3.3. Operating principle.
This manual describes the installation and operating of the Un-
interruptible Power Supply (UPS) from
SLC TWIN PRO
series
as equipments that can operate separately or connected in
parallel, without needing a centralised bypass. UPSs from
SLC
TWIN PRO
series assure an optimal protection of any critical
load, keeping the power supply voltage to the loads between the
stated parameters, with no break, during a blackout, deterioration
or perturbations of electrical commercial mains and with a wide
range of available models (from 4 to 20kVA), it allows adapting
the model to the end-user needs.
Thanks to the used technology, PWM (pulse width modulation)
and double conversion, UPS from
SLC TWIN PRO
series are
compact, cold, silent and high efficiency.
The double conversion principle cancels any perturbations from
mains energy. A rectifier converts the AC alternating current from
input mains into DC direct current, keeping an optimal battery
charging level and supplying the inverter, and at the same time
creates an AC sinewave voltage ready to feed the loads perma-
nently. In case of UPS input mains fault, the batteries supplies
clean energy to the inverter.
The UPS design and construction from
SLC TWIN PRO
series
has been done in accordance with the international regulations.
These equipments allow the upgrading by means of the connec-
tion of additional modules of the same power rate, to get redun-
dancy (i.e.: N+1) or to increase the capacity of the system.
So, this series has been designed to maximize the availability of
the critical loads and to assure that your business is protected
against perturbations of voltage, frequency, electrical noises,
blackouts and mains faults, which are present in the energy
distribution lines. This is the main target of the UPSs from
SLC
TWIN PRO
series.
This manual can be applied to the standardised and stated
models in table 1.
3.3.1. Main features.
•
True on-line double conversion and independent output fre-
quency from mains.
•
Output power factor of 0,9 and pure sinewave, suitable for
almost any kind of loads.
•
Input power factor > 0,99 and high general efficiency (> 0,92
for single phase input or > 0,93 for three phase). High en-
ergy saving and low cost for the user's installation (wiring)
is achieved, as well as low input current distortion, so mains
pollution is decreased.
•
Great adaptability to the worst conditions of the input mains.
Wide margins of the input voltage, frequency range and
wave shape, so it is avoided the excessive dependence on
the limited energy of the battery.
•
Availability of battery chargers up to 12A in order to decrease
the battery recharging time.
•
Parallel redundant connection N+X to increase the reliability
and flexibility. 4 equipments in parallel as maximum.
•
High efficiency mode can be selected > 0,97 (ECO-MODE).
Energy saving, which reverts to the user in an economy way.
•
It is possible to start up the equipment without mains or the bat-
tery discharged. Watch this last aspect, because the back up
time will be decreased as much discharged the batteries are.
•
The technology of the smart management of the battery is
very useful for making longer the accumulator lifetime and to
optimise the recharging time.
•
Standard communications options by means of RS-232 or
USB ports.
•
Control of the remote emergency power off (EPO).
•
Control signal of the remote emergency power off (EPO).
•
Interface between the user and the equipment through the
control panel and LCD with led indicators, user friendly.
•
Option cards are available to improve the communication ca-
pacity of connectivity.
•
Easy firmware updating, no need to call to the Service and
Technical Support (
S.T.S.
).
•
Simplified maintenance, which allows replacing the batteries
in a safety way without shutdown the UPS.
