Thermal Considerations
The FHS Series converters are designed for natural or
forced convection cooling.
The maximum allowable
output current of the converters is determined by
meeting the derating criteria for all components used in
the
converters.
For
example,
the
maximum
semiconductor junction temperature is not allowed to
exceed 125°C to ensure reliable long-term operation of
the converters. Contact Power-One for the complete
list of the derating criteria.
Figure 10 shows the maximum output current of the
FHS Series at different ambient temperatures under
both natural and forced (longitudinal airflow direction,
from pin 1 to pin 4) convection.
For example, from Figure 10, the FHS operating at
50C can deliver up to 26A reliably with 100LFM forced
air, while up to 38A reliably with 400LFM forced air.
