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 K type thermocouples placed on the hottest part of the component (out of any direct air flow).
See Mechanical Details for component locations. See longform datasheet for further information and service life estimates.
