STEVAL-ISA112V1
A thermal analysis of the board has been performed using an IR camera for 85 V_AC, 115
V_AC, 230 V_AC and 265 V_AC 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.
