4.3. OPERATING PRINCIPLE.
This user manual describes the installation and mode of operation
of SPS.ADVANCE RT2
800 and 3000 VA.
These line-interactive pure sine-wave output devices are designed
to protect your most sensitive electronic devices against power
supply problems including undervoltages, spikes, prolonged
voltage drops, line noise and mains failures.
SPS.ADVANCE RT2
AC power at their output through the IEC sockets installed on the
back of the device. If mains supply is correct, the load or loads
are powered from it through the stabiliser featuring buck-boost
technology.
If mains supply is absent or the voltage and/or frequency are out of
the acceptable range, the load or loads will be powered from the
batteries through the inverter for a certain period of time depending
on the model, battery charge level and load itself connected to the
output.
In all of the models, it is possible to increase the standard backup
of the devices by connecting additional modules and/or optimising
the recharge time of the accumulators by incorporating higher
performance chargers (B1).
The entire range of power ratings enables:
The serial and USB ports for communication and control of
•
the device. The serial port supports communications directly
with a server and the protocol is in accordance with an RS232
interface, which also has dry-contact signals (interface to
optocouplers).
RJ-45 connectors for protecting the modem / ADSL / fax line.
•
An EPO connector for optional, external installation by the user
•
of an emergency stop button.
A smart slot in which one of the following communication
•
cards can be installed:
Integration into computer networks using an SNMP
ˆ
adapter.
Modbus RS485.
ˆ
Interface to relays.

This manual applies to the standardised models shown in .
4.3.1. Notable features.
Pure sine-wave output waveform, suitable for almost all types
•
of load.
Possibility of starting the device without mains power supply
•
or discharged battery (cold start). Be careful with this aspect
because the greater the batteries are discharged, the more the
backup will be reduced.
Great adaptability to the worst conditions of the mains. Wide
•
input voltage, frequency and waveform ranges, thus avoiding
excessive dependence on limited battery power.
If mains supply is present and voltage and frequency are
•
within the range, the built-in stabiliser featuring buck-boost
technology powers the loads.
44
series UPSs for the power range between
devices are powered by the mains and supply
Possibility of fast and easy backup extension by adding battery
•
modules.
Availability of additional battery chargers to reduce battery
•
recharge time (B1).
Intelligent battery management technology is very useful for
•
extending the life of accumulators and optimising recharge times.
Control panel with LCD display available on all models.
•
Remote emergency power off control (EPO).
•
Serial communication port: RS232 and USB.
•
Availability of optional connectability cards to improve
•
communication capabilities.
Protection against overload, short circuit and overtemperature.
•
Device that can be installed as a tower or rack using the ac-
•
cessories supplied. The control panel can be rotated to adapt
to either format.

4.4. OPTIONAL EXTRAS.
Depending on the configuration chosen, the device may include
any of the following options:
4.4.1. Isolation transformer:
The isolation transformer provides galvanic isolation in order to
completely isolate the output from the input and/or change neutral
mode.
The placement of an electrostatic screen between the primary
and secondary windings of the transformer provides a high level of
electrical noise attenuation.
The isolation transformer can be physically placed at the input
or output of the UPS depending on the technical conditions of
the whole system (device supply voltage and/or load voltage,
characteristics or their type, etc.).
In any event, it will always be supplied as a peripheral component
external to the device itself in a separate box.
Type Input/output type
Single-phase / Single-phase.
