Thermal Considerations Temperature Measurements (Ambient 50 C) In order to ensure safe operation of the PSU in the end-use equipment, the temperature of the Component Max Continuous Temperature C components listed in the table below must not be exceeded. See drawing above for TR4 case 110 C component locations. The temperature should be monitored using K type thermocouples C14 105 C placed on the hottest part of the component (out of any direct air flow). See longform C42 105 C datasheet for more information concerning service life.
