Sentinel XR
Absolute protection
Sentinel XR is a range of UPSs with
ON-LINE double conversion technology
and with zero transfer time. The load is
always powered by the inverter, which
supplies a true sinusoidal voltage and
current free from electrical interference.
Maximum versatility
Sentinel XR can either be placed on
the floor or inserted in a 19” Rack. The
UPS can be converted from the Tower
version to the Rack version
simply by rotating the control panel to
90° and applying the handles.
Easy battery replacement
The batteries can be replaced while the
UPS is working off the Inverter (hot
swap replacement) without any
disturbances to the load.
Stand-by
When the UPS is not used, it can be
set to stand-by mode. The inverter will
be switched off and the battery is kept
charged. This operating mode is
suitable for Emergency Escape Lighting
(CPSS- Central Power Supply System)
as per standard EN 50171.
Communication slot
Sentinel XR is provided with an
expansion slot for optional
communication cards that enable the
UPS to dialog using the main
communication standards such as:
second RS232 port, serial port
duplexer, Ethernet network agent with
TCP/IP, HTTP and SNMP protocol,
RS232 + RS485 port with JBUS /
MODBUS protocol, signalling relay
card.
Advanced communication
The Aros Watch & Save software
ensures effective and intuitive
management of the UPS. Important
information such as the input and
output voltage, the load applied, the
remaining back-up time, is displayed in
the form of bar graphs. The software is
able to provide information even in the
event of a failure, and can also
programme the UPS for automatic
weekly start-up and shutdown.

The UPS comes with an
expansion slot for optional
communication boards
such as Netman and
MultiCom.
