OVERVIEW
Sirius
The UPS in the Sirius 10 – 12 – 15 – 20 kVA series (VFI-SS-111 type) was designed using state-of-the-art
technology so as to ensure the best performance for the user. The use of the new control boards based on
multiprocessor architecture (DSL +  P inside) together with high-frequency IGBT technology ensures extraordinary
performance from both the input stage (absorbed current harmonic distortion ≤3%) and the output stage (output voltage
distortion ≤1%).
Due to its modern, innovative design, large graphic display and, above all, greater power provided by the battery charger
(up to 6A recharge), the Sirius series represents a new reference point in the world of three-phase UPS.

THE BATTERY BOX IS AN OPTIONAL ACCESSORY PROVIDED FOR THIS RANGE OF UPS (SAME SIZE AND
AESTHETIC DESIGN).
The Battery Box contains batteries that increase the operating time of the UPS during prolonged black-outs. The number
of batteries contained in it will vary according to the type of UPS to which the Battery Box is to be installed. The utmost
attention must be paid to ensure that the battery voltage of the Battery Box corresponds to that supported by the UPS.
Additional Battery Boxes may be connected in a chain to obtain the desired autonomy time during a power failure.
This series of Battery Box contains two separate strings of batteries, one with a positive voltage and the other with a
negative voltage with respect to the neutral terminal (N).
The basic diagram for the Battery Box is shown here below.
