SPSH4 Server SystemTechnical Product Specification
4.2.4.1 DC Output Rating
The power supply meets the static regulation requirements under the loading conditions
specified in Table 16. The combined continuous output load applied to the power supply will not
exceed 600 W. If the power exceeds 600 W, the power supply should not be subjected to this
maximum current draw for more than 12 seconds.
