Note that operation within the hatched areaswill cause a signifi cant level of ripple and ripple noise. Contact us for more information on cooling methods.!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 fi gure .CQHS1Vin=DC36-60V1002CQHS300 : Vin=DC60 - 76V CQHS350 : Vin=DC60 - 65V1008080Load factor [%]50Vin=36-60V Vin=DC36 - 60VLoad factor [%]50CQHS300 Vin=60-76V : Vin=DC60 - 76VCQHS350 : Vin=DC60 - 65V0(85)-40-200204060801000-40-20020406080(95)100Aluminum base plate temperature Tc [C]Aluminum base plate temperature Tc [C]Tc : Measuring pointAluminum base plateInstruction Manual◆It is neccessary to read the“Instruction Manual”and“Before using our product”before you use our product.Instruction ManualBefore using our producthttps://www.cosel.co.jp/redirect/catalog/en/CQHS/https://en.cosel.co.jp/technical/caution/index.htmlCQHSNOTICECQHS-10? 528 ?
