ability or both, being able to be configured like extension of
power or like redundancy.
As a consideration to be taken into account when the cabinets
are in parallel, the controller included in each one guarantees
the automatic distribution of the load in all of them and all of
its modules.
4.3.3.6. ECO mode.
ECO mode saves energy. In this mode, when the input voltage
of the Bypass is within the ECO voltage range, the static bypass
that supplies power directly to the loads is activated, leaving
the inverter in standby. When the Bypass voltage or frequency
is out of range, the UPS transfers the output to Inverter.
During the transfer of the load on the inverter from ECO
mode, a small interruption (less than 10 ms) occurs. It is
very important to ensure that the critical load powered in this
UPS mode tolerates that interruption time.

4.3.3.7. Frequency converter mode.
When operating in this mode, the device supplies a fixed
output frequency of 50 or 60 Hz, or different input and output.
When operating in this mode, the static bypass is inhibited
and the manual bypass switch should not be operated due to
the consequences it could have on the loads connected to the
output.
