To achieve best cooling results, sufficient airflow through the supply must be ensured. Do not block or obstruct the airflow at the rear of the supply by placing large objects directly at the output connector. The PTU2000-12-074NA is provided with rear to front airflow, which means the air enters through the DC-output of the supply and leaves at the AC-inlet as shown in Figure 2. The PTU2000-12-074NA supply has been designed for horizontal operation.
Figure 2. Airflow Direction
The PTU2000-12-074NA provides access via I2C to the measured temperatures of in total 8 sensors within the power supply, see Table 3. The microprocessor is monitoring these temperatures and if warning threshold of one of these sensors is reached it will set fan to maximum speed. If temperatures continue to rise above shut down threshold the main output V1 (or VSB if auxiliary converter is affected) will be disabled. At the same time the warning or fault condition is signalized accordingly through LED, PWOK_H and SMBALERT_L.
