Riello UPS reveals new Sentinel
Tower range
R
iello UPS, an award-winning
manufacturer of uninterruptible
power supplies (UPS) and standby
power systems, has introduced a new
product delivering high performance and
efficiency in a compact footprint.
Available in a 5–10 kVA power
range, the Sentinel Tower (STW) is
designed to protect mission-critical
telecommunications and IT networks,
along with security and lighting systems.
Manufactured using the most advanced
double conversion online UPS technology,
the STW delivers unity power factor and
incorporates a three-level inverter that
enables operating efficiency of up to 95%,
minimising wasted energy.
Up to three Sentinel Towers can work
together in parallel to offer redundancy
and the flexibility to easily upscale when
load requirements change. The UPS
operates on a closed loop system which
ensures it continues to run even if the
cable connection is interrupted. The 5–6
kVA versions are single-phase input and
output power supplies, while the 8–10 kVA
models are single or three-phase input and
single-phase output.
Riello UPS General Manager Leo Craig
said: “Combining exceptional reliability
and efficiency in such a compact
footprint, the Sentinel Tower is a versatile
choice suitable for sectors as diverse as
healthcare, finance and public transport.
“It comes with a whole host of user-
friendly features, including a completely
redesigned LCD display panel, built-in
wheels for portability and a wide range of
sophisticated operating modes to improve
performance and boost efficiency.”
Featuring automatic and manual battery
testing functionality, the STW range also
includes extended run-time versions
equipped with 6A chargers for
critical applications requiring several
hours’ autonomy.
The introduction of the STW series is
the latest of several recent product and
service enhancements from Riello UPS.
As well as upgrading both its best-selling
Sentinel Dual (SDU) and NextEnergy (NXE)
ranges with several new models, it also
developed the Sentinel Rack (SER), a new
rack-mounted version of its popular single-
phase Sentinel Pro.
In addition, the power protection specialist
unveiled a ground-breaking five-year
warranty as standard on all UPS systems
up to and including 3 kVA.
This extended warranty applies to
customers based in the UK and Ireland
purchasing direct from Riello UPS or an
approved reseller only. ◊
