US Department of Energy (DOE): Energy Conservation Program

Mandatory requirement February 10, 2016

US Department of Energy has created a new standard governing the efficiency in external power adapters. The Energy Policy and Conservation Act (EPCA) covers a wide range of consumer, commercial and industrial equipment, including and external power supplies. The new EPCA would expand the 2007 EISA program to include a much wider variety of a power supplies including multiple output EPSs.

Energy Policy and Conservation Act

Nameplate Output Power (Pno)	Maximum Energy Consumption in No-Load Mode
Nameplate Output Power (Pno)	AC-DC, Low Voltage EPS	AC-DC, Basic-Voltage EPS	Multi-Voltage EPS
0 to ≤1W	≤ 0.10W	≤ 0.10W	≤ 0.30W
>1 to ≤49W	≤ 0.10W	≤ 0.10W	≤ 0.30W
>49 to ≤250W	≤ 0.21W	≤ 0.21W	≤ 0.30W
>250W	≤ 0.50W	≤ 0.50W	≤ 0.30W
	Minimum Average Efficiency in Active Mode
0 to ≤1W	> 0.517*Pno + 0.087	> 0.5*Pno + 0.16	≥0.497*ln(Pno) + 0.067
>1 to ≤49W	≥0.0834ln(Pno) - 0.0014Pno + 0.609	≥0.071ln(Pno) - 0.0014Pno + 0.67	≥0.075*ln(Pno) + 0.561
>49 to ≤250W	≥0.870	≥0.880	≥0.860
>250W	≥0.875	≥0.875	≥0.860

Naming Conventions

EPS is External Power Supply
Pno is the nameplate output power of the unit under test. Ln refers to the natural logarithm.
Low Voltage EPS is an EPS where the output voltage <6V. This specification is accepted as Level VI under the International Efficiency Marking Protocol.

The following are exempt from this regulation:

Open Frame Power Supplies
LED Drivers
Active POE Power Supplies
Power Supplies for Medical Application
Power Supplies with Output <3V and >1A
