Calculating Volt-Amperage Requirements
To determine the minimum volt-amperage requirements for your UPS:
Locate the voltage and amperage requirements for each piece of equipment. These
1.
numbers are usually located on a sticker on the back or bottom of your equipment.
Multiply the numbers together to get Volt-Amps (VA):
2.
VA = Volts x Amperes
Add together the VA from all the pieces of equipment to find the total VA requirement.
3.
To determine the minimum volt-amperage requirements for your UPS, we recommend
that you add 30% to the total.
UPS Transition Time
Transition time is the time that is necessary for the UPS to transfer from utility power to
full-load battery power. A transition time of less than 20 milliseconds is required for optimum
performance.
