The centralised bypass is an alternative
to the distributed bypass. Technically the
two solutions fulfil the same purpose, i.e.
to guarantee power continuity, but have
different architectures.
Whilst it is true that distributed bypass
solutions are the most common due to their
flexibility of use and low initial cost, it is
also true that in the medium/large data
centre market centralised bypass solutions
are preferable in terms of technical
performance, footprint and sometimes cost,
above all in large installations where the
number and type of protections as well as
system wiring have an impact.
The data centre and data-storage market
in general is destined for large growth. It
is therefore important to respond to the

various requirements with flexible solutions
that are able to adapt to the growing
demands of the market in terms of the levels
of power and performance required.

Flexibility
The Riello UPS centralised bypass (named
MSB) is available in four standard power
ratings: 800, 1200, 2000 and 3000 kVA .
Intermediate solutions within this range can
be made, as well as solutions greater than
3000 kVA based on the requirements of the
customer or application.
The MSB centralised bypass can be
integrated with the Master HP range; in
fact it can be associated with up to 7 UPS
modules in the range, obviously without
static bypass and associated bypass line
