Riello PCI India Pvt Ltd has
introduced Multisentry UPS
system to enable business-criticalcontinuity
in India's industrial houses.
This model is introduced in order to keep
pace with ever increasing demand for
uninterrupted quality power supply.
The "Multi Sentry" series is ideal for
protecting data centre and
telecommunications systems, IT
networks and critical systems where poor
power quality can lead to a loss of
operations and service.
The series is available in 10-12, 15-20
kVA models with three-phase and singlephase
input and single-phase output, and
10-12-15- 20-30-40-60-80- 100-120
kVA models with three-phase input and
output with On-line double conversion
technology, according to the VFI-SS-111
classification, as defined in IEC EN
62040-3, Multisentry offers all features
of an enterprise/industrial UPS. Highly
flexible design allows full compatibility
both with three-phase and single-phase
power supplies.
Multi Sentry has zero impact on its
power source, being either the mains
power supply or a generator.
It reduces the Input current
distortion to less than 3 per
cent and the input power
factor becomes 0.99. In
addition, Multi Sentry plays
a filter and power factor
correction role in the power
network upstream of the
UPS, as it eliminates
harmonic components and
the reactive power, generated
by the powered utilities.
Multisentry is the best
solution for those looking for
eco-sustainable options as it
allows for a saving of more
than 50 per cent of the energy
dissipated in a year, compared to similar
product in the market. Thanks to its stateof-
the-art technology, three levels NPC
inverters have been designed which
ensures a high output of 96.5 per cent. The
exceptional performance makes it
possible to recover the initial investment
cost in less than three years of operation.
Proper battery care is critical to
ensuring the correct operation of UPS in
emergency conditions. Multi Sentry
allows for battery management in order to
obtain the best performance
possible and extend their
operating life. Ripple current
is one of the most important
causes of a reduction in
reliability and battery life.
Thanks to a high frequency
battery charger, Multi Sentry
reduces this value to
negligible levels, prolonging
battery life and maintaining
high performance over a long
period of time.
The system gives maximum
reliability and availability
connected upto 6 units in
Redundant (N+1) or parallel
configuration. The UPS
continues to operate in parallel even in
the event of an interruption in the
connection cable. With an Output power
factor of 0.9, that provides up to 15%
more active power than a standard UPS
on the market, Multisentry guarantees a
greater margin in UPS sizing for
potential load increase.
The configuration flexibility,
accessories and options and performance
makes Multisentry suitable for wide range
of industry applications.
