Suggestions
to rate an UPS
The
power of an UPS is measured in VA or W.
In
order to correctly rate an UPS it is necessary to know which equipment
will be connected.
It is moreover necessary to purchase an UPS slightly more powerful
than necessary, because pc power absorption is not homogeneous,
and because you may need to connect other loads in the future.
This
table presents the absorption of some commonly used devices.
To
have a more precise calculation, or to rate UPS with high voltages,
