18、 (hereinafter referred to as NEMA WD 9). It does not replace another publication. The effective date is the publication date. The purpose of NEMA WD 9 is to provide necessary guidance for manufacturers and importers of dimmers, photoelectric controls, presence sensors, and multi-outlet bars to meet

19、in a uniform manner the energy consumption reporting requirements of the Mexican “Law for Sustainable Energy Use,” published in the Official Gazette of the Federation on November 28, 2008, Article 23. The content of NEMA WD 9 is, therefore, based on: a) Official Gazette of the Federation, September

20、10, 2010: “Catalog of equipment and appliances for which manufacturers, importers, distributors, and sellers shall include information about their energy consumption.” b) Official Gazette of the Federation, March 14, 2011: “Formats and requirements for the information that shall be submitted by manu

21、facturers and importers of equipment and appliances that use energy for their operation.” Although the Mexican law was the catalyst for developing NEMA WD 9, equipment energy consumption and efficiency are becoming increasingly important topics for consumers and equipment manufacturers worldwide. Id

22、eally, the content of NEMA WD 9 will contribute to an international or regional standard for the energy consumption testing and labeling of dimmers, photoelectric controls, presence sensors, and multi-outlet bars. Consequently, the structure and drafting of NEMA WD 9 follows the rules established by

23、 the International Electrotechnical Commission for its standards. NEMA WD 9 was developed within NEMAs Wiring Device Section, which at the time of development consisted of the following member companies: 2D2C, Inc. Eatons Cooper Wiring Devices Hubbell Incorporated Interpower Corporation KCSM Inc

24、. Legrand/Pass b) Total harmonic voltage content shall not exceed 2% of the fundamental when supplying the device under test, harmonic content being the root mean square summation of the individual harmonics up to and including the 13th; and c) Voltage crest factor (peak to rms) shall be between 1.

25、34 and 1.49. The number of samples selected for testing shall be at least three devices, and the reported energy consumption measurement shall be 5% greater than the 97.5% confidence level of the measurements, based on the actual number of samples tested. Auxiliary power outputs and power supplies t

26、o external devices shall be fully loaded. Note: Annex B contains an example of taking a 3-unit sample and reporting the energy consumption measurement. WD 9-2013 Page 2 2013 National Electrical Manufacturers Association 5.2 TESTING CONFIGURATIONS Full load and standby mode power measurements and cal

27、culations shall be made according to the figures shown in 5.2.1 through 5.2.4 depending on the device type and branch circuit connections required for proper operation. Alternately, device power measurements and calculations may be performed by measuring the power being supplied to the device and su

28、btracting the power in the load(s). This method is represented in Section 5.2.5. 5.2.1 Device Without Neutral Connection See Figure 51.

34、Energy consumption at full load and in standby mode (if applicable) shall be marked on the device and/or the device packaging such that it is easily visible to the end user. For equipment with multiple supply voltages, the manufacturer shall report the energy consumption at the rated supply voltage

35、that results in maximum energy consumption. In addition, the manufacturer may report the energy consumption for other rated supply voltages. Markings and labels shall be clear and legible when received by the customer. Note: Annex A provides examples of energy consumption labeling. WD 9-2013 Page 7

First, calculate the mean of the sample, X, as follows: Where: n is the number of units tested is the sum of the results of n tests To calculate StandbyMode Average (XSBM): XSBM = (0.8188 + 0.8227 + 0.8192)/3 = 0.8202 Watts To calculate Full Load Average (XFL): XFL = (6.4840 + 6.5

43、944 + 6.4520)/3 = 6.5101 Watts WD 9-2013 Page 9 2013 National Electrical Manufacturers Association Then, calculate the standard deviation, s, as follows: Where: X is the mean of sample n is the number of units tested xi is the ith test result Standby Mode Standard Deviation is: sSBM = 0.0017 Full Lo
