Temperature should be monitored using K type thermocouples placed on the hottest part of the component (out of direct air flow). See below for component locations. |Temperature Measurements(At Maximum Ambient)|Temperature Measurements(At Maximum Ambient)| |---|---| |Component|Max Temperature °C| |T1 Coil|120°C| |L1, LF1, LF2 Coil|120°C| |EC1|105°C| |EC8|105°C| The estimated service life of the PBR500 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 within the product when installed by the end application, The graph below expresses the estimated lifetime of a given component temperature and assumes continuous operation at this temperature. ## **Estimated Service Life vs Component Temperature** **==> picture [252 x 361] intentionally omitted <==** **----- Start of picture text -----**
