COSEL Power Supply, Noise Filter 2025 Product Catalog

AC-DC Power Supplies Medical TypeGHA700FInstruction Manual!Given the potential for variation between one application and another,the real test is to measure the critical components temperaturerise when the power supply installed in the end-application.For reliable and safe operation, please make sure the maximumcomponent temperatures rise given in table 3.1 and 3.2 are not exceeded.Operating at the maximum temperature rating results in 3-Years lifeexpectancy. The actual life expectancy can be extended by reducingthe ambient temperature. Please refer to section 4 for moreinformation.!Test Measuring pointsBe aware of the conductive parts during the measurements.Please contact us for more detail.761 2 34 5Fig.3.3 Temperature measurement points locations(For GHA700F-12)1 2 36Silkscreen on PCB4 5PointTable 3.2 Maximum operating temperature(For GHA700F-12)Parts nameSymbolNo.Maximumtemperature[C]Remarks1Line FilterL101902RectifierSS101117case temperature3Input CapacitorC11793(Po[400W),89(Po>400W)4Transformer (Winding)T2011195Transformer (Winding)T3011056Chassis-80**Operating chassis temperature derating of Conduction cooling(Fig.3.3)PointFig.3.2 Temperature measurement points locations(Excluding GHA700F-12)Table 3.1 Maximum operating temperature(Excluding GHA700F-12)Parts nameSymbolNo.Maximumtemperature[C]Remarks1Line FilterL101902RectifierSS101117case temperature3Input CapacitorC11793(Po[400W),89(Po>400W)4Transformer (Winding)T2011105Transformer (Winding)T3011056Silkscreen on PCB-1107Chassis-80**Operating chassis temperature derating of Conduction cooling(Fig.3.2)Power [W]700600500400300200150100(D), (E) mounting0-20-100102030405060Chassis temperature [ C](A), (B), (C)mounting(F) mounting70 75 80Fig.3.4 Conduction cooling derating curve (Reference value)Power [W]700600500400300(B), (C) mounting(A)mounting2001501000(D), (E), (F) mounting-20 -10 0 10 20 25 30 40 50 60Ambient temperature [ C]Fig.3.5 Convection cooling derating curve (Reference value)7080GHA-26
