Operating Principle - Salicru SPS 750 ADV R User Manual

Note related to B1 batteries:
(b1) device with a more powerful charger, which does
not have a battery pack, nor the possibility of in-
stalling them in the same box.
If an accumulator module is required, it will need
to be ordered as a separate item, which will be
connected to the UPS using the supplied cable.
before connecting a module or group of batteries to the
device or another available module,
to check that the voltage value printed on the back of
the device next to the battery connector is appropriate
and that the polarity between the means of connection
corresponds.
for more information, see Chapter 9 of this document.

4.3. operaTing prinCiple.

This user manual describes the installation and mode of opera-
tion of SPS AdvAnCe R and SPS AdvAnCe T series UPSs indi-
cated in Tab. 1 and Tab. 2.
These line-interactive pure sine-wave output devices are de-
signed to protect your most sensitive electronic devices against
power supply problems including undervoltages, spikes, pro-
longed voltage drops, line noise and mains failures.
with the device running and the mains supply correct, the load
or loads are powered through the stabiliser featuring buck-
boost technology. Any possible variations in the input voltage
are corrected by the stabiliser module while they are within its
regulation range.
with mains supply absent or voltage and/or frequency outside
the 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.
when plugged into an AC socket, the batteries are set to charge
mode regardless of whether the device is on or off.
In SPS AdvAnCe T 1000 to 3000 vA models, it is possible to
increase the standard backup of the devices by connecting ad-
ditional modules and/or optimising the recharge time of the ac-
cumulators by incorporating higher performance chargers (b1).
The entire power range of SPS AdvAnCe R and T models ena-
bles:
Serial port 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.
SPS AdvAnCe T models also have an additional USb serial
port for communication and control of the device. It is not
possible to use the RS232 and USb ports at the same time.
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.

Compatibility with APfC loads.
•
The vast majority of power supplies for electronic devices
are switched-mode (SmPS) and they are increasingly being
equipped with active power factor correction (APfC) to
minimise distortion caused to the electrical line. SPS home
UPSs are compatible with all devices that incorporate these
functionalities.
