The appropriate Uninterruptible Power Supply – UPS is vital for the safety of your work and systems.
Be careful, however, not to make a closed-box purchase.

In order to make purchases without ‘nasty surprises’, we suggest you follow the following points:

• Define the actual technology of the UPS: stand-by, line-interactive, on-line double conversion.
• Compare the power of UPSs in the unit of active electrical power, i.e. the Watt.
• Ask specifically about the autonomy at full load.
• Check quality certifications.

This way you will have unambiguous comparison parameters and avoid ‘buying potatoes at the price of truffles‘.
