The table above shows the estimated output power for each of the four different types of packages. The 1st section is for use on 230VAC mains or 120VAC mains using voltage doublers. The 2nd section is for a universal input range of 85-265VAC. The table is further divided into Adaptor and Open Frame columns. The Adaptor ratings assume a non-ventilated enclosed adapter measured at 50°C ambient. The Open Frame column is open to the air and is assuming 50°C ambient.
