Temperature should be monitored using thermocouples placed on the hottest part of the component (out of direct air flow). See below for component locations. Temperature Measurements (At Ambient 50 °C) Component Max Temperature °C T1 Coil 120 ° C L3 Coil 120 ° C C64 105 ° C C53 105 ° C Service Life The estimated service life of the CHD250 Series 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 a key capacitors with in the product when installed by the end application. The worst case of the two figures should be taken as the indicative service life in 24/7 operation. The graph below expresses the estimated lifetime of a given component temperature and assumes continuous operation at this temperature.
