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.
