Standby supply efficiency
Standby power supply efficiency has been measured and the results are plotted in
As shown, the efficiency during rated load operation is better than 82 %, at both nominal
mains voltages from 50 % to full load.

circuitry. This measurement is representative of the significant low consumption from the
mains required for microprocessor powering. It should be mentioned that the standby supply
efficiency has been calculated measuring the input power at the input connector, including
power loss contribution due to all residual loads connected to mains before and after the
input bridge rectifier, such as the EMI filter and PFC dividers.
