Thermal Foldback

The manual explains the thermal model. At 85°C heat sink temp, the controller begins “foldback”—reducing current limit linearly. At 95°C, output stops entirely. This is not a fault; it is protection. The manual cautions against disabling foldback via software, as it voids the UL listing. This is not a fault; it is protection
