Temperature

The thermal map at full load measured at 265 VAC and at 85 VAC is displayed in Figure 11

and Figure 12. The ambient temperature was 25 °C. Regarding the measurements visible

below, it can be estimated that the temperature of the components is below AMR even at

85 °C of ambient temperature. This range can be extended by using a bigger Cu heatsink

area connected to the drain of the VIPer06XS.
