What Is UPS Input Power Factor and Why It Matters

Apr , 12 2025

Power factor (pf) is the difference between the actual energy consumed in an AC circuit and the apparent power. It will be calculated as a decimal or percentage between 0-1 pf and 0-100%, i.e. 0.9 pF=90%. Meaning of UPS power factor UPS input power factor UPS input power factor is the ratio of UPS input active power to input power. UPS is not only a part of the power supply, but also the load of t...
