ESCRIPTION
The purpose of a UPS is to ensure a perfect power supply voltage for the devices connected to it irrespective of whether
mains power is present or not. Once connected and powered, the UPS generates a sinusoidal alternating voltage with a
stable amplitude and frequency, irrespective of the changes and/or variations occurring on the electricity network. For as
long as the UPS receives energy from the mains, the batteries are kept charged under the control of the multiprocessor
board. This board also controls 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 efficiency
of the batteries.
The block diagram below shows each of the parts that make up the UPS.
IMPORTANT: Our UPS are designed and produced for long life even under the severest conditions. Remember however
that they are electrical power equipment items and as such are in need of periodic checks. Besides, some components
have a life cycle of their own and must therefore be checked at regular intervals and may need to be replaced, where
due to the conditions: in particular, the batteries, fans and in some cases the electrolytic capacitors.
It is recommended to implement a preventive maintenance program, using manufacturer authorised and trained service
personnel.
Our Technical Servicing department is at your disposal to discuss the different personalized preventive maintenance
options with you.
