19、f the IT equipment during idle periods within any program. The result is that a minimum amount of energy is consumed in accomplishing the essential functionality of the equipment. The design, process, or construction of the energy management program is not detrimental to the equipment or to its func
20、tionality. The above expresses the result as the minimum amount of energy to accomplish a specific task. Energy management is sometimes expressed as the ratio between two power consumption levels under different modes of operation. When equipment becomes idle after completing its intended function,
21、it receives program instructions to assume an energy saving mode. It may have several different energy saving modes. In one energy saving mode, a hard disk may be switched off. In another energy saving mode, more functions may be switched off in order to provide the maximum saving of energy. In some
22、 cases, the lowest mode is an off mode, where little or no energy is consumed. User or software activity returns the equipment to a higher energy consumption level or to the full-on mode without intervention by the user or an extended restart procedure. If the equipment is mainly intended to be cont
23、inuously operated, it may rarely reach an idle state, so no energy saving mode is required. Page4 EN62018:2003POWER CONSUMPTION OF INFORMATION TECHNOLOGY EQUIPMENT MEASUREMENT METHODS 1 Scope This International Standard defines the test methods used to measure power consumption of information techno
24、logy equipment (ITE) under various modes of operation for the purpose of energy management. ITE includes the products identified in the scope of IEC 60950-1. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only t
25、he edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 60950-1, Information technology equipment Safety Part 1: General requirements 3 Terms and definitions For the purposes of this document, the terms and definitions g
26、iven in IEC 60950-1 and the following apply. Defined terms are printed in bold characters where they occur in the text. 3.1 full-on mode a normal operating condition of the ITE in which all functions are fully powered 3.2 energy saving mode an operating condition of the ITE in which one or more func
27、tions are switched off 4 Test procedure 4.1 Measuring equipment Measurements are made with a suitably calibrated true r.m.s. voltmeter and a wattmeter. The voltmeter shall have an accuracy of 1 % or better at rated voltage. The wattmeter shall have an accuracy of 1 % or better at 100 W and greater.
28、It shall be capable of accurate readings of waveforms having peak factors up to 5. The test instruments shall have a bandwidth of at least 1 kHz. Page5 EN62018:20034.2 Configuration The equipment under test shall be a representative configuration for typical use and capable of performing the functio
29、ns for which it was configured. 4.3 Temperature and humidity If the operational environment is not specified by the manufacturer, or if a temperature range is specified that includes 23 C, the tests are conducted at 23 C 5 C. If a temperature range is specified that does not include 23 C, the tests
30、are conducted at whichever end of the temperature range is closer to 23 C. 4.4 Power source for test 4.4.1 Frequency and waveform The test supply frequency shall be the rated frequency of the EUT. The test supply waveform shall contain less than 5 % total harmonic distortion when the EUT is operatin
31、g at the maximum configuration declared by the manufacturer. 4.4.2 Voltage If the equipment has one or more rated voltages, the measurements are made at one rated voltage and are not repeated for multiple rated voltages. If the equipment has one or more rated voltage ranges, measurements are made at
32、 each end of the selected rated voltage range. NOTE It is recommended that the power source be capable of supplying three times the power actually required by the EUT. 4.5 Power measurements 4.5.1 Full-on mode Readings of input power and voltage in the full-on mode are taken under normal load when t
33、he power has stabilized. If the power varies during the normal operating cycle, the power is taken as the mean of the measured power over a complete operating cycle. 4.5.2 Energy saving mode Readings of input power and voltage in the energy saving mode are taken under normal load when the power has
34、stabilized and not sooner than 1 min after entering the energy saving mode. It is permitted to initiate the energy saving mode manually in the shortest time permitted in the energy management program, to reduce the test duration. It may be necessary to use a password to return to a higher energy con
35、sumption level. Measurements are repeated for each energy saving mode of which the EUT is capable. Page6 EN62018:20035 Records of results of measurements The following is the minimum information that shall be recorded for each configuration tested: EUT manufacturers name and trade mark or identifica
36、tion mark and model or type reference and the serial number of the EUT; configuration and work load used for the test; ambient temperature during the tests; input power supply actual voltage and frequency; power consumption in the full-on mode; power consumption in each applicable energy saving mode
