ESCRIPTION
The purpose of this UPS is to ensure a perfect power supply voltage for the devices connected to it, whether mains power is
present, or not. Once it has been connected and powered, the UPS generates a sinusoidal alternating voltage with stable
amplitude and frequency, regardless of any sudden change or variation in the mains supply. While the UPS draws energy from
the mains, the batteries are kept under charge, controlled by the multiprocessor board. This board also monitors continuously
the amplitude and frequency of the mains voltage, the amplitude and frequency of the voltage generated by the inverter, the
load applied, the internal temperature and the state of battery efficiency.
The UPS block diagram is shown below with a description of its individual components.

IMPORTANT:
Our UPSs are designed and built for long durability, even under the most stringent operating conditions.
However, it is important to remember that they are electrical power equipments and therefore, need regular checks. Moreover,
some components inevitably have a life cycle of their own, so, for this reason, they need to be checked regularly and, if
necessary, be replaced. This is referred in particular to the batteries, the fans and, in some cases, to the electrolytic
condensers.
Therefore, a preventive maintenance programme is strongly recommended. This preventive maintenance programme must be
entrusted to specialised personnel authorised by the manufacturer.
Our Technical Servicing department is at your disposal for customised preventive maintenance options.
