Intel S2600CP Technical Product Specification - Page 149

Intel® Server Board S2600CP and Server System P4000CP TPS Intel® Server System P4000CP Power System Options signals or protection circuits. If the AC dropout lasts longer than the holdup time the power supply recovers and meets all turn on requirements. The power supply meets the AC dropout requirement over rated AC voltages and frequencies. A dropout of the AC line for any duration does not cause damage to the power supply. Table 74. AC Line Holdup time Loading Holdup time 75% 12msec 13.2.3.5 AC Line Fuse The power supply has one line fused in the single line fuse on the line (Hot) wire of the AC input. The line fusing is acceptable for all safety agency requirements. The input fuse is a slow blow type. AC inrush current does not cause the AC line fuse to blow under any conditions. All protection circuits in the power supply do not cause the AC fuse to blow unless a component in the power supply has failed. This includes DC output load short conditions 13.2.3.6 AC Line Leakage Current The maximum leakage current to ground for each power supply is 3.5mA when tested at 240VAC. 13.2.3.7 AC Line Transient Specification AC line transient conditions are defined as "sag" and "surge" conditions. "Sag" conditions are also commonly referred to as "brownout", these conditions is defined as the AC line voltage dropping below nominal voltage conditions. "Surge" is defined to refer to conditions when the AC line voltage rises above nominal voltage. The power supply meets the requirements under the following AC line sag and surge conditions. Table 75. AC Line Sag Transient Performance Duration 0 to 1/2 AC cycle > 1 AC cycle AC Line Sag (10sec interval between each sagging) Sag Operating AC Voltage Line Frequency Performance Criteria 95% Nominal AC Voltage ranges 50/60Hz No loss of function or performance >30 Nominal AC Voltage ranges 50/60Hz % Loss of function acceptable, self recoverable Duration Continuous 0 to ½ AC cycle Table 76. AC Line Surge Transient Performance 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 13.2.3.8 Power Recovery The power supply recovers automatically after an AC power failure. AC power failure is defined to be any loss of AC power that exceeds the dropout criteria. Revision 1.2 133 Intel order number G26942-003
