With regard to the Version 7.0 ENERGY STAR Displays specification, how must Sleep and Off Mode power be calculated for products powered by a low-voltage dc source? Follow

The calculation of Sleep and Off Mode power for products powered by a low-voltage dc source must follow the method of calculating On Mode power for such products. Hence:

PSLEEP = PL - PS

POFF = PL - PS

Where:

PSLEEP is the calculated Sleep Mode power, in watts,

POFF is the calculated Off Mode power, in watts

PL is the ac power consumption, in watts, of the low-voltage dc source with the unit under test (UUT) as the load, and

PS is the marginal loss of the ac power supply of the source, in watts.
