UPS's are there not just for current but also for the voltage, there are
numerous situations where the voltage fluctuates and the UPS smoothes that
out as well.

Hi,

Are you sure that it is rated for resistive loads? If that were true, they
should have (to my way of thinking) rated it in Watts. The very fact that
it is rated in VA suggests to me that all that matters is the product of
volts times amps (effectively an amperage limit in this case since the
voltage should be constant).
