Specifications
Sentinel 5 Plus
Absolute protection
Sentinel 5 Plus 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 true sinusoidal voltage
that is free from electrical interference.
High immunity to lightning
A device providing protection from
input and output overvoltages means
that Sentinel 5 Plus is able to withstand
input overvoltages of up to 6kV, in
accordance with IEC 801-5, thus
ensuring the maximum protection to the
powered load.
Total microprocessor control
Digital control of the appliance
considerably improves system reliability,
reduces unit dimensions and weight,
and significantly increases control and
communications capabilities.
Battery optimization
The UPS periodically performs a battery
efficiency test. The batteries are not
actuated during microinterruptions (40
ms), which are the most common type
of mains interference, since the
required energy is drawn from a group
of capacitors. This system (battery
saving) extends the life of the batteries.
A similar feature is provided by the
Active Control (LRCD) of the battery
current even during the discharge
phase, which means that the
alternating components on the battery
can be eliminated.The Sentinel 5 Plus
range also comes with a device to
protect against deep discharges, which
can affect the expected battery life.
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, etc., 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 also contains the following
hardware interfaces:
• RS232 serial port,
• Dry contacts,
• EPO (Emergency Power Off) contact
for UPS shutdown from the remote
emergency button.
The UPS comes with an expansion slot
for optional communication boards
such as Netman and MultiCom.
