Why an Uninterruptible Power Supply?
Data centres, servers, LAN nodes and telecommunication systems
must always be protected against possible problems in the power
supply. Sudden blackouts and variations in the mains supply may lead
to system malfunctions and severe data losses. But even other
electrical equipment can cause damage or inconvenience if there is a
breakdown in the mains. Just think of the check-out systems in a
supermarket, lighting systems and industrial production units, not to
mention safety systems, pumping systems and automatic devices in
general.
The simplest and most effective way of coping with these
disturbances is to install a UPS unit (UPS stands for Uninterruptible
Power Supply). Acting as an interface between the mains and the
loads, the UPS guarantees the continuity and the quality of the
electrical power supplied to the loads, whatever the condition of the
mains may be. In fact these systems stabilise the voltage perfectly,
eliminating all disturbances.
They even supply voltage when the mains fails, by means of a series
of batteries which give a back up time that is generally sufficient to
guarantee the safety of persons and of the system.
In order to decide which type of appliance is able to guarantee the
best level of protection, you must know the types of mains problems
that can disturb your systems.
Power problems are caused
by various sources such as
distribution network faults,
system switching, weather
and environmental
conditions, heavy equipment
or simply just faulty
maintenance.
