COSEL Power Supply, Noise Filter 2025 Product Catalog

DPG-seriesImplementation・Mounting MethodStress onto the pins!When too much stress is applied to the pins may damage internalconnections. Avoid applying stress in excess of that shown in rightfi gure.!The pins are soldered onto the internal PCB.Therefore, Do not bend or pull the leads with excessive force.!Mounting hole diameter of PCB should be 3.5mm to reduce thestress to the pins.!Fix the unit on PCB (fi xing fi ttings) by screws to reduce the stressto the pins. Be sure to mount the unit fi rst, then solder the unit.Less than19.6NLess than19.6NLess than19.6NSoldering!Flow soldering : 260Cless than 15 seconds.!Soldering iron : 450Cless than 5 seconds.DeratingDerating curve for input voltage!Below shows rated output for each input voltage section. Maximum output should be within this range.? DPG500? DPG750Output power [W]500300Output power [W]75050085 90 95 170Input Voltage [AC V]85 90 95 170Input Voltage [AC V]Output voltage derating curve!Use with the conduction cooling (e.g. heat radiation by conduction from the aluminum base plate to the attached heat sink). Below showsthe derating curve based on the aluminum base plate temperature. In the hatched area, the specifi cation of Ripple and Ripple Noise isdifferent from other areas.!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.
