Flexus
Flexus is ideal for the protection of critical
information and telecommunications
networks which cannot run the risk of
being powered from a power quality
electrical supply.
The Flexus series is available in 10-12-
15-20 kVA three-phase or single-phase
input and single-phase output models,
and 10-12-15-20-30-40-100-120 kVA
three-phase input and output models,
with double conversion on-line
technology according to the VFI-SS-111
classification, as defined by the IEC EN
62040-3 standard.
Flexus has been designed and
manufactured using state-of-the-art
technologies in order to deliver maximum
protection for critical users, a zero
impact on the mains power supply and a
high operating efficiency.
The high level of flexibility at the design
stage means that there is full
compatibility both with three-phase
power and with single-phase sources,
thus eliminating any critical factors in the
connection between UPS and system.
ZERO IMPACT SOURCE
The superior technology of a Flexus UPS
allows it be used where the site mains
power supply is limited in capacity, or
has an on-site generator and/or loads
that generate current harmonic problems.
Flexus is designed to have a zero-impact
on its upstream power supply (mains or
generator):
• Input current distortion < 3%
• Input power factor 0.99
• Power walk-in function to guarantee a
progressive rectifier start-up
• Delayed switch-on function, to
sequentially restart the UPS when
installed as part of a parallel system.
Flexus also act as a filter and phase-shift
protection device in respect to its
upstream supply, providing protection
from any harmonic components or
reactive power generated by
downstream loads.
BATTERY CARE SYSTEM
Battery management is one of the
fundamentals of UPS management in
order to ensure the system can perform
in emergencies. The Flexus Battery Care
System consists of a number of
functions that together guarantee
optimum battery performance.
Battery recharge: Flexus is suitable for
use with sealed Valve Regulated (VRLA),
AGM, GEL and open-vented lead acid
batteries, in addition to Nickel-Cadmium.
Depending on the battery type used, the
recharging functions can include:
• One-level recharge, typical for the most
commonly used VRLA AGM batteries
• Two voltage level recharge according
the IU characteristic
• Charge blocking system to reduce
consumption of the electrolyte and
further extend the life of VRLA
batteries.
