COSEL Power Supply, Noise Filter 2025 Product Catalog

DHS-seriesDerating!Use the power modules with conduction cooling (e.g. heat dissipation from the aluminum base plate to the attached heat sink).Belowshows the derating curves with respect to the aluminum base plate temperature. Note that operation within the hatchedareas will cause asignifi cant level of ripple and ripple noise.!Please measure the temperature on the aluminum base plate edge side when you cannot measure the temperature of the center part ofthe aluminum base plate.In this case, please take 5deg temperature margin from the derating characteristic of below.!It is necessary to note the thermal fatigue life by power cycle. Please reduce the temperature fl uctuation range as much as possible whenthe up and down of the temperature are frequently generated. Contact us for more information on cooling methods.?
