Uninterruptible Power Supply
Consider the following when selecting Uninterruptible Power Supply (UPS)
equipment:
 The minimum amperage requirements for a UPS:
 Calculate VA (Volt-Amps): Locate the voltage and amperage
requirements for each piece of equipment (usually located on a sticker
on the back or bottom of the equipment). Multiply the numbers
together to get VA.
 Add the VA from each piece of equipment together to find the total VA
requirement. Then add 30% to determine the minimum amperage
requirements for the UPS.
 Transition time (the time necessary for the UPS to transfer from utility power
to full-load battery power).
 The longest potential time period the UPS might be required to supply
backup power.
