Table 1
mains voltages. As shown, these values are fully compliant with the EPA rev 2.0 external
power supply limits, requiring an average efficiency higher than 87% for output load
between 25% and 100% of the nominal load and no-load consumption lower than
500 mW.
In particular at no load the power consumption is very low, in fact at 230 Vac,
it is just 136 mW and at 115 Vac it is 83 mW.
Overall efficiency compared to “EPA rev. 2.0 EPS”
EPA rev. 4.0 computers power supply compliance
Different from the previous EPS regulation, the “EPA rev. 4.0 computers” requires a
minimum efficiency higher than 80%, measured at 20%, 50% and 100% of nominal load. In
Table 2
computers” requirements is given.
Overall efficiency compared to “EPA rev. 4.0 computers”
Additionally, the “EPA rev.4.0 computers” document poses specific limitations to the
maximum consumption of computers during standby mode, sleep mode and idle state but
this is not sufficient to deduce the required power supply efficiency because the load applied
during these states is not indicated. This information comes from computer manufacturer
