Thermal Considerations Thermal Resistance °C/Watts

A UACHV150S module has an efficiency of 85%. What is the maximum ambient temperature if 250 Watts of power is needed? A) In free air: B) In free air with heatsink (CV) What would be the maximum output power for a UACHV150S module at an ambient temperature of 50°C with an efficiency of 85%? A) If the module is used in free air. B) If the module is used in an area with forced air at 200 LFM with no heatsink. C) If module with heatsink (CV) is used in free air. At a maximum ambient temperature of 50°c and an efficiency of 85%, how could a UAC150S module be used if 200 Watts of output is required?...
