30、B plug shall meet the USB-IF connector test requirements, shall be compliant to the USB Micro-B cables and connectors specification, Rev 1.01 (Micro-USB 1.01) and shall be rated to meet all electrical specifications. An EPS provided with a detachable cable shall be equipped with an USB standard A re
31、ceptacle to connect to the EPS. The detachable cable assembly, supplied for use with the EPS, shall have Standard A and USB Micro-B plugs and meet the USB-IF cable assembly test requirements for compliant usage of connectors and cables in Micro-USB 1.01. The above requirement also applies to cables
32、used as an adaptor, i.e. when the USB Micro-B is connected to the mobile telephone by an adaptor where the mobile telephone does not have a Micro-USB interface. 5.2 AC input characteristic The EPS shall meet Class II requirements of IEC 60950-1 with a maximum touch current not exceeding 90 A. The EP
33、S AC input shall operate over the following range: voltage range: the rated input voltage range should be at least 100 V to 230 V; frequency: 50 Hz to 60 Hz. 5.3 Environmental specification The EPS operational environmental range over which the DC output characteristics defined in 5.4 shall be maint
34、ained, shall be temperature range: 0 C to +45 C, relative humidity: up to 90 %.

The maximum voltage drop caused by the detachable cable shall be 125 mV when measured across the power pair pins of the USB Micro-B plug, while drawing 500 mA f
36、rom a nominal 5 V source. The minimum rated output current shall be 500 mA. The maximum rated output current shall be 1 500 mA. The maximum output current at any voltage shall not be greater than 1 500 mA. The ripple voltage on the output with a no load current to maximum rated output current shall
37、be no more than 80 mV peak-to-peak measured at 20 MHz bandwidth using the test method as defined in Clause 6. The common mode noise at the DC output when measured in accordance with Clause 6 shall be AC voltage frequency component: 95 V peak-to-peak maximum, EPS switching frequency component: a) the
38、 peak-to-peak voltage measured in the frequency range of 1 kHz to 100 kHz shall not exceed 1 V peak-to-peak; b) the peak-to-peak voltage measured in the frequency range of 100 kHz to 400 kHz shall not exceed 200 mV peak-to-peak; c) the peak-to-peak voltage measured in the frequency range of 400 kHz

40、 amount of slew within any 100 ns window is 1,25 V peak-to-peak. NOTE Noise in the FM and TV bands from the EPS should be minimized as it may cause interference to any FM radio and/or TV function of the mobile telephone to which the EPS is connected. At the time of writing, no suitable method of mea
41、surement has been defined and is the subject of ongoing work. 5.5 Protection The maximum output voltage under Single Fault Condition shall not exceed 9 V. The maximum output current under Single Fault Condition shall not exceed 3 A. The EPS shall not be damaged as a result of either any over-tempera
42、ture condition of the EPS circuitry components which is not due to a fault of the EPS, or any output short circuit condition. If shut down occurs, the unit shall not resume operation until AC power is cycled or the failure condition causing the shut down has been removed. 5.6 EPS detection To enable
43、 the mobile telephone to detect that it is connected to an EPS, the EPS shall meet the USB-IF charging port test requirements for a dedicated charging port as defined in USB Battery Charging Specification, Revision 1.1 (BC 1.1), Section 4.1 Charging Port. BS EN 62684:2010 8 62684 IEC:2011 The top le
44、vel requirements are the EPS shall short the D+ and D- lines with a resistance not greater than 200 , the resistance between the D+ or D- lines of the EPS and either Vbus or GND shall be greater than 2 M, the capacitance between the D+ or D- lines of the EPS and either Vbus or GND shall be less than
45、 1 nF. 5.7 Reliability Durability of the plug and receptacles shall, as a minimum, meet the performance as given in Table 3-1 of Universal Serial Bus, Cables and Connectors Class Document, Revision 2.0 August 2007: USB Micro-B plug: 10 000 cycles; Standard-A receptacle and plug: 10 000 cycles (rugge
46、dized Standard-A). 6 Testing requirements 6.1 General The requirements in Clause 5 have been developed to try to ensure that common EPS perform correctly with any data enabled mobile phone to which they may be connected. Most of the requirements can be verified using existing and well understood mea
47、surement techniques which do not need defining in this International Standard. The common mode voltage and ripple voltage at the DC output can be affected by the load on the output of the EPS. For these parameters, the following test procedures shall be used. 6.2 Common mode voltage of the DC output
48、 a) The EPS shall be connected to an AC power source wherein one or the other of the AC mains is a neutral conductor, bonded to earth either at the upstream service transformer, or locally in the laboratory environment. Rationale 1) In most installations, it is required that one or the other of the
49、AC mains is bonded to earth at the upstream service transformer, and is termed the “neutral” or “return” conductor; and 2) common-mode noise is manifested to the greatest extent when one or the other of AC mains is bonded as such. NOTE Many synthesized AC power supplies produce isolated AC outputs with no connection to earth. Common-mode noise measurements are reduced is such situations, since the EPS common-mode noise source has no real ground refer
