Vega stabilisers are available for different ranges of input voltage fluctuation.
Standard models offer a double input connection so that with the same unit two different input variations (±15/±20% or ±25/±30%) can be dealt with.
An automatic circuit breaker is mounted on the regulation circuit to protect against overload and short circuit on the voltage regulator, whilst the auxiliary circuit is protected by fuses.
A digital display on the front panel shows the output voltage and the alarms (min/max output voltage,
gearmotor lock, internal overheating, regulator overload)
The control logic is based on a digital microprocessor.
All Vega stabilisers are fitted with the same control card, thus simplifying maintenance operations and
spare parts storage.

Antares stabilisers are available for different ranges of input voltage fluctuation.
Standard models offer a double input connection so that with the same unit two different input
variations (±1 5%/±20% or ±25%/±30%) can be dealt with.
An automatic circuit breaker is provided on the regulation circuit to protect against overload and short
circuit on the voltage regulator whilst the auxiliary circuit is protected by fuses.
The instrumentation consists of a digital multimetre installed on the cabinet front panel. The alarms (min/max output voltage, gearmotor lock, internal overheating, regulator overload) are recognizable by
means of LEDs on the control card.
The control logic is based on a digital microprocessor.
All Antares stabilisers are fitted with the same control card, thus simplifying maintenance operations and spare parts storage.

Orion stabilisers are available for different ranges of input voltage fluctuation.
Standard models offer a double input connection so that with the same unit two different input
variations (±1 5%/±20% or ±25%/±30%) can be dealt with.
The output voltage regulation is performed independently on each phase (stabilization of each phaseto-
neutral voltage).
Orion stabilisers are used with three-phase loads and single-phase loads with 100% current imbalance across the phases and asymmetrical mains voltage.
For the correct operation, Orion voltage stabilisers require the neutral wire presence. Operation without
neutral wire connection is achievable by adding a device able to generate it (D/Yn isolating transformer
or neutral point reactor).

Orion Plus stabilisers are available for different ranges of input voltage fluctuation. In the ±15%/ ±20%
and ±25%/ ±30% types, the change of input range is obtained through different internal connections.
The Orion Plus voltage stabilisers regulate the output voltage independently on each phase.
Similarly to the Orion stabilisers, they can supply any single-phase, bi-phase and three-phase load
even in case of and up to 100% unbalanced load current and asymmetrical mains distribution.
In this configuration, the presence of the neutral wire is required. The stabiliser can also operate
without neutral wire by adding a device able to generate it (D/zn or D /yn isolating transformer or neutral
point reactor).

Sirius stabilisers are available for different ranges of input voltage fluctuation. In the ±15%/ ±20% and
±25%/ ±30% types, the change of input range is obtained through different internal connections (only up
to 2000kVA ±15% and equivalent).
Sirius stabilisers are equipped with columnar voltage regulators which enable the achievement of high
ratings (up to 6000kVA) and a solid and reliable construction, thus meeting the most diverse industrial applications.
The Sirius voltage stabilisers regulate the output voltage independently on each phase. Similarly to the
other models, they can supply any single-phase, bi-phase and three-phase load even in case of and up
to 100% unbalanced load current and asymmetrical mains distribution.

Sirius Advance voltage stabilisers derive from the SIRIUS type, of which they maintain the main technical characteristics.
The standard integration of some functions and accessories usually offered as optional, complete and enrich the equipment.
The additional features are:
– Input automatic circuit breaker;
– Bypass switch via an interlocked automatic circuit breaker;
– Output interlocked motorized automatic circuit breaker;
– Integrated automatic power factor correction system.

OPTInet has been specifically designed to meet the ever increasing power quality issues that can be
easily found in a wide range of industrial applications.
OPTInet combines the established and consolidated characteristics proper of voltage stabilisers with features that enable the achievement of energy saving and power quality improvement.
One of the factors that most affect energy saving is given by the fact that electrical appliances are usually designed to operate with an input voltage included in range rather than just one nominal voltage.
Nevertheless, supplying a device a voltage higher than the rated one implies higher consumption and
decrease of the expected life.
