Description and resources

The DC Tranformer 412-12 is a member of the 400 series forward power converter. The transformer includes a softstart, an input undervoltage lockout and a permanent short circuit protection to ensure efficient module protection. The soft start allows current limitation and eliminates inrush current during startup. The short circuit protection completely protects the module against short circuits of any duration by a shutdown and restores to normal operation when the overload is removed. While an overload exists, the transformer remains in the so called hiccup mode, testing periodically if the overload is still applied. The transformer is able to deliver up to 25% more output power even at high temperatures. However, when reaching a critical temperature, the device enters in overload protection to reduce power dissipation and to protect itself from self destruction. The transformer returns back to normal operation and leaves the hiccup mode, when the overload is removed or the internal temperature falls below the critical value.
