FORCED AIR COOLING CONDITION
Components must be cool down. As a guide, an air velocity of more than 2.2m/s is required to flow through
the power supply from C9 and T1 side.
The power supply is considered as a component installed to an equipment.
The equipment must be re-evaluated and make sure to meet allowable component temperature.
ALLOWABLE COMPONENT TEMPERATURE
(*) Electrolytic capacitor. Equipment must be re-evaluated for electrolytic capacitor lifetime.
