§ 429.37 Class A external power supplies.
(a) Sampling plan for selection of units for testing.
(1) The requirements of § 429.11 are applicable to external power supplies; and
(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:
Or,
(B) The upper 97.5 percent confidence limit (UCL) of the true mean divided by 1.05, where:
and
(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:
Or,
(B) The lower 97.5 percent confidence limit (LCL) of the true mean divided by 0.95, where:
(b) Certification reports.
(1) The requirements of § 429.12 are applicable to external power supplies except that required information may be reported on the basis of a basic model or a design family. If certifying using a design family, for § 429.12(b)(6), report the individual manufacturer's model numbers covered by the design family.
(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 percent (%), 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 percent (%), no-load mode power consumption in watts (W) at the lowest and highest selectable output voltage, nameplate output power in watts (W), and, if missing from the nameplate, the output current in amperes (A).
(iii) External power supplies that are exempt from no-load mode requirements under § 430.32(w)(1)(iii): A statement that the product is designed to be connected to a security or life safety alarm or surveillance system component, the average active mode efficiency as a percent (%), the nameplate output power in watts (W), and if missing from the nameplate, the certification report must also include 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.
