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.
• Whether or not the UPS unit also provides online protection.
