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.
