External power supplies.

CFR · 2024-01-01 · US · Title 10

(a) (2) For each basic model of external power supply selected for testing, a sample of sufficient size shall be randomly selected and tested to ensure that— (i) Any represented value of the estimated energy consumption of a basic model for which consumers would favor lower values shall be greater than or equal to the higher of: (A) The mean of the sample, where: (B) The upper 97.5 percent confidence limit (UCL) of the true mean divided by 1.05, where: (ii) Any represented value of the estimated energy consumption of a basic model for which consumers would favor higher values shall be less than or equal to the lower of: (A) The mean of the sample, where: (B) The lower 97.5 percent confidence limit (LCL) of the true mean divided by 0.95, where: (b) (2) Pursuant to § 429.12(b)(13), a certification report shall include the following public product-specific information: (i) External power supplies: The average active mode efficiency as a percentage (%), no-load mode power consumption in watts (W), nameplate output power in watts (W), and, if missing from the nameplate, the output current in amperes (A) of the basic model or the output current in amperes (A) of the highest- and lowest-voltage models within the external power supply design family. (ii) Switch-selectable single-voltage external power supplies: The average active mode efficiency as a percentage (%) value, no-load mode power consumption in watts (W) using the lowest and highest selectable output voltages, nameplate ou
