3-phase UPS
High power solution for large,
mission-critical systems
Flexible and smart
The innovation and design of the Fluxpower HPS high
power UPS has resulted in the unit being the most
technologically advanced in its class.
It delivers an incredible combination of low input current
distortion, unity input power factor and high overall efficiency.
These advances in design offer numerous benefits, including
lower running costs and substantially increased reliability.
Low THDi and power factor performance
The Fluxpower HPS model UPS uses a completely new IGBT input
rectifier design, encompassing an advanced PFC (Power Factor
Control) which is capable of keeping input current THDi (Total
Harmonic Distortion) at a level of less than 3 % and input power
factor within 1 % of unity, even when only small loads are applied.
The key benefits are that the UPS is compatible with the
upstream source, the mains or any kind of generator and the
transfer of power between source and load is more efficient.
This results in a saving in terms of scale of sources, cables
and protective devices.
High efficiency reduces overall cost
of ownership
Fluxpower HPS has a new Wise ECO function which enables a
total operating efficiency of between 95 % and 98 %. This mode,
referred to as “Intelligent ECO mode”, significantly reduces
the utility costs associated with operating a device of this type.
Moreover, this increase in efficiency results in the production
of less waste heat, minimizing cooling / air-conditioning costs.
This represents a double saving to the energy conscious user.
The Wise ECO function uses continual monitoring techniques to
review the input characteristics of the supply. This means that if the
supply line drops or fluctuates outside of acceptable conditions the
UPS uses the internal inverter to support the load. This is achieved
through a fast, fully static transition from VFD to VFI mode.
OPTIONAL (External Manual bypass)
1. Input mains (separate for by-pass and rectifier)
2. Rectifier and battery charger
3. External battery
4. Inverter
5. Emergency line (by-pass) with optional backfeed
6. Inverter (SSI) and by-pass (SSB) static switch
It is possible to install an external manual bypass,
either in the matching cubicle or in wall mounted box
(bypass switch auxiliary contact must be connected
to UPS related input port for status monitoring).

“Green” double
protection for every
VFI online double conversion
topology in this equipment
offers built-in inverter galvanic
protection completely isolating
the output power from all
input power anomalies,
delivering fully conditioned
pure sine-wave output.
In pure on-line mode the unit
delivers an excellent certified
96 % efficiency. Because of
the technology and topology
used, no additional losses are
generated to achieve low input
harmonics or input / output
galvanic isolation.
The Fluxpower HPS unit is
designed to provide excellent
output voltages suited to very
demanding applications
with either 100 % step load,
unbalanced, non-linear
or modern IT loads. It also
provides exceptional
performance: with a power
factor of up to 0.9 (lagging
or leading), there is no
requirement to de-rate the unit.
Triple Intelligence
The Fluxpower HPS is
designed to overcome the
limitations imposed by other
older, designs. With its
distributed control architecture,
Fluxpower HPS will always
have a UPS circuit protecting
the load; furthermore,
the status of most critical
components is constantly
monitored, allowing predictive
maintenance and avoiding
unexpected breakdowns.
Fluxpower HPS’ working state
can be easily monitored by
any Building Management
System and via LAN / WAN.
Battery Management
Batteries are electro-chemical
devices, which store charge
chemically; as such their
performance degrades with
time. The Fluxpower HPS owns
a Battery Anti-Aging Control
(BAAC) according to battery
manufacturers’ requirements.
If the application requires
extremely flexible and
reliable UPS protection,
the Fluxpower HPS is ideal.
It delivers advanced features
based on state-of-the-art total
digital control. This control
incorporates dual DSP (Digital
Signal Processing) and µC
(Micro controller) technologies.
Following a UI characteristic
curve, the charger charges at
a constant current appropriate
for the battery type used,
preventing detrimental
excess charging. In addition
to the float voltage level,
boost charge can be set,
optimizing the recharge time
when there is the possibility
of consecutive power outages
within a short period.
The system design ensures that
auxiliary power supplies and
processors are no longer single
points of failure which could
compromise the availability
of clean power to the load.
BAAC also reduces the
residual ripple current (one
of the causes of premature
battery wear), as well as
protecting the battery from
damaging deep discharges.
Automatic battery temperature
compensation charge voltage
may be implemented,
charging the battery more
appropriately and increasing
battery life. By means of DCM
(Dynamic Charging Mode)
very long battery autonomies
can be achieved without
increasing total charge time.
This is achieved through
the implementation of an
intelligent increase in maximum
battery charge current when
the maximum inverter power is
not being drawn by the load.
An integrated periodical
battery testing function tests
and monitors battery health,
providing advanced warning
to guide the application of
preventive maintenance.
Parallel systems
with “hot swap”
Fluxpower HPS UPS offers
parallel options in both
redundancy and capacity
modes, providing the
possibility for both extra
system resilience and
increased capacity.
The parallel control circuitry
associated with these units
is fully digital and acts on
both active and reactive
power on each of the three
output phases. This allows
accurate load current sharing
among the UPS units even
during transient conditions.
Easy installation,
operation and
Parallel control is distributed
between all units and
communication is achieved
through the use of a CAN bus
connection loop. This has
the effect of producing a
highly reliable system with
“no single points of failure”.
Intelligent design of the
system connections allow
for easy installation and
easy future upgrades, this
allows for upgrading in the
field without difficulty.
In modular arrangement,
units can be added or
removed “hot” without
load disturbances or the
need to switch to bypass.
Smart Parallel functions
facilitate the automatic
switching off of units where
the total power requirements
of the load is provided by
fewer than the total number
of UPS units attached.
This is commonly known as
“load based shutdown”
and maximizes the efficiency
of the complete system by
keeping the load on each
module at an optimum level.
Two independent paralleled
systems can be synchronized
(Sync Control) in order to
feed downstream STS’ for
seamless transfers.
Fluxpower HPS can easily be
sited within areas no wider than
1200 mm, and can be installed
close to walls or other cabinets
as cooling air is expelled
through vents on the top of the
unit. This new design also gives
the user significant savings in
floor utilization and is an ideal
solution where space is at a
Despite the modern, compact
design, all critical components,
are accessible from the front
of the unit; this improves
accessibility to allow regular
maintenance and reduced
Mean Time to Repair (MTTR).
Fluxpower HPS also
incorporates a unique
back-feed power protection
system. If the output of the
UPS is fed back into the mains,
the unit will immediately
isolate itself. This removes
the need for additional MCBs
or other similar safety devices.
