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 effi ciency.
These advances in design offer numerous benefi ts, 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
rectifi er 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 benefi ts 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 effi cient.
This results in a saving in terms of scale of sources, cables
and protective devices.

High effi ciency reduces overall cost
of ownership

Fluxpower HPS has a new Wise ECO function which enables a
total operating effi ciency of between 95% and 98%. This mode,
referred to as “Intelligent ECO mode”, signifi cantly reduces
the utility costs associated with operating a device of this type.
Moreover, this increase in effi ciency 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 fl uctuates 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.

“Green” double
protection for every
application

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

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.

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.

3xL-N3xL

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.

Life-prolonging
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.

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.

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.

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).

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”
modularity

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.
