Why a UPS?
Cost of Downtime
• The power grid typically provides only about 99.9% reliability
• In other words, almost 9 hours of downtime per year!
• The total cost to the US of power interruptions is $80B annually
1
• Momentary interruptions were responsible for 2/3 of this cost- thus, it is the length
of the downtime, not length of the interruption, that determines the cost
Electrical downtime is a source of substantial cost to our customers-
Accordingly, a UPS is an extremely cost-effective investment
