Forced Air Cooling
Forced air cooling may be required to cool the power unit and its
associated equipment under certain circumstances.
If required, fans may be fitted to the 3000 power supply on request (i.e..
this is a factory fit option), or the equipment may be mounted in a cabinet
with a fan tray fitted.
Factors to be considered when making decisions on forced air cooling are
as follows:
a) The power supply unit is loaded to more than 80% of its rated
output.
b) High ambient temperature.
c) Whether the equipment layout in the cabinet allows efficient
cooling via natural air circulation, e.g. by leaving spaces
between equipments or fitting vent panels.
d) The total power dissipation of all equipments in the cabinet.
