distortion (THDi <3%) and performance in excess of 96% in On-line
Mode and 99% in Eco Mode. They also boast parallel growth capacity
or unlimited redundant security.

Across the entire range, the batteries are included in the same
cabinet, meaning the floor area occupied is reduced by up to 40%.
They are compatible with all types of battery (including lithium-ion)
and incorporate the Batt-Watch battery care system to maximise
battery life and availability.

Three-level topology with DSP control

Three-level switching, which is based on switching the IGBTs in
half-cycles (positive and negative), controlled by floating point DSP
with exclusive cores for the rectifier and inverter, provides maximum
performance in double conversion.

Lowers cooling costs and increases energy efficiency by more than
96% from a 25% charge, thereby improving TCO by reducing OpEx.

VFI double conversion technology

Double conversion of the voltage between input and output (AC/DC
– DC/AC) in accordance with VFI-SS-111 (EN-IEC 62040-3) operation,
providing clean, stable and reliable voltage at output.

Supplies loads with voltage of the highest quality, protecting them from
any and all disturbances in the mains electricity.

Operation in Eco Mode

When maximising the facility’s performance is the leading priority, Eco
Mode allows loads to be supplied directly from the static bypass, provided
the static bypass is within acceptable voltage and frequency ranges.

Increases the overall performance of the system by up to 99%, thereby
improving the facility’s OpEx.

The UPS is capable of supplying full rated power in the form of kW.

For modern loads with power factor correction, such as servers, it is
not necessary to apply a UPS overdimension factor, resulting in lower
TCO (total cost of ownership).

Silicon carbide devices

Silicon carbide (SiC) devices are the latest development with regard
to performance and efficiency.

They enable systems to operate in a much wider range of temperatures
and at much higher switching speeds, without affecting performance.

Redundant power supply

Modular design

Power modules with a repeating design, divided by phase and
internally arranged in parallel in order to increase power.

The design optimises manufacturing processes and reliability while
reducing the time required for intervention in the event of an incident
(MTTR – mean time to repair).

Security with double bypass

Redundant power supplies for control and the static bypass switch

Ensure the continuity of power even in the event of failure of the
device itself, providing maximum availability.

Unlimited

Offers the capacity to arrange devices in parallel, in order to
ensure maximum availability (redundancy N+1, ..., N+M) as well as
increasing power (increased load demand). Provides the same output
performance in parallel systems as in standalone devices. Continuity
of operation even if the communication signal is lost (depending on
the model).

The availability of the protection is assured by both the redundancy
and the requirements regarding growth in demand.

Double bypass circuit as standard for all models. The static bypass
deals with unforeseen overloads or anomalous situations affecting
the operation of the equipment. There is also a maintenance bypass,
which enables the equipment to be worked on without causing the
loads to be disconnected.

Continuity of load supply under any circumstances.
