A UAC24S module has an efficiency of 80%. What is the maximum ambient temperature if 100 Watts of power is needed. A) In free air From Table 1: T.«. = 5.1 Using Relation (2) AT = 5.1 (100) [o^jg - l]=127.5°C Ta = 85-127.5 = -42.5°C B) In free air with heatsink (CV). EXAMPLE 2: What would be the maximum output power for a UAC24S module at an ambient temperature of 50°C with an efficiency of 80%. A) If the module is used in free air. From Table 1: T.~ = 5.1 Using Relation (2) 85 -50 - 5-1 P~ [ok - ’] P~=5TO=27-5Wat,S B) If the module is used in an area with forced air at 200 LFM with no...

EXAMPLE 3: At a maximum ambient temperature of 5CTC and an efficiency of 80%, how could a UAC24S module be used if 200 Watts of output power is required. Using Relation (2), we first find the maximum thermal resistance from case to air. AT. T-(200) [gig-l] 85 - 50 = Tic* {5.0} T-™ - 0.7 A} If no heatsink is used. From Table 1, more than 1,000 LFM of airflow is required. B) if a (CV) heatsink is used. 700 LFM of airflow is required. C) If a (CH) heatsink is used. 400 LFM of airflow is required.
