7.5.3 Internal temperature measurement
The internal ambient temperature is measured to provide information of the safe operation of the power supply. The
internal ambient temperature is usually higher than the power supply air intake temperature due to internal power
dissipation. As the power dissipation varies with the load, the internal ambient temperature increases with the load.
Refer to Fig 7-2 for typical internal temperature rise above the air intake temperature versus the load.
Internal temperature calculation example:
1. Hex readback: 68 (0110 1000).
2. Convert hex readback to decimal: 104
3. Calculate the measured temperature:
Temp=104*0.391=40.664
