Name: Present Device Operating Efficiency
Assigned Number: 0x0053
This property represents the current power efficiency of the operating device. The power efficiency is defined as the useful output power divided by the total input power of the device. This efficiency is most affected by the current output level or the input power conditions. The reported value either can be determined by measurement, or can be calculated by the device based on manufacturer model data. This value can be used by building management systems to operate devices in a building with greater power efficiency.
