Line-interactive UPS

These UPS units list a line-interactive topology. That is a topology class, not a runtime figure, and it is not the same as online double-conversion. Line-interactive units typically regulate voltage without switching to battery as often as standby models. Check listed VA, watts, and waveform. This page does not size runtime.

How Many VA Do I Need in a UPS?

Calculate the UPS capacity you need by totaling your equipment’s watts, converting watts to VA using power factor, and adding practical headroom. A UPS must meet both its VA and watt limits, while runtime requires a separate battery check.

VA

VA means volt-amperes, a measure of apparent power. It describes the electrical capacity a product can handle, but it is not the same as watts, which measure real power.

Open term

watts

Watts are a unit of electrical power. On a UPS product page, a watt rating usually indicates how much connected equipment the unit can support or how much power a device uses, depending on the label.

Open term

pure sine wave

Pure sine wave is an AC output waveform that closely follows utility power. It can be important for equipment that requires, or works better with, a smooth and consistent waveform.
