What Is UPS Efficiency And How Is It Calculated?
UPS efficiency is based on how much of the original incoming power is needed to operate the UPS. For example, an uninterruptible power supply with a 95% efficiency rating will have 95% of the original input powering the load and connected systems, with the remaining 5% energy "wasted" running the UPS. For a UPS, higher efficiency equates to ...
What is UPS efficiency and how is it calculated?
The efficiency of a UPS (uninterruptible power supply) is defined as the ratio between the output electrical power and the input electrical power. For example, in a UPS with 97% efficiency, 97% of the input electrical power is used to power the load (at the UPS output) while 3% is absorbed by the UPS and lost in thermal dissipation.
