Relationship between environmental temperature and load
Load and efficiency curve
Power supply to be safe insulation, any side of the metal shell with the outside should be more than 8mm safe distance. If less than 8mm need to pad 1mm thickness above PVC sheet to strengthen the insulation. Safe use, to avoid contact with the heat sink, resulting in electric shock. PCB board mounting hole stud diameter not exceeding 8mm.
