Power Supply

Intel® Server Platform SR6850HW4 TPS

5.3.5Auto Restart

Although the power supply may power off under the conditions mentioned in Sections 5.3.3 and

5.3.4it is capable of restarting, either automatically or under program control after the disturbance. In addition, the power supply will not be in a latched state such that any of the operator buttons/buttons do not operate correctly after the disturbance. At no time will the AC power cord have to be removed to clear an error condition.

Auto restart conditions are tested from -40% to -100% AC under-voltage conditions for time intervals ranging from 25ms to 2sec. For each time interval, all of the under-voltage conditions listed below will be tested. These tests are performed at both the lowest and highest nominal operating voltages of the power supply.

Time intervals: 25ms, 40ms, 60ms, 90ms, 130ms, 200ms, 280ms, 400ms, 600ms, 900ms, 1.3sec, and 2.0sec

Under-voltage deviation from nominal AC voltage: -40%, -50%, -60%, -70%, -80%, -90%, - 100%

5.3.6Power Factor Correction (PFC)

The Power Factor Correction (PFC) is 0.97, or greater, for all specified AC input voltages with output loads greater than 90%.

The PFC is 0.75, or greater, for all specified AC input voltages with output loads greater than 50%.

5.3.7AC Input Connector

The AC input receptacle is an IEC-320 16A rated for 250VAC minimum.

5.4DC Output Requirements

The DC output voltages will remain within the regulation ranges shown in the Table 31 when measured at the load end of the connector.
