THERMAL CONSIDERATIONS
Free Convection Derating
250 W: Derate output power linearly at 7.2 W/C over 50C.
500 W: Derate output power linearly at 14.3 W/C over 50C.
750 W: Derate output power linearly at 18.8 W/C over 45C.
Forced Convection
The curves below represent worst case data for chassis mount-
ed (enclosed) front ends, i.e., low line, full load. System con-
ditions such as higher line voltage, lighter load or PC mount
versions of the front ends will increase reliability if the data
here is used as the nominal design criteria.
The sigmoid shape of the curves at low air flows is due to the
chassis mount cover restricting the airflow to the inboard com-
ponents until an airflow of approximately 200 LFM is
achieved. Thereafter, the velocity of air rushing over the cover
causes air to be pulled in through the side perforations, caus-
ing a rapid improvement of cooling of internal components.
