INTRODUCTION
What is a UPS?
A UPS, acronym of Uninterruptible Power Supply, is an equipment that provides emergency power when
the utility mains fails. It is equipped with batteries that start to work when a power outage occurs.
the utility mains fails. It is equipped with batteries that start to work when a power outage occurs.
It also regulates the electric flux, reducing or increasing the different electric fluctuations and
eliminating the bad harmonics of the means. It is an appropriate protection against power overvoltages,
surges, spikes or brownouts.
surges, spikes or brownouts.
These equipments are typically used to protect computers, networks, communication devices and any
other electric device where an unexpected power surge or disruption could cause data loss or even very
serious damages.
serious damages.
What UPS capacity is the most suitable for me?
The Volt-ampere (VA) is the unit to measure the UPS capacity. It is also called “apparent power”.
However, in this catalogue you will also find the capacity measured in Watts (W), which is the real power,

What is an AVR?
An AVR, acronym of Automatic Voltage Regulator, is an equipment designed to maintain a constant
output voltage level, avoiding the typical voltage fluctuation of the utility mains. It regulates the electric
output voltage level, avoiding the typical voltage fluctuation of the utility mains. It regulates the electric
flux, reducing or increasing the different electric fluctuations of the means, protecting the connected
loads from power overvoltages, surges, spikes or brownouts, increasing their lifespan.

Unlike UPS, AVR are not equipped with batteries, so the connected loads stop working in case of power
failure.
