How do I size a UPS unit?

The basic rule of physics that watts = volts x amps is based on direct current circuits.Alternating current (AC) supplies buildings and equipment with energy. AC is more efficient for power companies to deliver, but when it hits the equipment''s transformers, it exhibits a characteristic known as reactance.. Reactance reduces the useable power (watts) that is
