EPS1U Power Supply Design Guide, V1.1

4.3Airflow Requirements

STATUS

Recommended

The power supply shall have a two-speed fan(s) and provide cooling to both the supply and the system. During low-speed fan operation, the power supply shall not exceed a noise level of 38 dBA measured at one meter on all faces. At low fan speed, the power supply shall provide a minimum of 6 CFM of airflow with 0.003 inH2O of system backpressure. At high fan speed, the power supply shall provide a minimum of 10 CFM with 0.006 inH2O of system backpressure.

4.4Temperature Requirements

STATUS

Recommended

The power supply shall operate within all specified limits over the Top temperature range. The average air temperature difference (ΔTps ) from the inlet to the outlet of the power supply shall not exceed the values shown in Table 2. All airflow shall pass through the power supply and not over the exterior surfaces of the power supply.
