5. Mounting Directions
5-1. Output Derating according to the Mounting Directions
Recommended standard mounting is Method ( A ). Method ( B ), ( C ) and ( D ) are also possible. Refer to the Output
Derating below. Please do not use installation Method ( E ), where the PCB will be on the topside and heat will be
trapped inside the unit.
In the following derating curve, the maximum output current is denoted as 100%.
