Intel® Server Chassis H2000 Family TPS Power Sub-System 3.2.14 AC Line Transient Specification AC line transient conditions shall be defined as "sag" and "surge" conditions. "Sag" conditions are also commonly referred to as "brownout", these conditions will be defined as the AC line voltage dropping below nominal voltage conditions. "Surge" will be defined to refer to conditions when the AC line voltage rises above nominal voltage. The power supply shall meet the requirements under the following AC line sag and surge conditions. Table 17. AC Line Sag Transient Performance Duration 0 to ½ AC cycle > 1 AC cycle Sag 95% >30% AC Line Sag (10 sec interval between each saggin) Operating AC Voltage Nominal AC Voltage ranges Nominal AC Voltage ranges Line Frequency 50/60Hz 50/60Hz Performance Criteria. No loss of function or performance. Loss of function acceptable, selfrecoverable. Table 18. AC Line Surge Transient Performance Duration Continuous 0 to ½ AC cycle Surge 10% 30% AC Line Surge Operating AC Voltage Line Frequency Nominal AC Voltages 50/60Hz Mid-point of nominal AC Voltages 50/60Hz Performance Criteria No loss of function or performance No loss of function or performance 3.2.15 Power recovery The power supply shall recover automatically after an AC power failure. AC power failure is defined to be any loss of AC power that exceeds the dropout criteria. 3.2.16 Voltage Interruptions The power supply shall comply with the limits defined in EN55024: 1998/A1: 2001/A2: 2003 using the IEC 61000-4-11: Second Edition: 2004-03 test standard and performance criteria C defined in Annex B of CISPR 24. 3.2.17 AC Line Isolation The power supply shall meet all safety agency requirements for dielectric strength. Transformers' isolation between primary and secondary windings must comply with the 3000Vac (4242Vdc) dielectric strength criteria. If the working voltage between primary and secondary dictates a higher dielectric strength test voltage the highest test voltage should be used. In addition the insulation system must comply with reinforced insulation per safety standard IEC 950. Separation between the primary and secondary circuits, and primary to ground circuits, must comply with the IEC 950 spacing requirements. 3.2.18 AC Power Inlet The AC input connector should be an IEC 320 C-14 power inlet. This inlet is rated for 10A/250 VAC. Revision 1.0 17 Intel order number: G59059-001
