6 Thermal Considerations In order to ensure safe operation of the PSU in the end-use equipment, the temperature of the components listed in the table below must not be exceeded. Temperature should be monitored using thermocouples placed on the hottest part of the component (out of direct air flow). See Mechanical Details for component locations. Temperature Measurements (t Maximum mbient) Component Max Temperature C TR Coil 20 C L4 Coil 20 C C2 05 C C52 05 C Service Life The estimated service life of the EPL225 is determined by the cooling arrangements and load conditions experienced in the end application. Due to the uncertain nature of the end application this estimated service life is based on the actual measured temperature of key capacitors with in the product when installed by the end application, The graph below expresses the estimated lifetime based on the temperature of these key components based on the average temperature over the lifetime of the equipment.
