We receive numerous requests regarding UPS Protection, but more specifically what extent of the protection is offered by the different types of UPS systems.
As you can see, an online double conversion UPS offers the best protection, from voltage disturbances, for that reason, we will only specify an online type UPS for a building, when the supply power to the building is of a poor quality or if there is a generator installed, however it is still recommended to test the supply quality prior to specifying a UPS system.
BUYING A UPS SYSTEM?
Consumers make fundamental errors when
specifying UPS systems, which often result in costly long term consequences. Incorrect selection of a UPS can seriously impact on the daily running of your business, and as we are all too well aware, in this economic climate every cent counts…
RULES:
1 . Use a UPS and not an inverter for sensitive load, as an inverter
offers very little protection
2 . Check the name plates to establish the power rating for the
equipment on which the UPS is to be installed, as a rule of thumb a
standard PC is about 350Va, but don’t guess, it could be costly.
3 . Amps X Volts = Watts, Watts ÷ PF = VA
4 . If you are installing a UPS systems onto servers, or any
PC where sensitive, mission-critical data is stored
DON’T COMPROMISE always use an online UPS
5 . Never overload a UPS system, loads in excess of about 80% of
the UPS rated capacity, could result in poor performance or even
total failure under no power conditions.
6 . Only True on-line UPS systems are capable of effectively filtering
generator or poor mains supply. It is wise to test the power quality
prior to specifying the type of UPS for the application
