Thermal performances

A thermal analysis of the board has been performed using an IR camera for 85 VAC, 115

VAC, 230 VAC and 265 VAC mains input, full load condition, both with and without the self

supply function. The results are shown in the following figures. When the self-supply

function is used the VIPER06 temperature is higher, due to the power dissipated by the HV-

startup generator.
