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.
In any case, the presence of the neutral wire is required. The stabiliser can also operate without neutral wire by adding a device able to generate itSee Catalogue
