 OVERVIEW

MULTI SENTRY
The UPS units of the Multi Sentry 10 – 12 – 15 – 20 kVA range (VFI-SS-111 type) have been designed using the latest
technology available today so as to guarantee users maximum performance. The use of the new control PCBs based on
multiprocessor architecture (DSP + P inside) together with high frequency IGBT technology offers excellent performance both
in the input stage (absorbed current harmonic distortion ≤ 3%) and in output (output voltage distortion ≤ 1%).
Thanks to these and many other features plus the easy-to-use design, the Multi Sentry represents a new reference standard in
the three-phase UPS sector.

Depending on user requirements, there are two different versions available:

MCT MST
The Multi Sentry MCT version stands out by its The Multi Sentry MST version, offers longer
compact size and new, modern design. These autonomy than the MCT version, thanks to the
features make it suitable for any environment. possibility to double the number of batteries inside the

BATTERY BOX (OPTIONAL)
THE BATTERY BOX IS AN OPTIONAL ACCESSORY.

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.
