What do the VA and Wattage ratings of a unit mean?
A. The wattage and VA (volt amp) ratings on a unit indicate the amount of devices you can safely plug into the unit. They are different ways of measuring the amount of power a device takes. For some applications the VA rating and the wattage ratings will be the same (such as an incandescent bulb), however for most computer equipment, the maximum wattage will be about 60-65% of the VA rating. Each UPS has a wattage rating which is displayed on their listing page.
