  • Page 25 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.
